STD S14M Polyurethane Open-Ended Timing Belts
Polyurethane open-ended timing belts in 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. S14M 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.
The open-ended belts can be welded into endless belts.
Belts Construction
- 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.
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

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 |
|---|---|---|
| PAZPolyAmid Zahne – Nylon Fabric on Teeth. Thus sometimes also mentioned as NFT. (NFTNylon Fabric on Teeth. Also mentioned as PAZ – PolyAmid Zahne.) - nylon fabric on teeth Low coefficient of friction |

Belts Colors
The most common color of open-ended polyurethane belts with steel tension member is white. ContiTech also offers these belts in black.
Basic HPHigh Power belts have the same characteristics as white belts. The color is the only difference. Black color is required for some applications due to its design or greater light fastness. White color changes over time - it turns yellow. In addition, any spots are more noticeable on white.
Reinforced types XHPeXtremely High Power, XHPeXtremely High PowerII, HSHigh Stiffness and HSHigh StiffnessII are mostly produced by ContiTech only in black.
