Polyurethane Truly Endless FLEX Timing Belts
FLEX endless drive or transport timing belts are made to order.
The base of the belt is made of steel tensile fiber, in special cases aramid or stainless steel, which is without any connection (endless). The teeth and spine of the belt are made of thermoplastic polyurethane.
The belts are produced as a single unit without a joint in lengths of up to 22 m and surface layers or carriers can be welded or glued to them.
Belts Construction
- Endless steel cord tension member
- Polyurethane teeth and backing
Belts Fields of Use
Endless polyurethane timing belts are used in all areas of industry as drive or transport belts, in linear drives, positioning and lifting devices.
They are most commonly used in the automotive, textile, glass, ceramic or woodworking industries, as well as in cable companies as drive or towing belts.
Belts Characteristics
- High transmitted power and long service life
- Resistant to oil, petrol, benzene, UV radiation and ozone
- Abrasioon-resistant
- Maintenance-free
- Temperature range, depending on application, from −30 °C to +80 °C

Optional Belt Surface Layers
The choice of the surface layer depends on the type of machine, the ambient temperature, the size of the pulleys, etc. Specifying the surface layer is determined by the material and the thickness of the layer.

Timing Belt Pulleys
For timing belts, types HTDHigh Torque Drive
Because of its tooth height and semi-circular tooth geometry, the HTD profile is especially good at avoiding jump-over of the teeth in operation. The HTD profile is extremely suitable for transmitting high torques., STDSuper Torque Drive
The involute shape of the STD profile allows optimal tooth engagement with the pulley. As a result, it provides precise and quiet operation even at high belt speeds., CTDConti Torque Drive
The CTD profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running., GTRThe GTR profile is a symbiosis of the HTD and STD profiles, combining the benefits of both tooth geometries. The tooth height and width correspond to that of the HTD profile for transmitting extremely high torques and preventing jump-over at the same time, while the involute-shaped flank ensures very smooth running. It also incorporates an additional groove in the tooth head, which enables the air to escape gently from the tooth gap, further enhancing its smooth running., H.O.T.Helical Offset Tooth
The helical toothing of the H.O.T. profile delivers a degree of operational smoothness unrivaled by other timing belts The noise level can be reduced by up to 19 dB, and the polygon effect is almost eliminated, resulting in up to 20% lower vibrations. The profile’s offset toothing means the belt is also self-tracking: Flanges are not necessary, as a result of which the width of the system can be reduced., TTrapezoidal/Trapezprofil
