INA Roller Bearing Inner Ring Steel Bore Diameter 65 mm Outside Diameter 72 mm Overall Length 45 mm IR65X72X45-XL

INA IR65X72X45-XL Roller Bearing Inner Ring is a steel component engineered for industrial rotary bearing assemblies. With a bore diameter of 65 mm, outside diameter of 72 mm, and an overall length of 45 mm, this inner ring is designed to be used where the shaft cannot function as a rolling bearing raceway, especially in needle roller and cage assemblies.

This bearing inner ring is essential when using drawn cup needle roller bearings or needle roller bearings that require hard and ground surface raceways, which the shaft itself cannot provide. It ensures optimal running surfaces required for seal lips and facilitates axial displacement of shafts by being used with wider inner rings in non-locating bearing functions.

Manufactured from high-grade steel, the product offers durability and reliable performance in various industrial applications including mechanical machinery, automotive components, fluid power equipment, and precision engineering.

Typically deployed in industrial machinery, manufacturing equipment, and heavy-duty mechanical systems, this inner ring supports smooth rotary movements and reduces wear caused by inadequate raceway surfaces on shafts.

Constructed from durable steel for optimal strength and longevity. Designed to serve as an inner ring where the shaft cannot be used as a rolling bearing raceway. Bore diameter measures exactly 65 mm ensuring compatibility with precise shaft sizes.

Outside diameter is 72 mm, providing a stable fit within bearing assemblies. Overall length of 45 mm maintains structural integrity and axial space requirements. Ideal for needle roller and cage assemblies requiring high-quality inner rings.

Supports larger axial displacements by combining with wider inner rings in non-locating bearing functions. Provides an optimum running surface for seal lips ensuring efficient sealing and bearing performance.

This product is manufactured to exacting standards that comply with industrial requirements, though no formal certifications are specified. It is new, sourced from India, and designed to integrate seamlessly into rotary bearing setups.
