Product Overview: The RN 207 Cylindrical Roller Bearing
The RN 207 is a specialized cylindrical roller bearing designed without an inner ring. With nominal dimensions of 35mm for the shaft raceway, a 72mm outer diameter, and a 17mm width, this bearing is engineered for applications where the shaft can be hardened and ground to serve as the inner raceway. This innovative design allows for a larger shaft diameter relative to the bearing's outer diameter, increasing shaft rigidity and strength without increasing the overall housing size. As a component in our Cylindrical Roller Bearings collection, the RN 207 is ideal for creating compact, high-capacity, and rigid bearing arrangements.
This type of bearing consists of an outer ring with integral flanges that guide a roller and cage assembly. The absence of an inner ring makes it an excellent space-saving solution in industrial machinery. We ensure that every RN 207 bearing meets stringent quality standards, providing reliable performance for heavy radial loads and high-speed operation. Its separable design simplifies both the mounting and dismounting processes, making maintenance more efficient.
Key Features of the RN 207 Bearing
- Inner Ringless Design: Eliminates the inner ring, allowing the shaft to serve as the raceway for a more compact and rigid assembly.
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Space-Saving: Its compact cross-section is ideal for applications where radial space is limited.
- Separable Components: The outer ring and roller assembly can be mounted independently of the shaft, simplifying installation and inspection.
- Requires Hardened Shaft: Designed for use on shafts that are hardened and ground to precise specifications to ensure optimal performance and service life.
- Enhanced Shaft Rigidity: Enables the use of a larger, stiffer shaft within the same housing bore compared to bearings with an inner ring.
Common Applications of RN 207 Bearings
- Industrial Gearboxes: Used on gear shafts where a compact and high-load capacity bearing is essential.
- Machine Tool Spindles: Provides the rigidity and precision required for high-accuracy machining operations.
- Planetary Gear Sets: Ideal for the planet gears where space is minimal and load capacity needs are high.
