Polyurethane timing belts

Thermoset polyurethane for superior wear resistance, long lasting performance, strength and accuracy.

A cleaner modern and efficient alternative to rubber, Protorque polyurethane timing belts are particularly suited to a wide range of applications within the food & beverage, packaging and robotics industry. They are also used in applications where smooth running at high speeds are required. Such as: medical equipment, machine tools and optical instruments.

Polyurethane timing belt structure

Protorque maintenance-free trapezoidal tooth endless PU timing belts are produced to the highest European requirements.
Using high-grade polyurethane compound, combined with graded steel cords to improve dimensional stability and provide extreme high-breaking load with low elongation.
Protorque PU timing belts are also available in double-sided design.

Polyurenthane Body

High-grade mixed thermoset polyurethane compound exceptional dimensional stability and rigidity with excellent abrasion resistance. Provides excellent resistance to wear, fatigue and environmental conditions.

Tensile Cord

Encapsulated within the polyurethane layers, steel wires form a tensile cord that delivers an extremely high breaking load, with low elongation to reach high transmission power.

Polyurethane timing belt coil

Temperature

-30°C to +80°C supporting a peak of up to 110°C
