INA Needle Roller Bearing 70 mm Inside Diameter, 85 mm Outside Diameter NK70/25-XL

INA NK70/25-XL needle roller bearing features a 70 mm inside diameter and 85 mm outside diameter, engineered for efficient support of high radial loads. It belongs to the needle bearing family designed to optimize load capacity and precision in demanding industrial conditions.

This bearing is constructed with a steel cage and has an open end design, enhancing its suitability for applications where axial displacement of the shaft relative to housing is needed. Its parallel bore and 23 mm race width facilitate installation and integration within mechanical assemblies.

With a static load rating of 92 kN and a dynamic load rating of 50 kN, this bearing effectively supports medium to very high radial forces, making it ideal for manufacturing, construction, automotive, and machinery sectors.

INA needle roller bearings compensate for misalignment between shaft and housing, permitting high-speed operation despite the line contact nature of needle rollers. This design results in compact, cost-effective solutions that minimize the radial design envelope.

The NK70/25-XL is particularly useful when the load carrying capacity or accuracy of drawn cup needle roller bearings is insufficient and the higher capacity of cylindrical roller bearings is unnecessary. It is primarily utilized as a non-locating bearing allowing axial movement for shaft alignment.

Supports high to very high radial forces efficiently. Designed for use when drawn cup needle roller bearings are insufficient for load or accuracy. Permits only radial loads, suitable as non-locating bearings allowing axial shaft displacement.

Compact, economical bearing arrangement with small radial envelope. Accommodates misalignment between shaft and housing due to aligning feature. Constructed with steel cage material for durability. Open end type bearing suitable for various industrial applications.

Static load rating of 92 kN and dynamic load rating of 50 kN. Bore type is parallel with race width of 23 mm.

This needle roller bearing is widely applied in industries including manufacturing equipment, automotive components, HVAC machinery, and general engineering applications. Its robust design and functional versatility make it a reliable choice for various radial load-bearing solutions.
