Timing belts Open length · Polyurethane metric

Metric · Polyurethane · Steel or aramid cord

Polyurethane open length timing belting in metric profiles, cut to the length you need. Polyurethane belting has steel or aramid tension cords for very low stretch, so it holds its position accurately on linear actuators, positioning drives, conveyors and packaging machines. It also resists oil, grease and abrasion better than rubber.

Metric profiles at a glance

Profile Tooth pitch Typical uses
T2.5 / T5 / T10 / T20 2.5 to 20mm Precise linear drives and conveying
AT5 / AT10 / AT20 5 to 20mm Stiffer, stronger teeth for higher loads and accurate positioning
HTD / RPP PU 5mm and 8mm Polyurethane versions of round tooth HTD profiles

Reading the code: T10-25 is a T10 profile (10mm pitch), 25mm wide. T and AT profiles look similar but aren’t interchangeable, so check the pulley profile before ordering.

Choosing the cord

Steel cordThe usual choice for precise positioning, with very low stretch under load.

Aramid cordLighter and resistant to corrosion, for damp conditions and where the belt flexes round small pulleys.
