Lubricant performance in the bearing industry is a major issue – how long and how well it can minimise friction to prevent bearing wear. Nye Lubricants offer 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.
The following two tables are a partial list of popular Nye Lubricants grease and oil for bearing applications. Additional oil and greases are available to meet a wide variety of niche/high performance applications.
