Bearings
Performance of the lubricant in the bearing industry is a major issue – how long and how well it can minimize friction to prevent bearing wear. Nye offers an extensive collection of bearing oils and greases. Each is designed to provide an adequate film of lubricant throughout a range of operating temperatures, speeds and loads, and to resist oxidation, thermal breakdown, and evaporation. Some of Nye’s most popular bearing lubricants are listed below.
Note: For precision bearing applications, Nye’s ultrafiltration service of bearing oils and greases is recommended. Contact a Nye engineer for additional information.
