CLI flanged thin section 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 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. Flanged thin section bearings are used in applications where space is at a premium or weight reduction is required. Thin section bearings have low rotational torque and high rotational accuracy. CLI flanged thin section bearings are also available in stainless steel. 

Chrome steel is the standard material for ball bearings thanks to its high load capacity and low noise properties. Chrome steel thin section bearings, with a steel retainer and a suitable lubricant, can be used at temperatures of 120°C constant or up to 150°C intermittent. Above these temperatures, the load capacity of chrome steel is reduced and the steel undergoes greater dimensional changes.

Most of our chrome steel flanged thin section bearings can be supplied with metal shields, rubber contact seals or low friction non-contact rubber seals. Open bearings are supplied with a light oil lubrication. Shielded or sealed bearings are usually supplied with grease lubrication but shielded bearings can be relubricated with instrument oil for low speed, low friction applications. 

A one-piece crown cage is more common for the smallest and the thinnest section bearings due to space constraints. All F6700 series bearings use a crown cage. Many F6800 and F6900 series bearings have a two piece ribbon cage. 

Attention should be paid to shaft and housing roundness. The inner and outer rings of these flanged bearings are very thin and 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 (radial play) of a thin section bearing can be reduced by as much as 80% of the interference fit.
