Open-ended optibeltALPHA 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.
Alternatively to the “reinforced top surface” version, it is also possible to apply transparent polyurethane (with a hardness of 85 Shore A) with the designation T2, or yellow PU foam or other materials and versions directly to the belt in an additional downstream extrusion process.
The optibeltALPHA 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.
