ZVL NU 209 E Cylindrical Roller Bearing 45x85x19 mm

Premium Single-Row Cylindrical Roller Bearing with Increased Load Capacity

The ZVL NU 209 E 45x85x19 mm is a premium single-row cylindrical roller bearing engineered for applications requiring very high radial load capacity, excellent rigidity and reliable performance at high rotational speeds. The E designation indicates an optimized internal design with increased roller capacity, providing higher dynamic load ratings than the standard NU 209 design while maintaining identical boundary dimensions.

The NU design allows free axial displacement of the shaft relative to the housing in both directions, making the bearing ideal as a non-locating bearing where thermal expansion of shafts must be accommodated without generating internal stress. The separable inner and outer rings also simplify mounting and maintenance.

Applications

The ZVL NU 209 E is widely used in:

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

It is especially suitable for applications requiring high radial load capacity together with axial displacement compensation.

Construction and Design

Key design features include:

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

The NU configuration incorporates two integral flanges on the outer ring and no flanges on the inner ring, allowing unrestricted axial movement of the shaft while carrying heavy radial loads.

Material Properties

Manufactured from premium bearing steel, the bearing offers:

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