Molded-Oil™
Bearings
NSK Molded-Oil bearings are uniquely designed to prevent the ingress of contamination from detrimentally impacting bearing performance, while providing a continuous and clean source of lubrication to the bearing. Oil-impregnated polyolefin resin serves as a barrier to water and dust, and slowly releases ample lubrication to the bearing with minimal risk of oil leakage for an extended maintenance-free service life and reduced operating costs.
