Product Overview: The N 311 Cylindrical Roller Bearing
The N 311 bearing is a high-capacity, single-row cylindrical roller bearing with dimensions of 55x120x29mm. As part of our N 300 Series, this bearing is specifically engineered to handle heavy radial loads at high speeds. Its 'N' design signifies that it is a non-locating bearing; the inner ring is separable and can move axially in either direction relative to the outer ring. This feature is crucial for applications accommodating thermal expansion or contraction of the shaft, preventing induced axial stresses.
Manufactured from premium-grade bearing steel, the N 311 provides exceptional durability and performance in demanding industrial environments. The line contact between the rollers and raceways ensures optimal load distribution and rigidity. For comprehensive solutions, explore our full range of Cylindrical Roller Bearings.
Features of the N 311 Bearing
- High Radial Load Capacity: Line contact geometry allows for the accommodation of very heavy radial loads.
- Non-Locating Design: The inner ring can be displaced axially relative to the outer ring, compensating for shaft expansion.
- Separable Components: The inner ring can be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance procedures.
- High-Speed Performance: Engineered with low-friction characteristics, making it suitable for applications with high rotational speeds.
- Robust Construction: Made from high-quality, clean bearing steel to ensure a long operational lifespan and reliability.
- Precision Machining: Manufactured to strict tolerances for consistent and smooth operation.
Applications of N 311 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts under significant radial stress.
- Electric Motors: Used in large motors where high radial load capacity is essential for the rotor shaft.
- Pumps and Compressors: Ensures reliable operation of rotating components in heavy-duty fluid machinery.
