INA Roller Bearing Inner Ring Steel Bore Diameter 40mm Outside Diameter 50mm Overall Length 20mm IR40X50X20-IS1-XL

INA IR40X50X20-IS1-XL Roller Bearing Inner Ring is a precision-engineered steel component designed to support needle roller bearings in applications where the shaft is unsuitable as a raceway. The inner ring has a bore diameter of 40mm, outside diameter of 50mm, and an overall length of 20mm, making it compatible with various needle roller and cage assemblies.

The inner ring is essential in scenarios requiring wider inner rings for axial displacement of shafts relative to the housing, or where optimum running surfaces are necessary for seal lips. It is made from high-quality steel, ensuring durability and reliable performance in rigorous mechanical environments.

These inner rings are used extensively in industrial machinery, fluid power, and mechanical power transmission systems. They play a crucial role in maintaining bearing reliability and longevity by providing accurate and hardened raceways where shaft treatment is not feasible.

No specific standards or approvals apply to this model, but INA’s manufacturing excellence guarantees consistency and adherence to industry best practices. Inner ring designed for shafts that cannot be hardened or ground to act as raceway.

Supports needle roller bearings with cage assemblies for optimum axial displacement. Steel construction provides long-lasting durability. Precisely machined bore diameter of 40mm, outside diameter of 50mm, and length of 20mm.
