NU2205 Cylindrical Roller Bearing – High Load Capacity, High Speed & Long Service Life

Product Introduction

The NU2205 Cylindrical Roller Bearing is a single-row cylindrical roller bearing designed for applications requiring high radial load capacity, reliable high-speed performance and stable operation.

The NU design features two integral flanges on the outer ring, while the inner ring has no integral flanges. This structure allows the inner and outer rings to move axially relative to each other, making the bearing suitable for applications where axial displacement caused by thermal expansion or shaft movement needs to be accommodated.

Manufactured from high-quality chrome bearing steel (GCr15), the NU2205 provides excellent wear resistance, fatigue strength and dimensional stability. Its optimized roller and raceway geometry helps distribute loads effectively and reduce friction during operation.

Key Features

High Radial Load Capacity
The cylindrical rollers provide a larger contact area with the raceways compared with conventional ball bearings, allowing the NU2205 to handle high radial loads effectively.

High-Speed Performance
The optimized internal design helps reduce friction and heat generation, making the bearing suitable for applications involving continuous or relatively high-speed rotation.

Axial Displacement Capability
The NU structure allows relative axial movement between the inner and outer rings. This is particularly useful in machinery where thermal expansion may cause shaft displacement.

High Wear Resistance
Made from GCr15 chrome bearing steel, the NU2205 offers good hardness, wear resistance and fatigue strength for demanding industrial applications.

Smooth Operation
Precision-ground raceways and rollers help provide stable rotation, reduced vibration and reliable operating performance.
