INA RNA4910-2RSR-XL 58 mm ID Roller Bearing Needle, 72 mm OD

This roller bearing is a sealed needle roller element designed for radial load support in Compact assemblies. It operates as a drawn cup type suited to cylindrical shafts and offers sealed protection for enclosed applications, delivering stable rotation where space constraints and continuous operation are factors.

• Sealed construction minimises contamination ingress and maintenance needs
• Drawn cup race reduces overall bearing cross-section for Compact designs
• Single-row layout simplifies integration into confined housings
• Parallel bore ensures consistent shaft alignment under load
• High grease-rated speed capability supports sustained operation at elevated rpm
• Robust static and dynamic capacities manage step and continuous loads

• Suitable for constrained gearbox layouts in light vehicles
• Used for rotating shafts in power transmission modules
• Ideal for Compact actuators and automation equipment
• Can be used for shafts in agricultural machinery attachments
• Used for clutch and linkages requiring sealed rotation

Select housing and shaft fits that maintain radial clearance for needle elements without axial preload to prevent increased friction.

The sealed arrangement restricts external relubrication, so initial grease fill and contamination control determine service life.

Operating close to limiting speed increases thermal growth and lubricant shear, so monitor temperature and avoid prolonged runs at TOP rpm.

A smooth, parallel shaft with fine surface finish reduces wear on the drawn cup and preserves roller contact geometry.
