Where a shaft cannot be ground and hardened as a seal counterface or where a replaceable seal counterface is required, needle roller bearing inner rings with non-directionally ground raceway (designation IR .. EGS) can be used.
SKF needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.
SKF supplies needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.
