Comprehensive guide to bearing materials, lubrication, tolerance grades, leading brands, and industrial applications.
Bearing Materials
Steel Types
Chrome Steel (52100 / 100Cr6)Standard bearing steel with excellent hardness and wear resistance
Carburizing Steel (8620)Case-hardened steel for heavy-duty applications
Stainless Steel (440C, 316, 304)Corrosion resistant for harsh environments
Cage/Retainer Materials
Steel pressed cageEconomical, good for moderate speeds
Brass machined cageExcellent for high-speed and high-temperature applications
Nylon/Polyamide cageLightweight, quiet operation, self-lubricating
Phenolic resin cageHigh strength, good oil retention
Seal Materials
Nitrile rubber (NBR)General purpose, good oil resistance, -40°C to +120°C
Fluorocarbon rubber (FKM/Viton)High temperature and chemical resistance, -20°C to +200°C
Metal shields (zinc-plated steel)Non-contact sealing, high-speed applications
