INA Roller Bearing Inner Ring Steel Bore 45 mm Outside Diameter 55 mm Overall Length 22 mm IR45X55X22-XL

INA IR45X55X22-XL Roller Bearing Inner Ring Steel is engineered for industrial and mechanical applications requiring high-performance bearing components. This inner ring is essential where the shaft cannot serve as a rolling bearing raceway, particularly in needle roller and cage assemblies as well as drawn cup needle roller bearings.

The component features a bore diameter of 45 mm, an outside diameter of 55 mm, and an overall length of 22 mm to match precise engineering requirements. Constructed from robust steel, this inner ring provides excellent surface conditions to support seal lips and withstand operating stresses.

This inner ring allows greater axial shaft displacement in bearings with non-locating functions, enhancing reliability in diverse mechanical systems. It is widely used across industrial machinery, fluid power systems, automotive, manufacturing, and maintenance applications.

Made from high-quality steel for durability and wear resistance. Precision bore and outside diameter for accurate fitment. Supports needle roller bearing assemblies requiring wider inner rings. Improves axial displacement capacity in relevant bearing applications.

Enhances running surface quality for sealing components. Ideal for mechanical, manufacturing, and industrial fluid power systems. Compatible with various needle roller bearing designs. It contributes to the smooth operation and longevity of rotary bearing units.
