INA Roller Bearing Inner Ring Steel Bore Diameter 42 mm Outside Diameter 47 mm Overall Length 30 mm IR42X47X30-XL

INA IR42X47X30-XL Roller Bearing Inner Ring is a specialized component manufactured from steel, designed for industrial mechanical applications requiring precise shaft bearing interfaces. This inner ring has a bore diameter of 42 mm, an outside diameter of 47 mm, and an overall length of 30 mm.

Inner rings like this are essential when the shaft cannot be employed as a rolling bearing raceway for needle roller and cage assemblies or drawn cup needle roller bearings. This is typically the case where the shaft cannot be hardened or ground.

The product is engineered to work with needle roller bearings combined with wider inner rings that allow greater axial displacement of the shaft relative to the housing. These characteristics make it suitable for bearings with non-locating bearing functions and enhance operational reliability by providing optimum running surfaces for seal lips.

While it does not carry specific standards or approvals, it conforms to typical industrial usage requirements and is widely applicable in diverse mechanical, industrial machinery, and manufacturing environments.

Constructed from steel for enhanced durability and wear resistance. Bore diameter of 42 mm enables precision fitting in bearing setups. Outside diameter of 47 mm accommodates standard bearing housings. Overall length of 30 mm supports mechanical assembly requirements.

Facilitates larger axial displacements for shaft-to-housing alignment. Improves seal lip running surfaces to reduce wear and leakage. Designed for needle roller bearing applications where shafts are not raceways. Enables use in demanding industrial, mechanical machinery, and manufacturing sectors.

This INA Roller Bearing Inner Ring is ideal for industrial tools and equipment applications requiring reliable bearing accessories and contributes to efficient functioning of rotary bearing units.
