Radial insert ball bearings
Radial insert ball bearings are single row, rady-to-fit units comprising a solid outer ring, an inner ring extended on one or both sides, cages made from plastic or sheet steel and P, R, L or T seals. Bearings with an inner ring extended on both sides undergo less tilting of the inner ring and therefore run more smoothly.
INA housing units are available in many different designs as plummer block, flanged and take-up housing units. The ready-to-fit units comprise INA cast iron or INA sheet steel housings in which the INA radial insert ball bearings are integrated.

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.
