PU Molded Endless Timing Belts
PU molded endless timing belts are manufactured without joints by casting them in special molds. Thanks to their continuous tension members, they offer excellent tensile strength with low elongation. This makes them suitable for transmitting high drive power, even at high speeds. Their outstanding mechanical properties make them ideal for demanding drive and positioning applications requiring high precision.
We manufacture molded endless timing belts in various tooth profiles and pitches. The belt length depends on the respective casting mold, and we keep all standard lengths and many special lengths in stock. Individual belt widths of up to 300 mm can be cut from a cast sleeve. By combining different polyurethane compounds and tension member materials, the properties of the timing belts can be specifically adapted to demanding operating conditions.
Belt structure
- Belt body made of molded thermoplastic polyurethane with high abrasion resistance.
- Tension cords made of steel with a high modulus of elasticity ensure excellent dimensional stability under load.
Special tension cords
Stainless steel
Timing belts with tension cords made of stainless steel are suitable for highly corrosive environments or for the food industry. Their tensile strength is slightly lower than that of standard steel tension cords.Aramid
Timing belts with aramid fibers have very good bending properties and absorb shock loads. The belts are lightweight and flexible but tend to elongate under load.Special materials
Special polyurethane compounds are available for applications involving particularly high or low temperatures. Suitable PU materials with documented FDA and EU compliance for food contact are also available for applications in the food industry.
