CLI stainless steel miniature bearings are sometimes referred to as instrument bearings or micro bearings and are used in applications as varied as clocks, wind speed measuring instruments, medical instruments, fishing reels, scanners, encoders and small drones. Stainless steel miniature bearings are also available with a flange on the outer ring.
CLI stainless steel bearings, with a stainless steel retainer and a suitable high temperature lubricant, can be used at temperatures of 250°C constant or up to 300°C intermittent. Above these temperatures, the load capacity of stainless steel is reduced so we recommend full ceramic bearings for use over 300°C.
CLI stainless steel bearings are suitable for use in mildly corrosive environments as the steel is corrosion resistant but it is affected by seawater and stronger acids or alkalis. Our 316 stainless steel bearings, plastic bearings or full ceramic bearings should be used in very corrosive environments. CLI stainless steel bearings do not need preservative oil on the exterior surfaces so they can be used without lubrication (dry).
Most of CLI stainless steel miniature bearings can be supplied open or with AISI-304 stainless steel shields. The smallest sizes are only available open. The larger sizes may be available with rubber or Teflon contact seals or low friction non-contact rubber seals. The open miniature bearings are normally oil lubricated. Shielded or sealed bearings are generally pre-lubricated with grease but shielded bearings can also be supplied with instrument oil for low torque applications or completely dry for very low speed applications where very low rotational resistance is required.
