The tensioning wheels or sprockets for INA chains are units of guidance and forwarding of chains, being valid for normal chains and rollers. They serve to compensate for the elongations of the chains, which occur throughout the service life by the operation itself, improve the smoothness of the ride and increase the performance of the system under high loads and speeds.

The units are supplied ready for assembly, are composed of wheel for the chain and rigid ball bearing already assembled. The tensioning wheels for chains are made of high-strength sintered steel. As the inner ring of the rigid ball bearing is extended on both sides, no additional separator rings are required.

The inner ring is fixed to the shaft by an eccentric tensioning ring. The drill in this series has a positive tolerance. In this way, unhanhanized shafts up to ISO h9 tolerance can be used under medium loads and speeds.
