SKF, ID 50 mm ID Cylindrisk, UT 72 mm UT Rullager, 1 Rader, 47.3 kN, CN, NA 4910, 85 kN, Skärmad, 8000rpm

This needle roller bearing, part of the SKF range, features a compact design ideal for applications requiring high-speed performance. With an inside diameter of 50mm and an outside diameter of 72mm, it offers remarkable strength and durability, owing to its robust steel construction. Designed for dynamic loads up to 55kN, this single-row option is particularly suited for applications where space is limited without compromising operational efficiency.

• Designed to accommodate high radial loads with minimal friction

• Utilised in gearboxes for improved torque capability

The dimensions that are crucial for installation include an inside diameter of 50mm, an outside diameter of 72mm, and a race width of 22mm, ensuring compatibility with various housing designs.

This bearing maintains effective performance at reference speeds of 7000rpm and can manage limiting speeds of up to 8000rpm, making it suitable for applications involving high-speed rotation.

The static load rating of 85kN ensures durability under stationary loads, while the dynamic load rating of 55kN indicates its strength when subject to movement, essential for high-load applications.

It is advised to consider the operating environment, as while this bearing is resilient, specific temperature limits should be adhered to, based on application requirements.

The needle roller design allows for a higher load capacity while preserving a smaller footprint, which is beneficial for compact mechanical systems. The single-row configuration further aids in simplifying installation and maintenance.
