Endless welded timing belts

The thermoplastic polyurethane (PU) material used to manufacture PU timing belts can be welded together to form an endless belt. A finger-jointed connection is 80 or 120 mm long, depending on the belt profile, and can achieve a tensile strength of up to 60% of that of a continuous, unjointed timing belt.
Welding an open length of timing belt (meter) creates an endless belt of any desired length. Applications include conveyor systems and convectors, with and without drive pins, as well as material handling and long-distance light transmission. Further information on the tensile strength of various timing belts can be found in the catalog further down this page.

PU timing belts are made of polyurethane, which has high abrasion resistance. The different types of ropes used in the belt ensure varying tensile strengths, regardless of the application.

T20 polyurethane timing belts offer reliable transmission capabilities. The shafts, coated with nylon, can be fitted with PAZ on the toothed side and PAR on the reverse. Various coatings can be applied to the reverse side to address different applications. We can also mount carriers on the reverse side to handle various traction tasks.

It is possible to assemble an open timing belt into a welded timing belt of your desired length using a melting tool.
