INA Roller Chain Idler Sprocket Unit KSR16-L0-10-10-17-09

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. Since the inner ring of the deep groove ball bearing is extended on both sides, no additional spacer rings are required.
