TK and ATK Polyurethane Open-Ended Timing Belts
Polyurethane open-ended timing belts with V-guides in TK and ATK profiles are made of thermoplastic polyurethane, which has high dimensional stability and wear resistance, and steel tensile fiber, in special cases aramid or stainless steel.
The open-ended belts can be welded into endless belts.

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 |  |
| PAR (NFB) - nylon fabric on back Surface protection |
Nylon |  |
| PAZ + PAR (NFT + NFB) - fabric on teeth and back Low coefficient of friction and surface protection |
Nylon |  |
The fabric on teeth and back can be combined with all other layers. A complete range of belt surface layers
