Roller Chain Idler Sprocket Units INA roller chain idler sprocket units are chain guidance and return
units for roller bush chains and roller chains.
They compensate chain
stretch resulting from operation and improve the smoothness of running
of the system at high loads and speeds.
The ready-to-fit units comprise chain sprockets and deep groove ball
bearings. The chain sprockets are made from high strength steel,
sintered iron or plastic (polyamide).
