Rexroth Multi Technology Linear Motion and Rails

1. Profiled Rail Systems Rexroth offers a comprehensive range of profiled rail system products. As an end-user, you will always find that Rexroth stocks the right product for your specific needs. With the Linear Motion Designer 1.0 calculation program, Rexroth makes it easy to calculate the dimensions of its profiled rail systems.

1.1 Ball rail Systems See chapter about ball rail systems.

1.2 Roller Rail Systems Our roller rail systems allow you to move even the heaviest loads with a minimum of effort all with the design-based rigidity and resulting precision that users of high-performance machine tools and robots require. Our roller rail systems are available in a range of different accuracy specifications.


Heavy-duty size 100 and 125 roller rail systems Rexroth’s size 100 and 125 roller rail systems featuring an antifriction-bearing design are designed for heavy-machinery applications. Ever since Rexroth extended the performance range of its roller rail systems by adding size 100 and 125 solutions to the product range, more and more producers in the heavy machinery and engineering industry have made the transition to state-of-the-art antifriction bearing technology. In applications such as forming systems, heavy-duty metal cutting and handling systems for heavy loads, roller rail systems reduce friction by up to 90 percent compared to conventional slideways. This important performance advantage plus reduced assembly costs reduce machine manufacturing costs and significantly enhance precision. Size 100 has a static load capacity of up to 1,218 kN. The dynamic load capacity with long runner blocks is 632 kN, which is equivalent to the maximum take-off weight of an Airbus 318.

Size 125 roller rail systems have a dynamic load capacity of up to 1,000 kN, and the static load capacity is even higher at 2,000 kN, which is equivalent to the weight of 200 cars.


Profiled Rail Systems for Cast Mineral Mounting Surfaces During production of state-of-the-art cast mineral parts, special casting technology is used to make high-precision components which require no machining and which are mounted on a raw cast mineral base. Rexroth profiled rails with no bottom groove guarantee good contact along the entire mating surface even when high torque is applied to the mounting screws. Click During production of state-of-the-art cast mineral parts, special casting technology is used to make high-precision components which require no machining and which are mounted on a raw cast mineral base. Rexroth profiled rails with no bottom groove guarantee good contact along the entire mating surface even when high torque is applied to the mounting screws. The rails provide high-precision guidance without waviness or height deviations. The new contour reduces potential sources of error during machine installation and commissioning. Cast mineral is becoming increasingly popular in very highprecision machine tools and special machines. This advanced technology reduces the dependency on the steel, foundry and energy market. Rexroth profiled rails with smooth bottom surface exploit the full potential of high-precision polymer-based mounting surfaces. The innovative roller rail systems are available in sizes 35 – 55 and in accuracy classes SP, P and H. They have more than 50 percent additional contact surface compared to profiled rails with a wide groove. As the result they offer the same extremely high-precision mating surface accuracy (
