INA NKXR40-Z-XL Needle 40 mm ID Roller Bearing, 52 mm OD

This roller bearing is a needle-type component designed to support high radial loads in constrained envelope applications. It conforms to DIN 5429 and is intended for installations where Compact cross-sections and high load capacity are required. The bearing operates within engineered rotating systems and is suited to assemblies that demand sustained performance at moderate rotational speeds.

• 56 000N dynamic load rating increases operational lifespan
• 148 000N static load rating resists heavy stationary loads
• Limiting speed 6 000r/min enables moderately high-speed rotation
• Parallel bore construction simplifies straightforward shaft fitting
• Needle roller configuration delivers high load-to-size efficiency

• Suitable for Compact gearbox radial load support
• Used with cam and follower assemblies in drives
• Ideal for transmission shafts in industrial machinery
• Can be used for linkages requiring minimal radial profile
• Used for rotary actuators where space is constrained

It uses a parallel bore that accepts cylindrical shafts without taper adapters.

The high static load capacity allows it to carry significant stationary forces with minimal deformation.

Continuous operation should not exceed the limiting speed of 6 000r/min to maintain performance.

It is manufactured to the DIN 5429 specification, ensuring consistent form and interchangeability.
