Bearings

Click to contact an Engineer and learn about Nye Lubricants' greases and oils for 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.

Sintered Bearings

Synthetic Oils Temperature
Range (°C)
Viscosity @ 40°C Application Focus
-60 to 120 17 cSt PAO, plastic compatible, light viscosity oil for improved low torque start-up.
-40 to 175 153 cSt Blend of PAO & alkylated napthalene, plastic compatible, excellent wide-temperature serviceability.
-40 to 125 49.9 cSt PAO, plastic compatible, light viscosity oil; most commonly used viscosity for sintered bearings.
-40 to 120 101.5 cSt PAO, plastic compatible, medium viscosity oil for improved load bearing characteristics.
-25 to 125 550 cSt High viscosity PAO with additives to reduce friction and wear in sintered iron bearings.
-40 to 150 54 cSt Light viscosity oil, good for porous metal sleeve bearings. Low volitility. Excellent oxidation stability.
-40 to 150 35 cSt Light viscosity polyolester-based oil with copper passivator and anti-wear additives for low torque applications.
-65 to 250 150 cSt Medium viscosity, good film strength, exceptional lubricity and chemical inertness, very wide temperature capability.
