NKE NJ 211 E TVP3 Cylindrical Roller Bearing 55x100x21

Overview

The NKE NJ 211 E TVP3 is a premium single-row cylindrical roller bearing designed to withstand high radial loads while supporting axial loads in one direction. The NJ design locates the shaft axially in one direction while permitting thermal expansion in the opposite direction, making it ideal for gearbox, motor and industrial machinery applications.

The bearing features an optimized E internal design, increasing load capacity compared to standard designs, together with a TVP3 glass fibre reinforced PA66 polyamide cage, which reduces friction, lowers operating temperatures and enables reliable operation at high rotational speeds.

Industrial Applications

The NJ 211 E TVP3 is widely used in:

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

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 higher load capacity
• TVP3 glass fibre reinforced PA66 polyamide cage
• Open bearing design
• Cylindrical bore
• Separable construction for simplified mounting and maintenance

The NJ configuration enables high radial load carrying capacity while providing axial shaft location in one direction.

Material
