Product Overview: The NJ 304 Cylindrical Roller Bearing
The NJ 304 is a high-performance single-row cylindrical roller bearing, engineered to support heavy radial loads and high-speed operation. With principal dimensions of 20x52x15mm, this bearing is a key component in our NJ 300 Series. Its design is part of the broader Cylindrical Roller Bearings category, known for their exceptional load-carrying capacity and rigidity. The NJ designation signifies that it has two integral flanges on the outer ring and one on the inner ring, allowing it to locate the shaft axially in one direction. This feature is crucial for applications requiring precise shaft positioning under load.
As a specialist supplier of industrial components, we ensure that our NJ 304 bearings meet stringent quality standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies both installation and maintenance procedures. This makes the NJ 304 a reliable and practical choice for a wide array of demanding industrial environments.
Features of the NJ 304 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Load in One Direction: Features an integral flange on one side of the inner ring, enabling it to accommodate axial loads and locate the shaft in a single direction.
- Separable Design: The inner ring is separable, which simplifies mounting and dismounting processes, especially in tight-fit applications.
- High-Speed Performance: Engineered with low-friction characteristics, making it suitable for applications with high rotational speeds.
- Robust Construction: Manufactured from premium-grade bearing steel for superior durability, wear resistance, and extended service life.
- Dimensional Stability: Precision-engineered to maintain its shape and performance under heavy loads and high temperatures.
