HTD Polyurethane Open-Ended Timing Belts
Polyurethane open-ended timing belts in HTD 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.
Standard width (mm): 10; 15; 20; 30; 50; 85; 100
Standard width (mm): 25; 40; 55; 85; 115; 150
Standard width (mm): 25; 30; 40; 50; 55; 85; 100; 115; 120; 150
- 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

|XHPII||Extremely high power tensile-strength|
|HS||High stiffness of tension member|
|HSII||Very high stiffness of tension member|
|HP-Niro||Stainless steel tension fibers|
|Aramid||Aramid tension fibers|
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
The most common color of open-ended polyurethane belts with steel tension member is white. ContiTech also offers these belts in black.
Basic HP 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 XHP, XHPII, HS and HSII are mostly produced by ContiTech only in black.
