Freerun Bearing thin section ball bearings are offered in radial contact, angular contact, 4-point contact and sealed radial contact designs. These bearings are offered in ABEC 1 through ABEC7 precision grades, pre-loaded, corrosion protected, grease-lubricated, and are available with numerous separator, ball, shield, seal, and lubrication options. Standard thin section ball bearings have SAE 52100 steel rings and balls. Freerun thin section ball bearings can be manufactured from other specialty bearing steels to provide corrosion resistance, high temperature capability, alternative load capacity, or chemical compatibility.

Freerun Bearing has manufactured thin section ball bearings from SAE 440C stainless steel to provide corrosion resistance. As an alternative to CRES rings, the entire surface of the rings can

be plated with nodular thin dense chrome (TDC). This plating, which meets AMS 2438,

achieves a molecular bond that will not flake, peel, or separate from the base material.

Special FRB thin section ball bearings have been manufactured from aluminum, 300 series

stainless steel, 17-4PH and other metals. Some special ball materials include CRES 440C,

300 series stainless steel, silicon nitride, and M50 steel.

Freerun Bearing supplies thin section ball bearings with many different lubricants depending on the Mapplication requirements. Greases that are designed specifically for high speed, low torque, water resistance, high temperature, and oscillatory motion can be provided. Additional lubricants, such as dry film, are suitable for use in vacuums and space applications. Radial play (diametral clearance) can be adjusted for mounting fits or temperature changes. Pre-loads can be ground into the bearings to increase or decrease loads to meet particular application requirements. In addition, mounting features, such as flanges, anti-rotation tabs, and mounting holes can be incorporated on the inner and outer rings. Freerun thin section ball bearings may be customized to meet your application's demanding requirements.
