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. Molded-Oil™ bearings feature a special material that provides a continuous supply of lubricating oil, allowing them to stand up to dust-contaminated environments at atmospheric pressure. Features Long lifeA specialized material provides constant lubrication that extends operating life. Maintenance free Eliminating the need for relubrication, Molded-Oil bearings provide a cleaner environment with longer life than grease-lubricated bearings.
