NU316 M/C3 ISB cylindrical roller bearing

ISB NU316 M/C3 Single Row Cylindrical Roller Bearing

The ISB NU316 M/C3 is a high-performance component engineered to withstand extreme radial loads. The NU type design features two integral flanges on the outer ring, while the inner ring is smooth, allowing for axial displacement of the shaft relative to the housing. This is vital for compensating thermal expansion in large motors and turbines. The use of a machined brass cage (M) and increased C3 internal clearance ensures reliability under severe vibrations and high operating temperatures.

Application

• Heavy-duty Electric Motors: Support for the non-locating (floating) side of shafts in high-power drives.
• Industrial Gearboxes: Reliable operation in nodes with very high radial stress.
• Pumps and Compressors: Stable performance at high rotational speeds and fluctuating temperatures.
• Power Plants and Turbines: Durability in systems requiring high precision and dynamic resistance.
• Steel and Paper Mills: Supporting rollers and shafts operating under continuous heavy pressure.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: NU316 M/C3
• Type: Single row cylindrical roller bearing
• Design: NU type (axially free, separable).
• Cage: M – Machined brass (roller-centered).
• Internal Clearance: C3 – increased radial clearance.

Note: Standard dimensions for the NU316 are 80 mm (Bore) × 170 mm (OD) × 39 mm (Width).

Features and Benefits

• Superior Radial Load Capacity: Linear contact between rollers and raceways supports significantly higher forces than ball bearings.
• Thermal Expansion Compensation: The NU design eliminates axial stress caused by system heat buildup.
• Brass Cage (M): Offers excellent lubricating properties and high fatigue resistance, critical for high-speed duty.
• C3 Clearance: Provides a safe operating margin, preventing bearing seizure during significant temperature rises.
• Separable Design: Facilitates independent mounting of the inner and outer rings on the shaft and housing.

Why Choose This Product

The ISB NU316 M/C3 bearing is a professional choice for the most demanding bearing nodes. Combining Italian engineering precision with the robustness of a brass cage, this product drastically reduces the risk of sudden failures in critical industrial machinery. By choosing ISB, you invest in a component with high operational standards, ensuring stable technological processes and a long service life under extreme mechanical stress.
