INA Needle Roller Bearing, 68 mm Inside Diameter, 25 mm Race Width, 68 mm Outside Diameter NK55/25-XL

INA NK55/25-XL needle roller bearing features a 68 mm inside diameter, 25 mm race width, and 68 mm outside diameter, designed for precise and high-load radial applications in industrial machinery.

This needle bearing is capable of supporting high to very high radial forces, making it ideal when the load capacity of drawn cup needle roller bearings is insufficient and the high load capacity of cylindrical roller bearings is not yet required.

The bearing permits only radial loads and is highly suitable for use as a non-locating bearing, allowing axial displacement of the shaft relative to the housing. The open end type construction further facilitates this axial movement.

Its engineering enables high rotational speeds with line contact, and the bearing compensates for misalignments between the shaft and housing, classified as aligning Needle Roller Bearings.

The bore type is parallel, ensuring precise fitting on the shaft, and the bearing's static load rating is 82 kN while the dynamic load rating is 45.5 kN, reflecting robust performance under demanding conditions.

Although no specific industry standards or approvals are cited, the bearing provides a particularly compact, cost-effective, and economical arrangement suited for diverse industrial uses.

This bearing is applicable for mechanical machinery, manufacturing equipment, automotive assemblies, and other commercial industrial applications requiring reliable radial load support and high precision roller elements.

The bearing permits only radial loads and is suitable as a non-locating bearing. It supports high to very high radial forces. The design allows high speeds despite line contact. Compensates misalignments between shaft and housing.
