INA Needle Roller Bearing 17 mm Inside Diameter, 30 mm Outside Diameter, Sealed End, 12000 RPM Maximum Speed NA4903-2RSR-XL

INA NA4903-2RSR-XL needle roller bearing is a high-performance component featuring a 17 mm inside diameter and a 30 mm outside diameter with a race width of 14 mm. It is designed with a parallel bore and sealed end type, ensuring protection and reliability under demanding operating conditions.

This bearing supports static and dynamic load ratings of 11 kN and 10 kN respectively, making it suitable for applications requiring high radial load capacity. It operates efficiently at limiting speeds up to 12000 rpm when lubricated with grease.

Needle roller bearings like the NA4903-2RSR-XL are used when the load carrying capacity of drawn cup needle Roller Bearings is insufficient and a compact design is crucial. They are designed to only support radial loads, permitting axial displacement, which makes them ideal for use as non-locating bearings in machinery where misalignment compensation is needed.

The compact design allows for reduced radial envelope and economical bearing arrangements. This bearing type is widely used in industrial, manufacturing, and mechanical machinery contexts where durability and precise functionality are required.

The bearing features a sealed end type for enhanced protection. It supports a maximum grease speed of 12000 RPM. The bore type is parallel, ensuring precise fitment. This needle bearing is suitable for high radial force applications.

It permits axial displacement, making it ideal as a non-locating bearing. The bearing enables compensation of misalignments between shaft and housing. Its design allows for compact and cost-effective bearing arrangements.

It is a Better World product offering extended product life and energy savings. Used extensively across industrial tools, fluid power, mechanical machinery, and automotive assemblies, INA NA4903-2RSR-XL ensures high reliability and extended service life.
