23218 Spherical Roller Bearing | 23218CA / 23218CC / 23218K Cage And Application
The 23218 is a robust double-row spherical roller bearing with standard dimensions of 90×160×52mm. It features excellent self-aligning properties, strong radial and axial load capacity, and stable low-noise operation. Capable of compensating shaft misalignment and absorbing operational vibration, the 23218 bearing supports continuous heavy-load and intermittent shock-load operation, making it a key component for general and medium-heavy industrial machinery. The series offers three mainstream models: 23218CA, 23218CC and 23218K, featuring different cage structures and bore designs to match various industrial working conditions.
23218CA Bearing (Solid Brass Cage)
23218CA adopts a one-piece machined solid brass cage with symmetrical roller arrangement and ribless inner ring structure. The high-strength brass cage delivers superior high-temperature resistance, impact toughness and fatigue resistance during long-term continuous operation. It effectively reduces internal friction, heat generation and running noise while maintaining precise roller guidance. Resistant to deformation under high temperature and sudden shock loads, this structure ensures outstanding operational stability and extended service life. 23218CA is the high-reliability version for critical industrial equipment that requires stable performance in harsh, high-intensity working environments.
23218CC Bearing (Stamped Steel Cage)
23218CC is equipped with a two-piece stamped steel cage and floating guide design. The lightweight steel cage optimizes internal bearing space, allowing larger roller contact areas and improved overall load capacity. With low friction coefficient, high limit speed and reliable wear resistance, it runs steadily under medium-speed and heavy-cycle load conditions. Featuring standardized structure, high versatility and excellent cost performance, 23218CC is the most popular universal model in the 23218 series, perfectly suited for conventional heavy-duty industrial equipment with stable daily operation demands.
23218K Bearing (Tapered Bore)
23218K is a 1:12 tapered bore spherical roller bearing with adjustable internal clearance. It can be easily installed and disassembled using adapter sleeves or withdrawal sleeves, allowing accurate clearance adjustment and convenient shaft alignment. The tapered bore design effectively compensates assembly errors and shaft deflection, greatly improving transmission system stability. Retaining all self-aligning and heavy-load advantages of standard spherical roller bearings, 23218K supports flexible assembly and simple routine maintenance for frequently serviced mechanical equipment.
Industrial Applications
23218 series bearings cover extensive industrial transmission scenarios. 23218CA is widely used in metallurgical machinery, rolling mills, heavy-duty reducers and mining equipment with high temperature and shock load demands. 23218CC fits general heavy machinery including construction equipment, vibrating screens, chemical and paper-making machines. 23218K is ideal for industrial fans, conveyor systems and general transmission equipment requiring adjustable installation clearance and easy maintenance.
Product Summary: 23218CA provides premium durability for harsh working conditions, 23218CC delivers cost-effective universal performance, and 23218K offers flexible adjustable assembly solutions, fully meeting diverse medium heavy-load industrial operation requirements.
