Our spirit of invention and our place in the world. The patent application of the first progressive distributor – the foundation stone of the REBS Central Lubrication Systems company was small but packed a real punch.

REBS Central Lubrication Systems was founded in 1948. The groundwork was laid by company founder Alexander Aristides Rebs back in 1936 when he developed and patented the first progressive distributor. In the post-war period, REBS rapidly developed to become a company which enjoyed continuous steady growth. Thanks to highly motivated employees, several patents and cutting-edge production facilities, REBS has consistently set new standards in terms of cost-effectiveness and service life for central lubrication systems.

Biography of the company

The quality standards achieved by REBS were formally recognised in 1994 when it obtained DIN EN ISO 9001 : 2000 certification status. This certificate is renewed every 3 years and is issued in recognition of a quality management system of the highest standard.

Developments and innovations in all areas ensure that the machines in which REBS equipment is used all operate with minimal levels of friction, also helping to extend their service lives by a large margin. This reduces costs and, through careful use of lubricants, it conserves resources and minimises environmental impact.

The first element distributor

1948 Founding of REBS as a company. Production start-up with one fitter, one skilled operator, one supervisor and one engineer. The company manufactured pumps, progressive distributors and accessories. 1957 Relocation of REBS from Düsseldorf to its own company building in RatingenLintorf, Duisburger Strasse. The company payroll continues to grow. 1962 Dipl.-Ing. Alexander H. O. Rebs also joins the company. 1969 Rising annual sales and payroll numbers lead to a large new construction project.

Following a move from Düsseldorf to Ratingen-Lintorf and several expansion phases, this globally renowned company is now in

As well as central lubrication for oil and grease, the company product range includes oil-air lubrication systems featuring

1973 Patent application for airless chain lubrication with magnetic pumps. Thousands of these pumps are in service, primarily in escalators and in the automotive industry. 1978 REBS starts to develop a single-tube oil-air lubrication system for wheel flanges. In the early Eighties, the invention and granting of a patent for the TURBOLUB® distributor extended the existing oil-air lubrication system to oil-air TURBOLUB® lubrication. Innovation: in TURBOLUB® distributors, the oil-air mixture is distributed dynamically, without moving parts, and therefore without mechanical wear. 1988 Completion of the new company offices and production buildings at the Siemensstrasse site. In the early Nineties, a third generation of the Rebs family joined the company – Dipl.-Ing. Alexander A. Rebs and Dipl.-Ing. Harald Rebs. With their extensive specialist knowledge and team spirit, they made a substantial contribution towards sustaining the continuous growth of REBS as a company. 1992 ...Ongoing expansion of REBS in China, currently with 50 staff on payroll. 2003 Another large new production building is required to handle the steady growth in order volumes. 2004 Modern, new offices are installed in the old production buildings. 2008 Expansion of company buildings to Siemensstrasse. Rise in workforce numbers to 80 employees.

TURBOLUB® System

Wheel Flange lubrication

Chain lubrication

Centrally lubricated – progressively distributed. REBS central lubrication with progressive distributor for oil and grease lubrication systems. The lubrication system can be operated manually or automatically and includes visual and electronic monitoring of the delivery volume.

Our progressive systems combine the advantages of safe and reliable operation and direct system monitoring with the low cost of installing a simple pipework system. Oil and grease is distributed progressively from the pistons in the progressive distributors in carefully measured quantities and is directed straight to the sub-distributors or lubrication points. This system enables the system to be adapted in a variable manner to any desired number of interfaces. The function or displacement volume can be monitored visually or electronically. Use of progressive distributors

Examples of REBS central lubrication with progressive distributors: e.g. grease lubrication With grease lubrication, the main line is always kept at grease delivery pressure by a pneumatic pump. Central lubrication with progressive distributors.

A machine-dependent high-pressure magnetic valve is installed upstream of the REBS progressive distributor. Whenever the valve is actuated, the distributor starts to operate. After one cyclical run of the distributor, the control unit receives a monitoring impulse from the proximity switch on the distributor, indicating that the distributor has completed that cyclical run. The magnetic valves for individual assemblies can be

actuated to different extents depending on the requirement for lubricant. Principle of recirculating oil lubrication When the system requiring lubrication is switched on, oil is conveyed from the delivery pump through the oil filter and progressive distributors to the lube points: there-

after, a defined volume of oil is forced in continuously. The lubrication function can be checked using a pressure gauge or impulse monitoring of the progressive distributor. As oil flows back, it is directed into the container; the contents in the tank are monitored by a level check device.

TURBOLUB® System

Chain lubrication

Widely used in, for example, a rolling mill.

TURBOLUB® distributor

Our patented TURBOLUB® oil-air lubrication system is the optimum solution for an economical and reliable lubrication of bearings. The REBS TURBOLUB® technology is used in a wide range of different applications: in continuous casting plants, in wire and section mills, in addition to hot and cold strip mills. System components located far apart from one another are supplied with their own lube system, a satellite version of the TURBOLUB® system, which can be easily retrofitted with additional SAT stations at any later date. Although these applications and sectors are vastly different from one another, the operating principle for air-oil lubrication is always the same. The central oil pressure unit is the heart of any system. Here, the oil is prepared for further applications. A pump delivers the oil directly or through a progressive distributor to a mixer block which distributes precisely measured quantities of oil and air to the oil-air lines. Inside these lines, a continuous film of oil is formed under the influence of the compressed air from the oil which is fed in pulses and which moves forming a stream on the inside of the oil-air line to the bearings, friction or sealing point. The oil releases from the inner wall of the tube and/or inlet bore, whereby the relevant locations are lubricated. The air creates a positive pressure which prevents particulate from entering the bearings or seal area.

