Polyurethane Truly Endless FLEX Timing Belts

FLEX (Truly Endless) are customized drive or transport timing belts.

The belts are manufactured with truly endless tension member. The unique high-tech manufacturing process allows the production of every belt length to a maximum of 22 000 mm. Having no splice or welding, the belts have no weak cross section. They are therefore ideal for high speed power transmission and high load conveying applications. They are manufactured with the teeth and bottom from thermoplastic polyurethane with excellent wear resistance and with high tensile strength steel tension member, in special cases with kevlar or stainless steel tension member. Various surface layers and attachments can be welded or glued on the belts.
