23122Spherical Roller Bearings

23122 Spherical Roller Bearing | 23122CA / 23122CC / 23122K Cage And Application

The 23122 is a popular double-row spherical roller bearing with standard dimensions of 110×180×69mm. It delivers reliable self-aligning performance, powerful radial and axial load capacity, and consistent low-friction operation. Designed to compensate shaft misalignment, absorb mechanical vibration and withstand continuous heavy loads, the 23122 is a versatile solution for medium and heavy industrial machinery. It is available in three mainstream configurations: 23122CA, 23122CC and 23122K, each with unique cage structures and design features to suit different working conditions.

23122CA Bearing (Solid Brass Cage)

23122CA is equipped with a one-piece machined solid brass cage and symmetrical roller arrangement without inner ring middle ribs. The rigid brass cage provides outstanding high-temperature resistance, mechanical impact resistance and fatigue stability during long-term continuous operation. It minimizes friction heat and running noise while maintaining precise roller guidance, even under sudden shock loads and elevated temperatures. Less prone to deformation than steel cages, the brass structure ensures extended service life and high operational reliability, making 23122CA ideal for critical, high-duty industrial applications that require minimal downtime and maximum durability.

23122CC Bearing (Stamped Steel Cage)

23122CC features a lightweight two-piece stamped steel cage with floating guide design. This optimized internal structure saves space and accommodates larger roller contact areas, significantly improving overall load capacity. With low friction, high limiting speed and excellent wear resistance, the 23122CC runs smoothly under medium-speed and heavy-load conditions. Its standardized structure offers great versatility and superior cost performance, making it the most widely used general-purpose model in the 23122 series. It is highly suitable for standard industrial environments with continuous cyclic loads and regular mechanical vibration.

23122K Bearing (Tapered Bore)

23122K represents the 1:12 tapered bore version of the 23122 spherical roller bearing. It supports easy installation, removal and precise clearance adjustment by matching adapter sleeves and withdrawal sleeves. The tapered bore effectively corrects shaft misalignment and assembly errors, greatly improving mechanical stability during high-torque operation. Retaining all self-aligning and heavy-load advantages of standard spherical roller bearings, 23122K offers flexible assembly and convenient routine maintenance, perfect for frequently serviced mechanical systems.

Industrial Applications

23122 series bearings cover a wide range of industrial transmission scenarios. 23122CA is widely used in metallurgical equipment, rolling mills, heavy-duty reducers and mining machinery that require high temperature and impact resistance. 23122CC serves general heavy machinery including construction equipment, vibrating screens, chemical machines and paper-making equipment. 23122K is commonly installed on industrial fans, large conveyor systems and general transmission equipment needing adjustable installation clearance.

Product Overview: 23122CA offers premium durability for harsh conditions, 23122CC provides stable cost-effective performance for universal use, and 23122K delivers flexible adjustable assembly solutions, fully meeting diverse heavy-load industrial operation demands.
