CLI thin section bearings are used in instrumentation, robotics, aerospace, medical equipment, cameras and optical equipment. They are chosen for an application where space is at a premium or weight reduction is required. 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. Our chrome steel thin section bearings are also available with a flange on the outer ring.

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.

Chrome steel bearings are not suitable for use in corrosive environments as the steel is not corrosion resistant. Most of our chrome steel thin section bearings can be supplied with metal shields although the larger 6700 series bearings are only available with seals. Many sizes are available with 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 offered 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 6700 series bearings use a crown cage. Many 6800 and 6900 series bearings have a two piece ribbon cage. Attention should be paid to shaft and housing roundness. The inner and outer rings of these bearings are very thin and easily distorted. Poor shaft or housing roundness will greatly increase bearing noise and vibration. 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.
