Product Overview
The 22208 spherical roller bearing is a self-aligning bearing designed for applications where shaft deflection or misalignment is present. With a 40mm bore, 80mm outer diameter, and 23mm width, this 22208 spherical roller bearing accommodates heavy radial loads and moderate axial loads in both directions. The CA suffix denotes a machined brass cage, offering superior strength, heat dissipation, and wear resistance compared to pressed steel cages, making this 22208 spherical roller bearing ideal for high-speed and high-temperature applications. The W33 suffix indicates a circumferential lubrication groove with three evenly spaced oil holes on the outer ring, enabling effective relubrication and extended maintenance intervals. Manufactured from high-grade GCr15 bearing steel to ISO tolerance standards, the 22208 CA/W33 delivers dependable operation in industrial machinery, mining equipment, and material handling systems.