 The core of a TURBOLUB® system: the oil pressure centre.

 The flow controls monitor the air for correct flow.

The benefits of REBS TURBOLUB® technology are perfectly clear:  Doubling of bearing and caster segment service lives  Lower bearing temperatures  Positive pressure protects the bearing against the ingress of dust, scale and water  Precisely metered quantities of lubricant, ensuring no additional heat is generated

through excessive levels of lubrication  Only consumes approx. 5t of oil for 100t of grease  No contamination of the surrounding area  Low maintenance level  Environmental conservation through carefully metered quantities of oil and air

Perfect operation at high temperatures and operating speeds predestine the REBS oilair lubrication system with Turbolub® distributor for use in extreme production processes. This kind of system makes financial sense as well – operating with zero mechanical wear and absolute minimal use of lubricant.

TURBOLUB® System

Wheel Flange lubrication

Chain lubrication

Wear free throughout the curves! Everyone who has heard a tram or train negotiating a bend knows the problem: it makes a screeching noise! This noise is evidence of wear on wheel and rail. As far back as 25 years ago, REBS developed the wheel flange lubrication system based on the ‘One-tube-system’. The system’s successful application world-wide has meant that REBS has become a pioneer in wheel flange lubrication units. The principle behind wheel flange lubrication Lubricant is delivered to a mixer block by a piston pump. From here, lubricant is delivered straight to the nozzles by air with the patented TURBOLUB® distributor. The oilair mixture emerges from the nozzles in the form of minute droplets which coat the wheel flange. Contact between the wheel and rail means that lubricant will naturally be transferred to the following wheels, wear and the irritating squealing is reduced. This lubrication system has been patented by REBS. An additional problem is the reduced capacity of the compressors on board some vehicles. REBS solution is to develop a compact, silent, self contained central compressor unit this is supplied when necessary to generate compressed air for the wheel flange lube systems. The lubricant is only sprayed on in cycles rather than continuously. In this context, the spraying cycles are determined by distance or time or even when going round bends. To meet this challenge, REBS developed the freely programmable ‘Rematic’ control system.

 Risk of vehicle derailing significantly reduced  Reduced train resistance resulting in energy savings  Considerable noise reductions. Particularly with lubricants with high solid content  Environmentally friendly lubricants, also with solids  Low maintenance with units of simple construction  Big cost savings through considerable reduction in wear levels

Typical applications



TURBOLUB® distributor



Wear and noise, especially when negotiating bends, on the wheels and rails of rail vehicles is a problem for operators and people living near the tracks. REBS has been providing a solution for the last 25 years.

 Atomised into minute droplets, lubricant is sprayed onto the wheel flange. Lubricant then reaches the nozzles via a zero-maintenance TURBOLUB® TL-T2 distributor.

Chain lubrication

Lubricated automatically with BLITZ and SKORPION. Whether for moving lubrication points or the oil lubrication of chain studs for all types of conveyor systems – REBS provides the ideal solution for problems which can occur with chain lubrication.

In many industrial areas, chains are used to transmit power or for transport purposes. These chains generally need regular lubrication to prevent wear on chain links. REBS has developed various alternatives for this in its range of central lubrication systems. Principle of BLITZ chain lubrication BLITZ chain lubrication was developed to lubricate the chain pins on all kinds of conveyor and transport systems. Essentially, it comprises an oil container, an electromagnetic piston pump, spray nozzles or oil coating brushes and a control unit.

Block distributor

The operating principle is a simple one. Chain oil is directed to the lube pump. In a cyclical fashion, lubricant is then transported to the spray nozzle. To activate the pump lubrication impulses, the respective control device must first of all initiate an output signal and a proximity switch must then indicate that the chain pins which require lubrication are in the correct position for the spray nozzle. The scanning of the chain pin is done using a visual, inductive or capacitive proximity switch. On the version with brushes to apply a coating of oil, this volume of oil is determined by the setting of a cycle sensor.

station consists of a lubricant container, a pump, a filter, a feedback controller and the control unit. At least one carriage unit is added to this for synchronous movement, as well as one lubricant cylinder. This is equipped with a lubricanting head in the form of a valve and the associated centring mechanism. Function: In standby position before the lubrication stroke, a carriage unit sits in starting position, the lubricant cylinder and centring mechanism is retracted and the sensor counts the chain rollers and/or bearing pins. After a predefined number of chain rollers, the lubricant cycle is initiated. One operating cylinder is moved into position and the carriage unit is driven along with the chain. The second operating cylinder, which centres the lubricant cylinder against the chain roller, is then deployed (i.e. extended). At this point, the head of the lubricant cylinder is inserted into the grease nipple and a predefined volume of lubricant is forced in. On completion of the lubrication process, the cylinders and carriage return to their respective starting positions.

 At the top left, the oil container can be seen with the float switch fitted on top. Beside it to the right is the control unit, below which the magnetic pump is connected: this pump supplies lubricant to the nozzles.

Transport chains running continuously, with what are known in the trade as migrating lube points, used to be a real problem to lubricate. The REBS SKORPION chain lubrication system has finally solved this longstanding problem. The central SKORPION
