Product Overview: The N 312 Cylindrical Roller Bearing
The N 312 Cylindrical Roller Bearing is a high-performance component engineered to handle substantial radial loads at high speeds. With principal dimensions of 60x130x31mm (Bore x Outer Diameter x Thickness), this bearing is a key part of our N 300 Series within the broader Cylindrical Roller Bearings category. The 'N' designation signifies a design with two integral flanges on the inner ring and a flangeless outer ring. This configuration allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for accommodating thermal expansion or minor mounting inaccuracies.
As a leading supplier of industrial components, we ensure our N 312 bearings are manufactured to precise industry standards for reliability and longevity. The separable design, where the outer ring can be mounted independently of the inner ring and roller assembly, greatly simplifies both installation and maintenance procedures in complex machinery.
Key Features of the N 312 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows the bearing to support heavy radial loads.
- Axial Displacement Capability: Accommodates thermal expansion and contraction of the shaft by allowing it to move axially within the housing.
- Separable Design: The inner ring with the roller and cage assembly can be mounted separately from the outer ring, facilitating easier installation and inspection.
- High Stiffness: Provides a high degree of rigidity, making it suitable for applications requiring precise shaft support.
- Low Friction Operation: Engineered with an optimized internal geometry to minimize friction, reduce operating temperatures, and enhance efficiency.
- Robust Construction: Manufactured from high-quality bearing steel for exceptional durability and resistance to wear under demanding conditions.
Common Applications of N 312 Bearings
- Industrial Gearboxes: Provides rigid and reliable support for gears and shafts, ensuring smooth power transmission.
- Electric Motors: Used in large electric motors to support the rotor shaft and handle significant radial forces.
- Pumps and Compressors: Essential for supporting rotating shafts in industrial pumping and compression equipment.
- Construction and Mining Equipment: Ideal for heavy-duty machinery where high radial loads are common.
- Rolling Mills: Employed in steel and metal processing to support the rollers under extreme pressure.
- Machine Tool Spindles: Offers the precision and stiffness required for high-accuracy machining operations.
- Vibrating Screens and Shakers: Withstands the heavy, shock-like radial loads found in material processing equipment.
Benefits of Using the N 312 Bearing
