NK 15/12 ZEN 15x23x12 Needle Bearing

Main Description

The NK 15/12 ZEN 15x23x12 Needle Bearing is a compact, high-strength rolling element designed for machinery that demands excellent radial load capacity within minimal installation space. With dimensions 15x23x12 mm, it is ideal for gear systems, industrial drives, transport mechanisms, agricultural equipment and other industrial applications where reliability and durability are essential.

Needle bearings of the NK series contain numerous small-diameter rollers that distribute load efficiently, allowing the bearing to carry significantly higher radial forces compared to standard ball bearings of similar size. The NK 15/12 ZEN operates with low friction and maintains stability even under dynamic and pulsating loads, making it suitable for intensive continuous-duty conditions.

Its precise needle geometry and hardened raceway surfaces ensure long service life, minimal wear and smooth operation. Because this design typically does not include an inner ring, it works in combination with a hardened shaft or can be integrated into bearing housings and bearing units that require compact, high-performance components. This makes it an excellent choice for equipment designers seeking maximum load capacity without increasing system weight.

Key Advantages

• durable needle bearing optimized for high radial loads

• compact size for installations with limited space

• stable, low-friction operation under dynamic load conditions

• suitable for gearboxes, drives, agricultural and transport machinery

• long service life ensured by precise needle and raceway construction

The NK 15/12 ZEN is a dependable, cost-effective solution for industrial equipment requiring high load capacity and long-term reliability.

FAQ - Frequently Asked Questions

Q: What are the dimensions of the NK 15/12 ZEN needle bearing?
A: 15 mm inner diameter, 23 mm outer diameter, 12 mm width.

Q: Where is this bearing typically used?
A: In gear drives, conveyor systems, agricultural machinery, industrial automation and compact motion assemblies.

Q: Does it require a hardened shaft?
A: Yes - NK-type bearings usually run directly on a hardened and ground shaft surface.

Q: Is this bearing suitable for high radial loads?
A: Yes, handling high radial forces is the primary function of NK-series needle bearings.

Q: Is it designed for high-speed rotation?
A: It can operate at moderate speeds, but its main advantage is high load capacity rather than maximum speed.
