Import 22232ma/C3 Roller Bearing — Buy in wholesale FOB from Supplier in China

The 22232MA/C3 is a spherical roller bearing with a 160mm bore diameter, 290mm outer diameter, and 80mm width, designed for heavy radial and axial load applications in demanding industrial environments. This bearing features a brass cage (MA designation indicates machined brass cage) and C3 radial internal clearance, which provides extra clearance for applications involving high temperatures or where interference fits are required. The basic dynamic load rating of 906KN and static load rating of 1419KN indicate substantial load-carrying capacity suitable for mining equipment, large gearboxes, and heavy industrial machinery.

The material specification uses high-carbon chromium bearing steel (GCr15 / AISI 52100), which is the industry standard for premium spherical roller bearings requiring excellent fatigue resistance and wear properties. The C3 clearance class provides approximately 0.065mm additional radial clearance beyond the standard CN class, which is essential for applications where the inner ring operates at elevated temperatures or where the fit causes significant inner ring expansion. The limited speed rating of 1620 rpm (grease lubrication) and 2128 rpm (oil lubrication) defines the operational speed envelope for this bearing size.

This bearing is commonly specified in gearboxes for steel mills, cement plant equipment, crusher machinery, and large conveyor systems where reliability under shock loading is critical. The gross weight of 23.5kg per unit influences shipping calculations and packaging requirements. Typical trade terms involve FOB or CIF shipments from Chinese ports, with payment via T/T or L/C depending on order value and established buyer-supplier relationships. Importers typically source these bearings through authorized distributors or directly from manufacturers for OEM and replacement market applications.
