Description
The SKF 22215 E/C3 is a high-performance spherical roller bearing designed to carry heavy radial and axial loads in both directions, making it suitable for demanding industrial applications. Its self-aligning design accommodates shaft deflection and misalignment, maintaining efficient operation with minimal friction and heat generation.
Belonging to the SKF Explorer performance class, the 22215 E/C3 offers enhanced wear resistance, optimized internal geometry for lower friction, and a significantly extended service life compared to standard spherical roller bearings. It features a durable sheet metal cage, a cylindrical bore for straightforward mounting, and a C3 internal clearance that allows for reliable performance under higher operating temperatures and speeds. Integrated relubrication capability further improves operational reliability and reduces maintenance requirements.
Engineered for versatility, the SKF 22215 E/C3 can be easily combined with housings, sleeves, and lock nuts in modular bearing systems. Its strength, durability, and efficiency make it the preferred choice for heavy-duty machinery applications, including mining, construction, material handling, and other industries where consistent performance is critical.
