24122Spherical Roller Bearings

24122 Spherical Roller Bearing | 24122CA / 24122CC / 24122K Cage And Application

The 24122 is a versatile double-row spherical roller bearing with standard dimensions of 110×180×69mm. Built with a wide cross-section structure, it offers exceptional self-aligning performance, powerful radial and axial load capacity, and stable low-friction operation. This bearing effectively compensates shaft misalignment, absorbs mechanical vibration, and withstands continuous medium-speed heavy-load and intermittent shock-load operation. Widely used in medium and heavy industrial machinery, the 24122 series covers three mainstream models: 24122CA, 24122CC and 24122K, featuring differentiated cage and bore designs to meet various industrial working conditions.

24122CA Bearing (Solid Brass Cage)

24122CA adopts a one-piece precision machined solid brass cage with symmetrical roller layout and ribless inner ring structure. The high-rigidity brass cage delivers excellent high-temperature resistance, impact stability and anti-fatigue performance during long-term continuous operation. It reduces internal friction, heat accumulation and running noise while maintaining precise roller movement and rotational accuracy. Resistant to deformation under shock loads and harsh environments, this model provides superior operational reliability and extended service life, making it ideal for critical industrial equipment that requires stable and uninterrupted operation.

24122CC Bearing (Stamped Steel Cage)

24122CC is equipped with a two-piece stamped steel cage and floating guide structure. The lightweight steel structure optimizes internal bearing space, expands roller contact area, and improves overall load-bearing efficiency. With a low friction coefficient, reliable wear resistance and stable medium-speed performance, this model features standardized manufacturing, strong versatility and outstanding cost performance. It runs steadily under cyclic heavy-load conditions and resists daily vibration and abrasion, serving as the most cost-effective universal solution for conventional heavy-duty industrial machinery.

24122K Bearing (Tapered Bore)

24122K features a 1:12 tapered bore design with adjustable internal clearance. Compatible with adapter sleeves and withdrawal sleeves, it supports fast installation, disassembly and accurate clearance calibration. The tapered bore structure effectively corrects shaft assembly errors and mechanical deflection, greatly improving the overall stability of heavy-load transmission systems. Inheriting all self-aligning and high-load advantages of standard spherical roller bearings, it enables flexible assembly and simple routine maintenance for frequently serviced mechanical equipment.

Industrial Applications

24122 series bearings are widely applied in heavy industrial transmission fields. 24122CA is suitable for high-temperature and high-impact equipment including metallurgical machinery, rolling mills, heavy-duty reducers and mining machinery. 24122CC fits general heavy machinery such as construction equipment, vibrating screens, chemical and paper-making machines. 24122K is commonly used in industrial fans, large conveyor systems and transmission equipment requiring adjustable clearance and convenient daily maintenance.

Product Summary: 24122CA provides high durability for harsh working scenarios, 24122CC delivers stable cost-effective universal performance, and 24122K offers flexible adjustable assembly solutions, fully covering medium-speed and heavy-load industrial operation requirements.
