NKE NU 215 E TVP3 Cylindrical Roller Bearing 75x130x25

Overview

The NKE NU 215 E TVP3 is a premium single-row cylindrical roller bearing engineered to support very high radial loads while allowing unrestricted axial displacement of the shaft relative to the housing. The NU design functions as a non-locating bearing, effectively compensating for thermal expansion and preventing unwanted internal stresses in industrial machinery.

The bearing incorporates an E optimized internal design, featuring an increased number and optimized arrangement of rollers to maximize load capacity. It also utilizes a TVP3 glass fibre reinforced PA66 polyamide cage, which minimizes friction, reduces operating temperatures and ensures smooth, reliable operation at high rotational speeds.

Manufactured by NKE Austria, this bearing is widely trusted in OEM equipment and demanding industrial maintenance applications.

Industrial Applications

The NU 215 E TVP3 is commonly used in:

• Industrial gearboxes
• Electric motors
• Pumps
• Compressors
• Machine tools
• Conveyor systems
• Agricultural machinery
• Mining equipment
• Heavy-duty transmission systems
• General industrial machinery

Construction

The bearing features:

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

The NU design allows axial shaft movement in both directions while transmitting heavy radial loads, making it ideal for floating bearing arrangements.

Material

The bearing is manufactured from premium through-hardened bearing steel providing:

• High fatigue strength
• Excellent wear resistance
• Precision-ground raceways
• High dimensional stability
• Long operating life
• Reliable performance under continuous industrial operation

The TVP3 cage is manufactured from glass fibre reinforced PA66 polyamide, offering:

• Low weight
• High mechanical strength
• Low friction
• Quiet operation
• Excellent resistance to dynamic loads
