ROLAMENTO NTN 6303 2RSC3

With rubber seals inserted into the outer raceway and in contact with the inner race providing protection against the ingress of moisture, dust and other foreign objects. The seals also retain the pre-filled grease in the bearing. Seals can be easily removed for applications that only require one seal. C3 Bearings have an internal clearance to cope with high speed environments where excess heat is generated.
