24120 Spherical Roller Bearing | 24120CA / 24120CC / 24120K Cage And Application
The 24120 is a high-performance double-row spherical roller bearing with standard dimensions of 100×165×65mm. Featuring superior self-aligning capability, strong radial and axial load capacity, and low-friction stable operation, this bearing effectively compensates shaft misalignment and absorbs mechanical vibration. It reliably handles continuous heavy loads and intermittent shock loads, making it a core component for medium and heavy industrial transmission machinery. The 24120 series includes three mainstream models: 24120CA, 24120CC and 24120K, with differentiated cage and bore designs to fit diverse industrial working conditions.
24120CA Bearing (Solid Brass Cage)
24120CA 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 toughness and anti-fatigue performance during long-term continuous operation. It minimizes internal friction, heat accumulation and running noise while maintaining precise roller movement and rotational stability. Resistant to structural deformation under shock loads and harsh working environments, this model ensures ultra-high operational reliability and prolonged service life, ideal for critical industrial equipment requiring stable uninterrupted operation.
24120CC Bearing (Stamped Steel Cage)
24120CC 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 significantly improves overall load-bearing efficiency. Featuring a low friction coefficient, outstanding wear resistance and stable medium-speed performance, this model adopts standardized manufacturing with high versatility and excellent cost performance. It operates steadily under cyclic heavy-load conditions and resists daily mechanical vibration and abrasion, serving as the most cost-effective universal option for conventional heavy-duty industrial machinery.
24120K Bearing (Tapered Bore)
24120K 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 effectively corrects shaft assembly errors and mechanical deflection, greatly improving the stability of heavy-load transmission systems. Retaining all self-aligning and super-heavy load advantages of standard spherical roller bearings, it enables flexible assembly and simple routine maintenance, perfect for equipment requiring regular inspection and clearance adjustment.
Industrial Applications
24120 series bearings are widely applied in heavy industrial transmission fields. 24120CA is suitable for high-temperature and high-impact equipment including metallurgical machinery, rolling mills, heavy-duty reducers and mining equipment. 24120CC fits general heavy machinery such as construction equipment, vibrating screens, chemical and paper-making machines. 24120K is commonly used in industrial fans, large conveyor systems and transmission equipment needing flexible installation and convenient daily maintenance.
Product Summary: 24120CA focuses on high durability for harsh working scenarios, 24120CC delivers stable cost-effective universal performance, and 24120K provides flexible adjustable assembly solutions, fully covering medium-speed and heavy-load industrial operation requirements.
