T2,5, T5, T10, AT5, AT10 As special the following profile can be manufactured on request MXL, L, H, HTD5M, DD double sided executions.
Tension cords ELATECH® iSync™ timing belts are manufactured with high tensile strength steel cords as standard. All technical data shown in the catalogue are valid for standard cords. Belt with special cords have different mechanical and chemical properties. Special type of tension member such as stainless steel, HFE high flexibility or aramid fiber (Kevlar®) are available on request for special applications. Aramid (Kevlar®) tension cords are used where non magnetic drives are requested. Stainless steel used where high corrosion resistance is required. Fiberglass and polyester used where high flexibility and water restistance are required.

Drive with reverse bending and double sided belt • Driver pulley zmin = 18 • Idler (flat) running on belt back dmin = 15 mm 148
The total power “P” and the total torque “M” transmitted by the belt, are calculated with the following formulas:
P [kW] = Pspez • ze • zk • b / 1000 M [Nm] = Mspez • ze • zk • b / 100

Belt installation Drive installation When installing belt on pulleys, it must be checked before tensioning the drive, that belt teeth and pulley grooves correctly match.
Belt drive tension Correct belt drive tension and alignement are very important to optimize belt life and minimize noise level. In fact improper tension in the belt drive, affect belt fit in the pulley grooves while correct tension minimizes belt pulley interference reducing the noise in the drive. Drive Alignment Pulley misalignment will result in an unequal tension, edge wear and reduction of belt life. Also, misaligned drives are much noisier than correctly aligned drives due to the amount of interference that is created between the belt teeth and the pulley grooves. Proper pulley alignement should be checked with a straight edge or by using a laser alignment tool. Belt width [mm] Allowable pulley misalignment [°]

Idlers Idlers are often a mean to apply tension to the drive when the centre distance is fixed but also to increase the number of teeth in mesh of the small pulley. A toothed idler on the inside of the belt on the slack side is recommended with respect to a back side idler. Drives with inside flat idlers are not recommended as noise and abnormal belt wear may occur. • Idler location is on the slack side span of the belt drive • Diameter for inside toothed idler must be ≥ of the diameter of the small pulley in the drive • Idler must be mounted on a rigid support • Idlers both flat and toothed, should be uncrowned with a minimum arc of contact. • Idler should be positioned respecting: 2 • (dwk + dwg)< A • Idlers width should be ≥ of pulley width B
Backside idlers, although increase the teeth in mesh on both pulleys in the drive, force counterflexure of the belt thus contributing to premature failure. When such an idler is necessary, it should be at least 1,25 times the diameter of the small pulley in the drive and it must be located as close as possible to the small pulley in the drive in order to maximise the number of teeth in mesh of the small pulley.
Belt handling and storage Proper storage is important in order avoid damaging the belts which may cause premature belt failure. Do not store belts on the floor unless in a protective container to avoid damages which may be accidentally caused by people or machine traffic. Belts should be stored in order to prevent direct sunlight and in a dry and cool environment without presence of chemicals in the atmosphere. Avoid belt storage near windows (to avoid sunlight and moisture), near electric motors or devices which generate ozone, near direct airflow of heating/cooling systems.
Do not crimp belts while handling or when stored to avoid damage to tensile cords. Belts must not be hang on small pins to avoid bending to a small diameter. Handle belts with care while moving and installing. On installation, never force the belt over the pulley flange.
Special belts Special belts with cleats, backing and with special moulded shape are designed and manufactured to maximize application performance.
