SKF Single Row Deep Groove Ball Bearing 55 mm ID, 120 mm OD, 29 mm Width, Shielded Cage Sheet Metal 6311-2Z/C3GJN

SKF 6311-2Z/C3GJN single row deep groove ball bearing is engineered for demanding industrial and mechanical applications requiring reliable performance at high speeds. This bearing features a 55 mm inside diameter and 120 mm outside diameter combined with a 29 mm race width that offers suitable dimensions for many rotary applications.

Designed by SKF, a leader in bearing technology, this deep groove ball bearing is shielded to protect internal components from dust and debris, increasing service life and reducing maintenance frequency. It uses a robust sheet metal cage and high-quality steel balls to ensure operational stability.

Its C3 internal clearance permits thermal expansion and accommodates more flexible fitting under varying temperature conditions. The parallel bore type fits standard shaft designs without additional machining requirements. This bearing has a static load rating of 45 kN and a dynamic load rating of 74.1 kN, supporting both stationary and dynamic loads effectively.

With a limiting speed of 6300 rpm, it is suitable for equipment operating at high rotational speeds without sacrificing durability. This bearing type is especially common in manufacturing, industrial machinery, mechanical engineering sectors, and fluid power tools.

Designed for high and very high speeds with low maintenance requirements. Accommodates radial and axial loads in both directions effectively. Features shielded end type to protect against contaminants and retain lubricant.

Cage made from durable sheet metal ensuring structural integrity. Internal clearance of C3 provides additional space for thermal expansion in demanding conditions. Bore type is parallel to fit standard shaft designs accurately.

Static load rating of 45 kN supports substantial static forces. Dynamic load rating of 74.1 kN handles operational stresses efficiently. Limiting speed up to 6300 rpm enabling use in high-speed machinery. Constructed from high-quality steel ensuring longevity and reliability.
