Product Overview: The NK 2016 Needle Roller Bearing
The NK 2016 is a high-capacity machined ring needle roller bearing with compact dimensions of 20x28x16mm (Bore x Outer Diameter x Thickness). As part of our NK Series, this bearing is designed without an inner ring, allowing it to run directly on a hardened and ground shaft. This configuration is ideal for applications where space is limited but high radial load capacity is essential. Its small cross-section makes it perfect for creating compact and lightweight machinery designs without compromising on strength and rigidity.
As a specialist supplier of industrial components, we provide top-quality Needle Roller Bearings that meet rigorous industry standards. The NK 2016's robust construction and precision engineering ensure reliable performance in demanding environments. Its design is particularly well-suited for applications requiring high rotational speeds and significant radial loads, making it a versatile solution for various industrial and automotive systems.

Key Features of the NK 2016 Bearing
- Compact and Lightweight: Features a small cross-sectional height, ideal for space-constrained applications.
- High Radial Load Capacity: The use of multiple small-diameter rollers provides a large contact area to support heavy radial loads.
- Designed Without Inner Ring: Runs directly on the shaft, which serves as the inner raceway, saving space and reducing component count.
- Rigid Machined Outer Ring: The solid, machined outer ring offers high rigidity and precision, suitable for demanding applications.
- Cage-Guided Rollers: Equipped with a cage that accurately guides the needle rollers, allowing for high-speed operation and reducing friction.
- Open-End Design: Suitable for applications where the shaft extends through the bearing housing.
Common Applications of NK 2016 Bearings
- Automotive Transmissions: Used in gear sets, clutches, and planetary gear systems where space is at a premium.
- Industrial Gearboxes: Provides robust support for gears and shafts in various industrial reduction units.
- Two-Stroke Engines: Commonly found in connecting rod and piston pin assemblies.
- Power Tools: Essential for the compact and high-speed mechanisms in drills, saws, and grinders.
- Pumps and Compressors: Supports rotating shafts in various fluid and air handling equipment.
- Textile and Printing Machinery: Ensures smooth and precise movement of rollers and shafts.
- Motorcycle Components: Used in swingarms, rocker arms, and transmission systems.
Benefits of Using the NK 2016 Bearing
- Space-Efficient Design: The absence of an inner ring allows for a larger shaft diameter or a smaller housing bore, optimizing the overall design.
- Enhanced Rigidity: Using a hardened shaft as the inner raceway creates a highly rigid and stable bearing arrangement.
- Cost-Effective Solution: Eliminates the cost and assembly time associated with a separate inner ring.
- Superior Performance: Capable of handling high speeds and heavy radial loads, improving machine efficiency and reliability.
- Reduced Friction and Heat: The cage design ensures optimal roller guidance, minimizing friction and extending the bearing's service life.
- Versatile Integration: Its standard dimensions allow for easy integration into a wide range of mechanical systems.
