Product Overview: The RN 206 Cylindrical Roller Bearing Inner Ring
The RN 206 is a high-precision, separable inner ring designed for use with Cylindrical Roller Bearings. With standard dimensions of 30x50x19mm (Bore x Outer Diameter x Thickness), this component is engineered to provide a hardened and precision-ground raceway for roller elements directly on the shaft. It is an essential part for applications where it is impractical or uneconomical to harden and grind the shaft itself to act as a bearing raceway. The RN 206 is typically paired with an outer ring and roller assembly, such as the one found in an NU 206 bearing, to form a complete bearing unit.
As a key item in our Inner Rings collection, the RN 206 facilitates easier mounting and dismounting while allowing for axial displacement of the shaft relative to the housing. Its robust construction ensures reliable performance in demanding industrial environments, making it a versatile solution for various machinery. Explore our full range of bearing components to find the perfect fit for your application.
Key Features of the RN 206 Inner Ring
- Precision Ground Raceway: Offers a smooth, hardened surface for rollers, reducing friction and extending the life of the assembly.
- High-Quality Bearing Steel: Manufactured from premium-grade steel for exceptional durability, wear resistance, and load-carrying capacity.
- Separable Design: As an independent component, it simplifies the mounting and dismounting process, especially in tight spaces.
- Dimensional Stability: Heat-treated to ensure it maintains its shape and tolerances under heavy loads and high temperatures.
- Interchangeability: Made to strict industry standards, allowing for easy replacement and compatibility with corresponding roller and cage assemblies.
- Enables Axial Displacement: When used in an appropriate bearing arrangement, it can accommodate thermal expansion or contraction of the shaft.
Common Applications of RN 206
- Industrial Gearboxes: Provides a reliable raceway on gear shafts, supporting heavy radial loads.
