CLI stainless steel flanged miniature bearings have a solid steel flange on the outer ring. This allows the bearing to be more easily located in a housing. The flange can also help to prevent axial movement of the bearing in the event of a thrust load on the bearing. It is easier to maintain the position of a flanged bearing in the housing where a lot of vibration is present. Flanged bearings are sometimes used where the housing is made from a different material and may expand more than the bearing outer ring at higher temperatures. The resulting loose fit may allow a non-flanged bearing to move within the housing.
These 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.
CLI flanged 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. 316 stainless steel bearings, plastic bearings or full ceramic bearings should be used in very corrosive environments. Stainless steel bearings do not need preservative oil on the exterior surfaces so they can be used without lubrication (dry).
Most of these flanged 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 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.
The standard cage or retainer for a stainless steel flanged miniature bearing is made from either AISI-304 or AISI-420 stainless steel. A one-piece crown cage is more common for the very small and the very thin section bearings due to space constraints. Larger sizes have a two piece ribbon cage.
