Product Overview: The N 217 Cylindrical Roller Bearing
The N 217 bearing is a high-performance cylindrical roller bearing with dimensions of 85x150x28mm, designed to handle high radial loads at high rotational speeds. As a key component in our Cylindrical Roller Bearings category, it belongs to the versatile N 200 Series. The N-type design features two integral flanges on the inner ring and a flangeless outer ring, allowing the bearing to accommodate axial displacement of the shaft relative to the housing in one direction. This feature is critical in applications where thermal expansion or mounting inaccuracies can occur.
Manufactured to exacting industry standards, the N 217 offers exceptional reliability and a long service life in demanding industrial environments. Its line contact geometry between the rollers and raceways provides superior load distribution, preventing stress concentrations and ensuring smooth, efficient operation. This makes it an ideal choice for machinery requiring robust and precise rotational support.
Key Features of the N 217 Bearing
- High Radial Load Capacity: Engineered with a single row of cylindrical rollers, providing excellent capacity for heavy radial forces.
- Axial Displacement Capability: The N-type design allows for axial movement of the shaft in one direction, compensating for thermal expansion.
- Separable Design: The inner ring can be separated from the outer ring and roller assembly, simplifying the mounting and dismounting process.
- High-Speed Performance: Optimized internal geometry reduces friction and heat generation, making it suitable for high-speed applications.
- Robust Construction: Made from high-quality bearing steel for enhanced durability, wear resistance, and operational longevity.
- Line Contact Geometry: Ensures uniform stress distribution along the contact length, reducing edge stresses and increasing bearing life.
Common Applications of N 217 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial loads typical in power transmission systems.
- Electric Motors: Used as a non-locating bearing to support motor shafts, accommodating axial movement while carrying heavy radial loads.
- Pumps and Compressors: Ensures smooth and efficient rotation of shafts in various types of industrial pumps and compressors.
- Machine Tool Spindles: Delivers the high rigidity and rotational accuracy required for precision machining operations.
- Construction and Mining Equipment: Withstands the harsh conditions and heavy loads found in machinery like excavators, loaders, and crushers.
- Rolling Mills: Used in steel and metal processing machinery where high loads and speeds are common.
- Vibrating Screens: Offers the durability needed to operate reliably in high-vibration applications.
Benefits of Using the N 217 Bearing
- Enhanced Machine Reliability: High load capacity and robust design lead to fewer breakdowns and increased machine uptime.
- Simplified Maintenance: The separable design allows for easier inspection, lubrication, and replacement, reducing maintenance time and costs.
- Improved Operational Efficiency: Low friction characteristics contribute to reduced energy consumption and cooler operation.
