Product Description

INA RNA6909-ZW-XL is a precision needle roller bearing featuring a 52 mm inside diameter and a 68 mm outside diameter, engineered for demanding industrial and mechanical applications. This bearing incorporates a steel cage and sealed ends to provide robust performance and protection against contaminants, ensuring extended operational life.

Designed to support high to very high radial forces, the bearing offers a static load rating of 127 kN and a dynamic load rating of 79 kN. Its ability to permit axial displacement allows it to function effectively as a non-locating bearing, accommodating axial shaft movements relative to the housing, which is essential for assemblies requiring precise alignment tolerance.

The RNA6909-ZW-XL bearing is ideal for applications where the load carrying capacity or accuracy of traditional drawn cup needle roller bearings with open ends is insufficient and where full cylindrical roller bearings are not yet needed. It achieves this while maintaining a compact radial envelope that is cost-effective and space-saving.

This bearing’s sealed design enhances its durability by protecting the internal components from dirt and moisture. The steel cage construction ensures structural integrity under high-speed conditions and contributes to its ability to compensate misalignments between the shaft and housing.

Typical industrial uses include mechanical machinery assemblies, automotive components, manufacturing equipment, and other applications requiring reliable needle roller bearings capable of handling substantial radial loads without axial load support.

This Needle Roller Bearing is part of INA’s sustainable product range, offering energy savings and extended product life. The compact and economical design makes it suitable for various industries, including construction, manufacturing, and HVAC systems.
