CLI stainless steel, flanged thin section bearings have a stainless 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 a bearing subjected to a thrust load or high vibration. Flanged bearings are sometimes used where the housing is likely to expand more than the bearing outer ring at higher temperatures, leading to a looser housing fit. Stainless steel bearings are used in mildly corrosive applications where space is at a premium or weight reduction is required. These flanged bearings are also available in chrome steel. 

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. Stainless steel, flanged 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. Stainless steel bearings do not need preservative oil on the exterior surfaces so they can be used without lubrication (dry).

The bearings in the table below can be supplied open, with AISI-304 stainless steel shields, with rubber contact seals and some with 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 low speed, low torque applications. If required, these thin section bearings can be relubricated according to customer requirements.

The standard cage or retainer for a flanged, stainless steel bearing is made from AISI-304 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.
