If the load on NSK cylindrical roller bearings becomes too small during operation, slippage between the rollers and raceways occurs, which may result in smearing. Especially with large bearings since the weight of the roller and cage is high.

In case of strong shock loads or vibration, pressed-steel cages are sometimes inadequate.

NSK cylindrical roller bearings with molded polyamide cages (ET type) can be used continuously at temperatures between - 40 and 120°C.
