Product Overview: The RN 205 Cylindrical Roller Bearing
The RN 205 is a high-capacity single-row Cylindrical Roller Bearing from our Without Inner Ring series. This specialized bearing is designed for applications where the shaft can be hardened and ground to serve as the inner raceway, offering a compact and rigid bearing solution. It is dimensionally designed to operate on a 25mm shaft, with an outer diameter of 52mm and a width of 15mm. By eliminating the inner ring, the RN 205 allows for a larger shaft diameter, increasing strength and rigidity, or a smaller housing bore, saving valuable radial space.
As a leading supplier of industrial parts, we provide RN 205 bearings manufactured to precise industry standards, ensuring reliable performance in high-load and high-speed environments. This design simplifies assembly and is ideal for compact machinery where maximizing shaft strength is critical. For applications requiring a complete bearing assembly, consider our standard NU 205 or NJ 205 cylindrical roller bearings.
Key Features of the RN 205 Bearing
- No Inner Ring Design: Allows the shaft to act as the raceway, enabling a more compact and space-saving design.
- High Radial Load Capacity: The line contact of cylindrical rollers provides excellent capacity for heavy radial loads.
- Separable Components: The outer ring and roller cage assembly can be mounted independently of the shaft, simplifying the installation process.
- Increased Shaft Strength: By using a larger shaft diameter in the same housing, this bearing enhances the overall rigidity and strength of the assembly.
- High-Speed Capability: Engineered for precision and low friction, making it suitable for high-speed rotational applications.
- Requires Prepared Shaft: For optimal performance and service life, the shaft raceway must be appropriately hardened and ground to specified tolerances.
Common Applications of RN 205 Bearings
- Automotive Transmissions: Used in gear sets where space is limited and high radial loads are present.
- Industrial Gearboxes: Provides robust support for gears and shafts in a compact footprint.
- Machine Tool Spindles: Contributes to the high rigidity required for precision cutting and milling operations.
- Connecting Rods: Suitable for internal combustion engine components where space and load capacity are critical factors.
- Planetary Gear Drives: Ideal for the compact and high-load environment of planetary gear systems.
- Pumps and Compressors: Supports rotating assemblies efficiently in various industrial fluid and gas handling equipment.
- Printing Machinery: Used in rollers and cylinders where precise and rigid support is necessary.
Benefits of Using the RN 205 Bearing
- Radial Space Savings: The absence of an inner ring significantly reduces the bearing's cross-section, ideal for compact designs.
- Improved System Rigidity: A larger, stronger shaft can be used within the same housing bore, leading to a stiffer and more robust assembly.
- Cost-Effective Solution: Can be more economical in applications where the shaft can be easily prepared to function as a raceway.
- Simplified Assembly and Maintenance: The separable design facilitates easier mounting, dismounting, and inspection of components.
- Enhanced Rotational Accuracy: Direct integration with a precision-ground shaft can lead to higher running accuracy.
- Design Flexibility: Offers engineers more options for creating compact, lightweight, and high-performance machinery.
