INA Needle Roller Bearing with 90 mm Inside Diameter and 90 mm Outside Diameter NK73/25-XL

INA NK73/25-XL needle roller bearing, featuring a 90 mm inside diameter and 90 mm outside diameter with a 25 mm race width, is engineered for applications requiring high to very high radial load capacity while maintaining compact dimensions. It is designed with an open end type to support non-locating bearing usage, allowing axial displacement of the shaft relative to the housing, thereby accommodating misalignments effectively.

This bearing type is particularly used when the load capacity or accuracy of drawn cup needle roller bearings with open ends are insufficient and before the high capacity of cylindrical roller bearings is required. It provides robust support for static loads up to 100 kN and dynamic loads up to 60 kN, ensuring reliable performance under demanding operational conditions.

The parallel bore type facilitates precise installation, and the compact race width contributes to an efficient radial design envelope. Despite its small size, the bearing permits high-speed operation owing to line contact rolling elements and an optimized design.

Its versatility makes it suitable for a broad range of industrial sectors, including manufacturing machinery, automotive systems, hydraulics, and other mechanical applications where medium to high radial loads are present without significant axial load demands.

The bearing supports very high radial forces efficiently. Designed for non-locating bearing arrangements, it allows axial shaft displacement with respect to the housing. The needle roller design compensates for shaft and housing misalignments.

Enables compact and cost-effective bearing arrangements due to minimal radial envelope. Ideal when drawn cup needle roller bearings' capacity is insufficient, and cylindrical roller bearings are unnecessary. Suitable for high-speed applications with line contact rolling elements.

Available in multiple sizes and designs for varied industrial needs.

This INA NK73/25-XL needle roller bearing is categorized under Needle Roller Bearings, a critical component in industrial machinery for ensuring reliability and efficiency. Choose this bearing for your applications where compact size and high radial load capacity are paramount.
