Product Overview: The NK 2420 Needle Roller Bearing
The NK 2420 is a high-performance needle roller bearing featuring a machined outer ring and a full complement of needle rollers, designed without an inner ring. With core dimensions of 24x36x20mm (Bore x Outer Diameter x Thickness), this bearing offers a compact and rigid solution for applications with high radial loads where space is limited. As part of our extensive NK Series, it is engineered to run directly on a hardened and ground shaft, which serves as the inner raceway. This design not only saves space but can also be a cost-effective solution for many industrial and automotive applications.
As a trusted supplier of mechanical components, we ensure our NK 2420 bearings meet stringent quality standards for reliable performance. This bearing is an excellent choice for arrangements that require high load-carrying capacity within a small radial footprint.

Key Features of the NK 2420 Bearing
- High Radial Load Capacity: The line contact of the needle rollers provides superior radial load-carrying capability compared to ball bearings of the same size.
- Compact & Space-Saving Design: Its low cross-sectional height makes it ideal for applications where radial space is a constraint.
- No Inner Ring: Designed to use the shaft as the inner raceway, allowing for a larger shaft diameter and increased rigidity.
- Machined Outer Ring: Provides high rigidity and dimensional accuracy, making it suitable for demanding applications.
- Cage-Guided Rollers: The cage ensures accurate guidance of the needle rollers, reducing friction, minimizing heat, and enabling higher operational speeds.
- Durable Construction: Manufactured from high-quality bearing steel to ensure long service life and resistance to wear under heavy loads.
Common Applications
- Industrial Gearboxes: Used in planetary gear sets and transmission systems where high torque and compact design are critical.
- Automotive Transmissions: Commonly found in automatic and manual transmissions, transfer cases, and engine components.
- Two-Stroke Engines: Ideal for connecting rods and crankshafts due to their high load capacity and compact size.
- Pumps and Compressors: Provides reliable support for rotating shafts in various types of pumps and industrial compressors.
- Power Tools: Used in professional-grade drills, saws, and grinders to handle high speeds and loads.
- Construction Machinery: Employed in hydraulic pumps, pivot pins, and other heavy-duty equipment.
- Office and Printing Equipment: Ensures smooth and precise movement in rollers and shafts.
Benefits of Using the NK 2420 Bearing
