Features
       Standard bearings cannot be used in environments where they will be exposed to water or liquid chemicals. In contrast, NTN resin rolling bearings can operate without relubrication, at a lower torque in such environments because their inner and outer rings, balls, and cage are made of unique corrosion-proof self-lubricating materials.
       Note, however, these bearings must be used at a lower load rating and limiting speed because their inner and outer rings are made of resin.
