BI 2050 R6 NADELLA 50x62,1x28 - Inner Ring for Needle Roller Bearing

Precision inner ring for industrial needle bearings

Hardened raceway for demanding industrial applications

Reliable B2B component for heavy-duty bearing units

Technical specification and application

The BI 2050 R6 NADELLA 50x62,1x28 is a precision inner ring for needle roller bearing assemblies, designed for applications where the shaft cannot serve directly as a hardened raceway. With dimensions 50 x 62,1 x 28 mm, this component provides a ground and hardened running surface for needle rollers, ensuring stable radial load performance and long service life.

Manufactured from high-grade bearing steel and finished to tight tolerances, the BI 2050 R6 inner ring guarantees high durability, reduced friction, and consistent load distribution. It is commonly used in industrial applications, gearboxes, heavy machinery, and production equipment where compact radial bearing solutions are required.

This inner ring works as a critical element within a bearing unit, improving overall operational reliability. When integrated into a complete system - whether alongside a needle roller bearing, a housing assembly, or even in systems where ball bearings are used in adjacent positions - it supports efficient torque transmission and minimizes premature wear.

Key features

• Inner diameter: 50 mm

• Outer diameter: 62,1 mm

• Width: 28 mm

• Hardened and precision-ground raceway

• Designed for high radial loads

• Suitable for demanding industrial environments

The BI 2050 R6 NADELLA inner ring is particularly recommended where shaft hardening is not feasible or where maintenance strategies require replaceable raceway components instead of re-machining the shaft.

Why use an inner ring in a bearing assembly?

In many industrial systems, a needle roller bearing operates directly on the shaft. However, when the shaft material or surface finish does not meet bearing-grade requirements, an inner ring such as BI 2050 R6 provides a hardened raceway. This significantly increases system reliability, improves wear resistance, and enhances the overall lifespan of the bearing unit and housing assembly.
