SKF Cylindrical Bore Shielded Roller Bearing 35 mm ID 55 mm OD 21 mm Race Width Sheet Metal Cage NA 4907.2RS

SKF NA 4907.2RS is a high-quality cylindrical bore roller bearing designed for applications requiring reliable axial and radial support in rotating machinery components. It offers a 35 mm inside diameter, 55 mm outside diameter, and a race width of 21 mm, suitable for diverse industrial environments.

The bearing utilizes bearing steel to provide excellent hardness and fatigue resistance, ensuring prolonged service life under rolling-contact conditions. The sheet metal cage design maintains roller spacing and minimizes frictional heating, enhancing operational stability.

Shielded ends on this single-row bearing limit contamination ingress from dust and debris, allowing for extended lubrication intervals and reliable performance at speeds up to 4800 rpm. The CN internal clearance specification controls axial displacement, making it suitable for applications where predictable bearing movement is critical.

With a dynamic load rating of 31 kN and a static load rating of 43 kN, this bearing is engineered to withstand moderate to heavy loads. The cylindrical bore facilitates direct mounting on shafts, using interference or adapter fits, providing reliable integration into machinery.

Typical applications include gearbox roller supports, electric motor shaft assemblies requiring protection, conveyor idler shafts in manufacturing lines, pump shaft bearing support in fluid handling systems, and machine-tool peripheral components where precise rotational control is essential.

This bearing does not have specified standards or approvals but conforms to SKF series NA 4907.2RS requirements. It is supplied new and is made in India. This single-row bearing has a 35 mm inside diameter and 55 mm outside diameter.

The cage is made from sheet metal for guided rolling elements. Static and dynamic load ratings are 43 kN and 31 kN, respectively. Operating speed is rated up to 4800 rpm with shielded ends. The bearing steel construction ensures durability and fatigue resistance.

Internal clearance classification CN provides controlled axial displacement. Designed for use in gearboxes, motor shafts, conveyors, pumps, and machine tools. Explore more high-quality Roller Bearings and mechanical spares at EnvMart for your industrial and manufacturing needs.
