NKE NJ 215 E TVP3 Cylindrical Roller Bearing 75x130x25

Overview

The NKE NJ 215 E TVP3 is a premium single-row cylindrical roller bearing designed to support very high radial loads while also accommodating axial loads in one direction. The NJ design provides axial location of the shaft in one direction while allowing thermal expansion in the opposite direction, making it ideal for demanding industrial applications.

The bearing features an optimized E internal design, increasing load capacity, and a TVP3 glass fibre reinforced polyamide cage, which reduces friction, minimizes operating temperatures and ensures smooth, reliable operation at high speeds.

Manufactured by NKE Austria, this bearing is widely used in OEM equipment and industrial maintenance applications requiring high durability and precision.

Industrial Applications

The NJ 215 E TVP3 is commonly installed in:

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

Construction

The bearing incorporates:

• Single-row cylindrical rollers
• NJ design (two integral flanges on the outer ring and one flange 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 NJ configuration enables the bearing to carry heavy radial loads while locating the shaft axially in one direction.

Material

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

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

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

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