22307 Spherical Roller Bearing | CA / CC Cage Type Heavy-Duty Bearings
The 22307 spherical roller bearing is a wide-bore, wide-body double-row self-aligning roller bearing upgraded from the 22306 model in the 22300 series. Featuring enlarged roller elements and optimized internal clearance, it delivers higher load capacity, stronger structural rigidity and better vibration resistance than smaller counterparts. Designed with a precision spherical outer raceway, the 22307 bearing provides reliable self-aligning performance to offset shaft deflection, assembly misalignment and operational vibration. It withstands heavy radial loads and moderate dual-direction axial thrusts, stable for medium-speed continuous heavy-duty operation. This model is mainly available in two mainstream cage configurations: 22307CA and 22307CC, tailored for different industrial working conditions.
22307 CA And CC Cage Structure Introduction
22307CA (Solid Machined Brass Cage): Built with one-piece precision machined brass cage, this variant features high mechanical strength, excellent thermal stability and outstanding deformation resistance. The smooth cage surface reduces friction and ensures consistent lubrication retention during long-cycle operation. It performs excellently under high-speed, high-temperature and heavy-impact working conditions, avoiding structural fatigue and roller jamming. Ideal for demanding industrial scenarios that require long-term uninterrupted precision operation.
22307CC (Stamped Steel Cage): Equipped with an integrated lightweight stamped steel cage, this standard version offers high rigidity and strong shock resistance with minimal running resistance. Its streamlined open structure promotes efficient heat dissipation and flexible roller movement. With superior cost performance and stable mechanical properties, the CC cage is the universal, economical choice for conventional medium-speed heavy-load equipment and general industrial environments.
Core Bearing Material And Performance Advantages
The entire 22307 bearing body adopts high-carbon chrome bearing steel as the base material, offering ultra-high hardness, exceptional compression resistance and outstanding anti-fatigue performance under alternating heavy loads. The widened double-row roller layout improves overall load-bearing limit and impact tolerance, while the self-aligning structure effectively reduces equipment operating noise and vibration. The two cage types grant targeted adaptability: steel CC cages suit conventional dry workshop environments, while brass CA cages excel in high-temperature, high-intensity continuous operation scenarios.
Industrial Application Scenarios
Versatile and durable, the 22307 CA and CC spherical roller bearings cover a wide range of medium and heavy industrial applications. The cost-effective 22307CC is widely applied in general heavy machinery, including large industrial fans, logistics conveyor systems, agricultural heavy equipment and ordinary mining auxiliary machinery. The high-performance 22307CA is specially used for high-temperature and high-load equipment such as cement production machinery, metallurgical transmission equipment and industrial processing units with continuous cyclic operation. As a reliable universal heavy-duty bearing solution, the 22307 series effectively lowers maintenance costs and extends mechanical service life for various complex industrial systems.
