CLI stainless steel AISI-440C thin section bearings are used in applications where space is at a premium or weight reduction is required. Stainless steel thin section bearings have low rotational torque and high rotational accuracy. Thin section bearings are designed for mainly radial loads. They will support axial loads but, with the 6700 series in particular, these should be limited due to the shallower raceways. The smaller sizes in this range are also available with a flanged outer ring. 

Stainless steel thin section 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 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. A stainless steel bearing does 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 bearings can also be relubricated with a food grade lubricant, a high temperature lubricant, a cleanroom lubricant or according to customer requirements.

The standard cage or retainer for a stainless steel miniature 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. 

Special attention should be given to shaft and housing roundness. The rings of stainless steel thin section bearings are easily distorted. Poor shaft or housing roundness will greatly increase bearing noise. Choosing the correct radial play for an application is even more important with thin section bearings. The internal clearance of a thin section bearing can be reduced by as much as 80% of the interference fit.
