INA Roller Bearing Inner Ring Steel Bore Diameter 38 mm Outside Diameter 43 mm Overall Length 20 mm IR38X43X20-XL

INA IR38X43X20-XL Roller Bearing Inner Ring is a precision-engineered steel component with a bore diameter of 38 mm, outside diameter of 43 mm, and an overall length of 20 mm. This inner ring is essential where the shaft cannot be used as a rolling bearing raceway, such as for needle roller and cage assemblies or drawn cup needle roller bearings with open or closed ends.

The inner ring's design ensures optimal running surfaces for seal lips, improving bearing life and performance in demanding mechanical environments. When combined with wider inner rings, it allows larger axial displacement of the shaft relative to the housing, making it suitable for bearings with non-locating functions.

Constructed from high-grade steel, this bearing inner ring offers durability and reliability in industrial applications, including manufacturing, fluid power systems, mechanical machinery, and rotary bearing units.

This component supports seamless integration into needle roller bearings and helps maintain the precision and efficiency of rotary systems. This inner ring is ideal for bearings where shafts cannot serve as raceways. Provides high-quality running surfaces optimized for sealing components.

Steel construction offers excellent strength and wear resistance. Supports axial displacement needs in non-locating bearing applications. Widely applicable in industrial, mechanical, and fluid power equipment.
