NKE NU 211 E TVP3 Cylindrical Roller Bearing 55x100x21

Overview

The NKE NU 211 E TVP3 is a premium single-row cylindrical roller bearing engineered for applications requiring high radial load capacity, excellent rigidity and high operating speeds. The NU design allows axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing arrangements.

Manufactured by NKE Austria, this bearing features an optimized E internal design for increased load capacity and a TVP3 glass fibre reinforced polyamide cage, providing low friction, reduced operating temperatures and extended service life.

Industrial Applications

The NU 211 E TVP3 is widely used in:

• Industrial gearboxes
• Electric motors
• Pumps and compressors
• Machine tools
• Industrial transmissions
• Conveyor systems
• Agricultural machinery
• Mining equipment
• General industrial machinery

Construction

The bearing incorporates:

• Single-row cylindrical rollers
• NU design (two flanges on the outer ring, no flanges on the inner ring)
• Optimized E internal geometry for higher load capacity
• TVP3 glass fibre reinforced PA66 polyamide cage
• Open bearing design
• Cylindrical bore
• Separable construction for simplified installation and maintenance

The NU design enables axial displacement of the shaft in both directions while carrying high radial loads.

Material

The bearing is manufactured from premium bearing steel with:

• Through-hardened raceways
• Precision-ground rolling surfaces
• High fatigue resistance
• Excellent wear resistance
• High dimensional stability
• Long service life under demanding operating conditions

The TVP3 cage is manufactured from glass fibre reinforced polyamide PA66, combining low weight with excellent mechanical strength and low friction.
