ZVL NU 305 E Cylindrical Roller Bearing 25x62x17 mm

Premium Single-Row Cylindrical Roller Bearing with Increased Load Capacity

The ZVL NU 305 E 25x62x17 mm is a premium single-row cylindrical roller bearing designed for applications requiring very high radial load capacity and excellent performance at high rotational speeds. The E designation indicates an optimized internal design with a higher number or optimized arrangement of rollers, providing increased load-carrying capacity compared to the standard NU 305 design while maintaining identical external dimensions.

The NU design allows axial displacement of the shaft relative to the housing in both directions, making the bearing ideal as a non-locating bearing in machinery where thermal expansion of the shaft must be accommodated. The separable inner and outer rings also simplify installation and maintenance.

Applications

The ZVL NU 305 E is widely used in:

• Industrial gearboxes
• Electric motors
• Industrial pumps
• Machine tools
• Compressors
• Industrial fans
• Power transmission systems
• Agricultural machinery
• Mining equipment
• Heavy industrial machinery

It is particularly suitable for applications requiring high radial load capacity and compensation of thermal shaft expansion.

Construction and Design

Key design features include:

• Single-row cylindrical roller bearing
• NU design
• Optimized E internal design
• Open bearing construction
• Steel cage
• High radial load capacity
• High-speed capability
• Precision-ground raceways
• Separable inner and outer rings

The NU configuration features two integral flanges on the outer ring and no flanges on the inner ring, allowing free axial movement of the shaft relative to the housing while carrying heavy radial loads.

Material Properties

Manufactured from premium bearing steel, the bearing provides:

• Outstanding wear resistance
• Excellent fatigue strength
• Very high radial load capacity
• High rigidity
• Excellent dimensional stability
• Low rolling resistance
• Long operational service life
• Reliable performance under heavy-duty conditions
