Product Overview: The RN 222 Cylindrical Roller Bearing
The RN 222 is a single-row cylindrical roller bearing from our specialized Without Inner Ring series. With principal dimensions of 110mm (Fw) x 200mm (D) x 38mm (B), this bearing is engineered for applications where the shaft can be hardened and ground to serve as the inner raceway. This innovative design eliminates the need for a separate inner ring, resulting in a more compact radial cross-section and allowing for a larger, more robust shaft diameter. It is an ideal solution for space-constrained applications that require high radial load capacity and rigidity.
As a key component in our extensive range of Cylindrical Roller Bearings, the RN 222 provides a high-performance, space-saving alternative to conventional bearings. It is manufactured to precise industry standards to ensure reliable operation in demanding industrial environments. Explore similar bearings with inner rings like the N 222 and NU 222 for applications requiring a complete bearing assembly.
Key Features of the RN 222 Bearing
- Inner Ringless Design: Eliminates the inner ring, allowing rollers to run directly on a hardened shaft, which saves radial space.
- High Radial Load Capacity: The design is optimized to support heavy radial loads, making it suitable for heavy-duty machinery.
- Increased Shaft Diameter: By omitting the inner ring, a larger and stiffer shaft can be used without increasing the bearing's outer diameter.
- Enhanced Rigidity: The direct contact between rollers and the shaft provides a very rigid bearing arrangement.
- Separable Components: The outer ring and roller assembly can be mounted independently of the shaft, simplifying installation and maintenance.
- Precision Machining: Manufactured from high-quality bearing steel to ensure dimensional accuracy and smooth, reliable performance.
Common Applications
- Industrial Gearboxes: Used in transmission systems where space is limited but high load capacity is essential.
- Machine Tool Spindles: Provides the high stiffness required for precision cutting and grinding operations.
- Planetary Gear Sets: Ideal for the compact and high-load environment of planetary gear arrangements.
- Printing Machinery: Supports rollers and cylinders where a rigid and space-saving bearing is necessary.
- Automotive Transmissions: Employed in various powertrain components to handle high loads in a compact design.
- Rolling Mill Equipment: Suitable for support rollers in steel and metal processing where forces are substantial.
- Heavy Construction Equipment: Used in cranes, excavators, and other machinery requiring robust and durable rotating parts.
Benefits of Using the RN 222 Bearing
- Space-Saving Solution: The compact radial cross-section is perfect for designs where space is at a premium.
- Improved System Rigidity: Allows for a stronger, stiffer shaft, leading to less deflection and improved overall machine stability.
- Reduced Component Count: Simplifies the assembly by integrating the inner raceway into the shaft, reducing the number of parts.
- Cost-Effective Design: Can be a more economical choice for applications where the shaft is already suitable to act as a raceway.
- Simplified Assembly: The separable nature of the bearing facilitates easier mounting and dismounting procedures.
- High Performance: Delivers exceptional radial load support and operational reliability in challenging industrial settings.
