INA Needle Roller Bearing, Sealed, Steel Cage, 25 mm ID x 37 mm OD x 17 mm Width RNA4904-2RSR-XL

The INA RNA4904-2RSR-XL is a robust needle roller bearing engineered for demanding industrial applications. With an inner diameter of 25 mm, outer diameter of 37 mm, and race width of 17 mm, this bearing is designed to support high radial loads while maintaining a compact form factor. Its parallel bore type and steel cage ensure precise alignment and prolonged durability, even under continuous operation.

The sealed end construction enhances protection against dust, moisture, and contaminants, helping to extend the bearing's service life. This design allows the bearing to operate reliably in environments where cleanliness and contamination resistance are crucial.

Offering dynamic load rating of 19.5 kN and static load rating of 19.9 kN, the RNA4904-2RSR-XL is well-suited for applications such as rotary shafts, gearboxes, transmission units, and machinery where high speeds and radial load demands are common. Its needle bearing configuration minimizes friction and permits axial displacement, making it optimal for non-locating bearing positions.

Thanks to its compact radial envelope without an inner ring, the bearing is particularly suitable for installations with limited space, offering flexibility in mechanical design and cost-effective bearing arrangements. Steel cage construction delivers exceptional resistance to abrasion and improved load distribution.

Sealed ends reduce maintenance intervals, keeping lubrication intact and minimizing operational downtime.

Industrially, this bearing finds use in manufacturing equipment, automation systems, HVAC units, conveyors, and rotary machinery across sectors such as automotive, machine tool, and heavy engineering.

Supports high radial loads and permits axial shaft displacement for non-locating bearing use. Sealed design for enhanced protection and increased bearing life. Steel cage provides reliable performance under intense conditions.

Suitable for high-speed applications and compensates for shaft-housing misalignment. Compact profiles enable space-saving mechanical installations. Dynamic and static load ratings assure high-performance operation. Used in industrial, manufacturing, and commercial rotary assemblies.

Easy to install thanks to parallel bore and standardized dimensions. Explore more INA needle roller bearings and rotary bearing solutions in the Roller Bearing category for a full lineup to suit your requirements at EnvMart.
