Key Features

The bearing supports high to very high radial forces.
It is designed to allow axial displacement as a non-locating bearing.
High-speed capability is maintained despite line contact between rollers and raceways.
The compact design requires only a small radial space, particularly without an inner ring.
Ideal for compact and economical bearing arrangements in industrial machinery.
Features an open end type and parallel bore suitable for precise applications.
Static load rating of 29 kN and dynamic load rating of 21.1 kN ensure durability under heavy loads.
The bearing type is needle roller, suitable when high load capacity needle bearings are insufficient and cylindrical roller bearings are not required.

Product Description

INA NA6903-XL needle roller bearing features a 17 mm inside diameter and 30 mm outside diameter with a 23 mm race width, designed for industrial mechanical applications.

This needle roller bearing supports high to very high radial forces, making it suitable for demanding rotary bearing and housing unit uses in manufacturing, machinery, and fluid power systems.

The bearing is constructed with an open end type and parallel bore type for precision mounting and is optimized for compact design with small radial envelopes, especially when used without an inner ring.

It allows axial displacement of the shaft relative to the housing, functioning as a non-locating bearing. This makes it highly efficient for applications where axial movement or misalignment tolerance is necessary.

The bearing has a static load rating of 29 kN and a dynamic load rating of 21.1 kN, ensuring robustness and reliable performance under heavy radial loads in industrial equipment. Its needle roller type construction permits high rotational speeds due to line contact between rollers and raceways, helping maintain operational efficiency.

These bearings offer cost-effective solutions for compact machinery setups and are widely used in mechanical, fluid power, and manufacturing industries where reliability and precision are critical.

The bearing supports high to very high radial forces. Designed for use when load capacity of drawn cup needle roller bearings is insufficient. Functions as a non-locating bearing permitting axial displacement. Allows high speeds despite line contact running.

Compensates misalignments between the shaft and housing. Compact and economical bearing design without an inner ring. Static load rating of 29 kN and dynamic load rating of 21.1 kN. Open end type with parallel bore design.

Suitable for industrial mechanical and rotary bearing applications. Explore the wide range of INA Roller Bearings in the Industrial Tools & Equipment category on EnvMart for precision and durability in your machinery and engineering projects.
