Dust-Resistant Bearings


Deep Groove Ball Bearing, Spacea, Molded-Oil, 2Comp

NSK's dust-resistant bearings use a special material with a polyolefin resin that has an affinity for lubrication oil. This unique material is sealed in the bearing and provides continuous lubrication in tough environments with dust, wood chips, or other contaminants.

Stainless steel options are available for environments where bearings are also exposed to water.
