INA Roller Bearing Inner Ring Steel Bore Diameter 70mm Outside Diameter 80mm Overall Length 54mm IR70X80X54-XL

INA IR70X80X54-XL Roller Bearing Inner Ring is a precision-engineered steel component designed for use in mechanical systems where the shaft cannot serve as a raceway for needle roller bearings. This inner ring is essential for needle roller and cage assemblies, drawn cup needle roller bearings with both open and closed ends, and needle roller bearings that require an optimum running surface.

With a bore diameter of 70 mm, an outside diameter of 80 mm, and an overall length of 54 mm, this inner ring provides precise fitting and enhanced performance in rotary bearing applications. Its steel construction offers excellent durability and resistance, making it suitable for demanding industrial environments.

This product is particularly useful when larger axial displacements of the shaft relative to the housing are needed, as it is compatible with wider inner rings to accommodate such movements. It also offers optimum running surfaces, benefiting seal lips and preventing premature wear.

Inner rings like the INA IR70X80X54-XL are commonly used in various industrial sectors including manufacturing, mechanical engineering, fluid power tools, and rotary bearing systems. They are crucial in maintaining alignment and supporting needle roller bearings' structural integrity when direct shaft use is not possible.

Constructed from robust steel for long-lasting service. Precisely sized bore diameter of 70 mm. Compatible outside diameter of 80 mm for accurate installation. Overall length of 54 mm suited for diverse bearing assemblies.

Prevents shaft wear by providing alternative raceways for needle rollers. Supports axial movements in conjunction with wider inner rings. Optimizes sealing efficiency through smooth running surfaces. Essential for drawn cup needle roller bearings and cage assemblies.
