INA Needle Roller Bearing 25 mm Inside Diameter, 42 mm Outside Diameter NA6905-XL

INA NA6905-XL is a needle roller bearing featuring a 25 mm inside diameter and a 42 mm outside diameter designed for demanding industrial rotary applications requiring compact radial load support and high-speed capability.

The bearing is open-ended, allowing for easy lubrication and maintenance without the need to remove the cup. It has a parallel bore type that simplifies shaft alignment and installation.

The 30 mm race width enhances the contact surface area, distributing loads effectively to prolong bearing life and maintain performance under stress.

This bearing supports a static load rating of 59 kN, indicating strong resistance to deformation when stationary, and a dynamic load rating of 44 kN, suited for operation under rotational forces.

With a limiting speed of 14,400 rpm, it is engineered for high-speed spindle and machinery operations without compromising durability.

Typical applications include compact gearboxes, bearing housings requiring open-end access, automated machinery cam follower systems, and linear actuator assemblies where precise radial load support is critical.

The bearing's open design facilitates effective routine maintenance. Its needle type construction optimizes radial load capacity in limited spaces. Parallel bore and race width aid in efficient load distribution and shaft fitting.

High limiting speed allows use in fast rotational industrial equipment. Robust static and dynamic load ratings ensure reliable performance under varied load conditions. Suitable for diverse industrial sectors including manufacturing, automation, and machinery maintenance.
