INA Needle Roller Bearing 48 mm ID 62 mm OD Sealed Steel Cage RNA6908-ZW-XL

INA RNA6908-ZW-XL Needle Roller Bearing is a high-performance component designed for industrial and mechanical applications requiring durability and precision. Featuring a 48 mm inside diameter and 62 mm outside diameter, this bearing utilizes a sealed design to protect against contaminants and extend product life. The steel cage construction offers robust support for high radial loads, making it suitable for use in demanding environments.

These bearings are employed when the capacity or accuracy of drawn cup needle roller bearings with open ends no longer suffice, but cylindrical roller bearings are not yet necessary. Specifically designed to support only radial loads, they permit axial displacement of the shaft relative to the housing, making them highly suitable as non-locating bearings. This feature compensates for dimensional variations and alignment issues between components.

The line contact characteristic of the needle rollers allows the bearing to operate at high speeds efficiently. The sealed end type provides protection from dust and moisture, thereby increasing maintenance intervals and overall reliability. Due to their small radial design envelope, these bearings are ideal for installation in restricted spaces without compromising load capacity.

Additionally, the design compensates for misalignments between the shaft and housing, enhancing operational flexibility and reducing stress concentrations. The combination of the steel cage and sealing ensures a long service life even under harsh industrial conditions, aligning with sustainability by extending product usage and saving energy.

Typical applications include heavy machinery, industrial equipment, and rotating assemblies in sectors such as manufacturing, automotive, and fluid power systems. The bearing is compliant with no specific international approvals but is recognized for quality and performance within INA's product range.
