Timing belts – open-ended, extruded polyurethane

Open-ended optibelt ALPHA LINEAR timing belts are made of extruded, thermoplastic polyurethane with tension cords parallel to the edges. The belts are dimensionally stable and their precise positioning makes them ideal for use in linear drive systems.

It is also possible to apply transparent polyurethane (with a hardness of 85 Shore A), T2, yellow PU foam or other materials directly to the belt in an additional downstream extrusion process.

The optibelt ALPHA LINEAR timing belt can also be given a thin fabric covering on the tooth side in order to reduce friction and noise. Fabric can also be applied to the belt back
