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.

Belts Construction

Open-Ended Polyurethane Timing Belt Structure

  1. Polyurethane teeth
  2. Steel cord tension member
  3. 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.

Belts Characteristics

  • High transmission power and long life
  • Resistant to oil, fuel, benzol, UV radiation and ozone
  • Wear-resistant
  • Temperature range, depending on application, from −30 °C to +80 °C
  • Maintenance-free

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
Nylon PAZ (nylon fabric on teeth)
PAR (NFB) - nylon fabric on back
Surface protection
Nylon PAZ (nylon fabric on back)
PAZ + PAR (NFT + NFB) - fabric on teeth and back
Low coefficient of friction and surface protection
Nylon PAZ PAR (fabric on teeth and back)

The fabric on teeth and back can be combined with all other layers. A complete range of belt surface layers
