NA69/28 Bearings

NA69/28 Bearings are supplied in standard envelopes in both sealed and unsealed configurations.

NA69/28 Needle Roller Bearing designs are easy to install and are especially beneficial in compact designs because of their high load capacity and small sectional height. The caged rollers allow for the heavy duty needle roller bearings to be used in high speed applications.
