NU320 ECM SING ISB cylindrical roller bearing

ISB NU320 ECM Cylindrical Roller Bearing (SING)

The ISB NU320 ECM is a heavy-duty single-row cylindrical roller bearing engineered for extreme radial load capacities. The NU type design features two integral ribs on the outer ring and a smooth inner ring without ribs. This configuration allows for free axial displacement of the shaft in both directions, making it an essential non-locating bearing that eliminates stresses caused by the thermal expansion of shafts.

Application

• Industrial Gearboxes: Handling massive radial forces in heavy-duty drive systems.
• High-Power Electric Motors: Supporting large-diameter rotors in industrial units.
• Industrial Pumps and Fans: Reliable performance in continuous high-speed operations.
• Machine Tools: Providing maximum radial stiffness for precision drives.
• Mining Equipment: Exceptional vibration resistance for crushers and screening machines.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: NU320 ECM
• Type: Single-row cylindrical roller bearing.
• Cage: ECM – Machined brass cage, roller centered.
• Axial Compensation: Yes (non-locating design).
• Packaging: SING (Single unit packaging).

Note: Standard dimensions for the NU320 are 100 mm (Bore) × 215 mm (OD) × 47 mm (Width).

Features and Benefits

• Extreme Radial Capacity: The line contact between rollers and raceways offers significantly higher load ratings compared to ball bearings.
• Machined Brass Cage (ECM): Provides superior roller guidance, high thermal stability, and excellent damping of mechanical vibrations.
• Thermal Expansion Relief: The NU design prevents system jamming by allowing the shaft to expand axially as it heats up.
• High Speed Capability: Precision-engineered raceways support high rotational speeds with minimal heat buildup.
• Premium Durability: Manufactured from high-purity bearing steel to resist material fatigue and ensure a long service life.
