INA Needle Roller Bearing with 45 mm Inside Diameter, 68 mm Outside Diameter, Open End Type NA6909-ZW-XL

INA NA6909-ZW-XL needle roller bearing features a 45 mm inside diameter and a 68 mm outside diameter, with an open end type design. It is engineered to support high radial loads exclusively and is ideal when the load capacity or accuracy of drawn cup needle roller bearings is insufficient, but the high load capacity of cylindrical roller bearings is not yet required.

This bearing type allows axial displacement relative to the housing, functioning as a non-locating bearing. Its line contact construction enables high-speed performance and tolerance for shaft-to-housing misalignments.

With a parallel bore type and 40 mm race width, this bearing requires minimal radial space and can be configured without an inner ring for compact, cost-effective installations.

INA's needle roller bearing NA6909-ZW-XL is suitable for industrial mechanical machinery applications demanding durability, efficiency, and extended product life. Its design supports industrial, manufacturing, and machinery maintenance use cases where precise and robust radial load support is necessary.

The bearing supports high to very high radial forces effectively. Designed to handle radial loads only, allowing axial displacement between shaft and housing. Offers high-speed operation due to line contact design. Compensates misalignment between shaft and housing with aligning features.

Has a small radial design envelope, suitable for compact installations. Available without an inner ring for space and weight savings. Suitable for non-locating bearing applications. Manufactured with parallel bore type and open end configuration.

Extends product life and contributes to energy savings. Applicable in industrial machinery and mechanical spares requiring reliable needle roller bearings. Explore our comprehensive range of needle Roller Bearings and mechanical spares in the Industrial Tools & Equipment category at EnvMart.
