22308 Spherical Roller Bearing | CA / CC Cage Heavy-Duty Industrial Bearings
The 22308 spherical roller bearing is a high-spec wide-width double-row self-aligning roller bearing in the 22300 series, serving as an upgraded successor to the 22307 model. With enlarged bore size, optimized roller distribution and upgraded internal load structure, it delivers greater load capacity, stronger vibration resistance and higher running stability for heavy industrial operation. Its precision spherical raceway design enables excellent self-aligning compensation, effectively resolving shaft bending, installation errors and dynamic equipment deflection. Capable of enduring extreme radial loads and stable bidirectional axial loads, the 22308 is engineered for medium-speed, long-cycle and high-shock continuous operation, available in two core configurations: 22308CA and 22308CC.
22308 CA And CC Cage Material And Structural Features
22308CA (Machined Solid Brass Cage): This high-end variant adopts integral precision machined brass cage with superior structural toughness and thermal stability. The finely polished cage structure minimizes rolling friction and locks lubricating grease steadily, resisting deformation and fatigue failure under high-temperature, high-speed and heavy-impact working conditions. It maintains consistent rotational precision during long-term uninterrupted operation, perfectly adapting to high-intensity industrial scenarios with strict durability requirements.
22308CC (Stamped Steel Cage): Featuring an integrated stamped steel frame, this standard model boasts lightweight structure, excellent rigidity and outstanding shock resistance. Its open streamlined design accelerates heat dissipation and flexible roller movement, with low operational resistance and stable mechanical performance. Offering remarkable cost-effectiveness without sacrificing basic load capacity, it is the ideal universal choice for conventional heavy-load and medium-speed industrial equipment.
Core Material And Product Performance Advantages
The 22308 bearing body is forged from premium high-carbon chrome bearing steel, featuring ultra-high hardness, strong compression resistance and excellent anti-fatigue properties under alternating heavy loads. The widened double-row roller structure significantly improves ultimate load capacity and impact tolerance, while the self-aligning design reduces equipment vibration and operating noise. The two cage types achieve differentiated scene adaptation: CC steel cages fit conventional dry and normal-temperature workshops, while CA brass cages target high-temperature, high-load and harsh continuous operating environments.
Industrial Application Scenarios
The dual-version 22308 spherical roller bearing covers diversified heavy-duty industrial fields. The economical 22308CC is widely used in large industrial fans, mine auxiliary equipment, agricultural heavy machinery, conveyor transmission systems and general engineering machinery. The high-performance 22308CA is specially applied in high-temperature and high-load core equipment, including cement processing machinery, metallurgical transmission devices, thermal industry equipment and continuous-operation industrial production units. Reliable and low-maintenance, the 22308 series provides stable and long-lasting heavy-load bearing solutions for modern medium and heavy industrial mechanical systems.
