INA Needle Roller Bearing 68 mm Inside Diameter 82 mm Outside Diameter NK68/25-XL

INA NK68/25-XL Needle Roller Bearing features a 68 mm inside diameter, 82 mm outside diameter, and 25 mm race width. The bearing is designed with parallel bore type and a robust steel cage, specifically engineered for supporting very high radial loads in industrial and mechanical applications.

Needle roller bearings such as this model are used where load carrying capacity or accuracy of drawn cup needle roller bearings with open ends is insufficient, but the high capacity of cylindrical roller bearings is not required. They permit only radial loads, making them highly suitable as non-locating bearings which allow axial displacement between shaft and housing.

The open end design, combined with the steel cage, also enables operation at high speeds with line contact bearing elements. This enables compensation for misalignments between shaft and housing, useful in aligning needle roller bearing applications. The compact nature of the bearing allows for a very small radial design envelope, contributing to economical bearing arrangements.

Key technical parameters include a static load rating of 89 kN and a dynamic load rating of 49.5 kN, indicating the bearing's excellent durability under load stresses. The bearing does not carry formal industry standards or approvals but is widely accepted for its reliability in roller bearing applications.

This needle roller bearing is suitable for industrial machinery, manufacturing equipment, automotive applications, and general mechanical assemblies requiring precise radial load handling. Its design provides economical and compact solutions where axial displacement tolerance and radial load support are critical.

Supports high to very high radial forces for demanding industrial use. Steel cage material lends robust operation and long service life. Parallel bore type ensures precise mounting and load distribution. Open end type permits high-speed operation with minimal friction.

Compact radial design saves space in assemblies requiring performance and economy. Explore more INA Roller Bearings and mechanical components in our Industrial Tools & Equipment category for reliable and efficient engineering solutions.
