Product Overview: The NU 316 Cylindrical Roller Bearing
The NU 316 is a high-capacity, single-row cylindrical roller bearing engineered to handle heavy radial loads at high speeds. With principal dimensions of 80mm bore diameter, 170mm outer diameter, and 39mm thickness, this bearing is a robust component in our Cylindrical Roller Bearings collection. The defining feature of the NU design is its separable inner ring; the outer ring has two integral flanges, while the inner ring is flangeless. This configuration allows for free axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion.
As part of the versatile NU 300 Series, the NU 316 is manufactured to exacting industry standards, ensuring reliable performance and longevity in demanding industrial environments. Its design simplifies mounting and dismounting procedures, making it a practical choice for a wide range of machinery.

Key Features of the NU 316 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial forces.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, facilitating easy installation and maintenance.
- Axial Displacement Accommodation: The NU design allows the shaft to move axially relative to the housing, compensating for thermal expansion or contraction.
- High-Speed Performance: Engineered with an optimized internal geometry to minimize friction and support high rotational speeds.
- Durable Construction: Manufactured from premium-grade bearing steel for exceptional hardness, wear resistance, and long service life.
- Interchangeability: Produced to standard dimensions, allowing for easy replacement and interchangeability with other manufacturers' parts.
