INA Roller Bearing Inner Ring Steel 55 mm Bore Diameter 63 mm Outside Diameter 45 mm Overall Length IR55X63X45-XL

INA IR55X63X45-XL roller bearing inner ring is a precision-engineered component made from high-quality steel, intended for use in mechanical, rotary bearing, and industrial machinery applications.

This inner ring is essential when a shaft cannot serve as a rolling bearing raceway for needle roller and cage assemblies, including drawn cup needle roller bearings both with open and closed ends. It is designed to accommodate wider inner rings to allow larger axial displacements of the shaft relative to the housing, particularly in bearings with non-locating bearing functions.

The component has a bore diameter of 55 mm, an outside diameter of 63 mm, and an overall length of 45 mm, ensuring compatibility with specific bearing housings and optimal mechanical fit.

Manufactured from robust steel, the inner ring provides superior running surfaces, improving the performance and longevity of sealing lips in bearing arrangements.

This inner ring is not subject to any special standards or approvals but meets industry expectations for bearing accessories used in sectors such as industrial machinery, mechanical engineering, fluid power, and construction equipment.

Constructed from durable steel material to ensure long-lasting performance. Designed for use where shafts cannot act as rolling bearing raceways for needle roller bearings. Features a bore diameter of 55 mm providing compatibility for specific shaft sizes.

Outside diameter of 63 mm allows fitting into corresponding bearing assemblies. Overall length of 45 mm supports axial displacement requirements in bearing setups. No standards or additional approvals applicable for this model.

Enables optimum running surfaces for seal lips enhancing bearing operation. Suitable for applications requiring precise bearing inner rings in industrial machinery.

This product finds extensive use in industrial tools and equipment applications, particularly in rotary bearings and housing units, mechanical machinery spares, and bearing maintenance or replacement operations.
