Inch Sizes Polyurethane Open-Ended Timing Belts
Polyurethane open-ended timing belts in the inch profile are made of thermoplastic polyurethane, which has high dimensional stability and wear resistance, and steel tensile fiber, in special cases aramid or stainless steel, according to ISO 5296.
The open-ended belts can be welded into endless belts.
Standard width (mm): 25; 31; 37; 50; 75; 100; 150; 200; 400
Standard width (mm): 50; 75; 100; 150; 200; 300; 400
Standard width (mm): 50; 75; 100; 150; 200; 300; 400; 600; 800
- Polyurethane teeth
- Steel cord tension member
- Polyurethane backing
Belts Fields of Use
Polyurethane timing belts are used in all areas, from miniature drives, high-precision positioning and sorting mechanisms, small handheld machines to high-performance drives for building and woodworking machines.
- High transmission power and long life
- Resistant to oil, fuel, benzol, UV radiation and ozone
- Temperature range, depending on application, from −30 °C to +80 °C
Belts Code Description
Belts width in inch × 1/100 (0,37" = 0,37 × 25.4 = 9,5 mm)
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.
|Layer Name||Material||Layer Illustration|
|PAZ (NFT) - nylon fabric on teeth
Low coefficient of friction
|PAR (NFB) - nylon fabric on back
|PAZ + PAR (NFT + NFB) - fabric on teeth and back
Low coefficient of friction and surface protection
The fabric on teeth and back can be combined with all other layers. A complete range of belt surface layers
