Timing Belts

The classical timing belt is the basic belt that serves as base for the subsequent refinement. Here, the two materials polyurethane and neoprene have proved particularly successful. Timing belts are differentiated according to the method of manufacture:

PU open-end / welded belts

Timing belts by the meter, also called open-end timing belts, are produced in a continuous process. In this process, the polyurethane is constantly extruded onto the tension cords. After cooling, the timing belt can simply be rolled up.

If necessary, the desired length is cut and the two ends are welded together. Alternatively, the belt ends can also be closed using a mechanical pin connection. Since the tension cords are interrupted at the joint, this type of timing belt is less resilient than endless timing belts.

PU sleeve timing belts

This type of timing belt is manufactured endless, i.e. without a joint. Potential weak points are thus eliminated. It is manufactured by casting in a mold. After the tension cords have been wound onto a mold core, the mold is closed and the molten polyurethane is pressed into it. For each tooth profile, pitch and length, a separate mold is required. The desired belt width can be cut from the finished timing belt roll as required.

PU flex timing belts

Flex belts also provide the advantage of a closed tension cord. During manufacture, the tension cord is wound onto two forming wheels, whose spacing is adjusted according to the required length of the timing belt. The polyurethane is then extruded all around the tension cords.

Neoprene timing belts

Neoprene timing belts are held in stock in numerous variants, both as open-end belts, which we cut to the required length, and as a roll, which can be individually adjusted in width.
