INA 20 Tooth Sprocket, KSR15-B0-06-10-20-08

NA roller chain idler sprocket units are guidance and return units for roller bush chains and roller chains. They can compensate for chain stretch resulting from operation and give smoother system running under high loads and speeds. The ready-to-fit units comprise sprockets and deep groove ball bearings or radial insert ball bearings. The sprockets are made from high strength steel, sintered iron or plastic (polyamide). Sprockets made from plastic give particularly smooth running and generate very little noise. Since the inner ring of the deep groove ball bearing is extended on both sides, no additional spacer rings are required. In series KSR..-B0, the inner ring is located on the shaft by means of a locking collar. The bearing bore of this series has a plus tolerance.
