INA Roller Bearing Inner Ring Steel Bore 60 mm Outside Diameter 68 mm Overall Length 45 mm IR60X68X45-XL

INA IR60X68X45-XL Roller Bearing Inner Ring is manufactured from high-quality steel, designed for use in demanding mechanical systems requiring precision bearing components.

This product features a bore diameter of 60 mm, outside diameter of 68 mm, and an overall length of 45 mm, making it suitable for needle roller and cage assemblies, drawn cup needle roller bearings with open or closed ends, where the shaft itself cannot serve as the raceway.

The internal ring allows for greater axial displacement of the shaft relative to the housing, important in applications with non-locating bearing functions. The combination of the steel material and precise dimensions ensures excellent wear resistance and reliability under load.

Inner rings are critical for providing optimum running surfaces for seal lips, which helps maintain sealing efficiency and prolong bearing life in industrial applications.

This component fits in workflows involving rotary bearings and housing units, often seen in manufacturing, mechanical machinery, and fluid power systems where durability and performance are key.

Constructed from steel for reliable mechanical properties. 60 mm bore diameter designed for exact shaft fitting. 68 mm outside diameter matches bearing assembly requirements. 45 mm overall length ensures compatibility in compact spaces.

Supports needle roller bearing assemblies needing hardened raceway alternatives. Allows axial movements in applications with non-locating bearing support. Provides a precise running surface to optimize seal lip function and bearing protection.

Widely used in industrial machinery and fluid power equipment. Enhances operational durability under heavy mechanical load conditions.
