Product Overview: The NK 2216 Needle Roller Bearing
The NK 2216 is a high-capacity machined ring needle roller bearing with dimensions of 22x30x16mm. As part of our NK Series, this bearing is designed without an inner ring, making it an excellent solution for applications where the shaft can be hardened and ground to serve as the raceway. This design provides a very compact and space-saving bearing arrangement capable of supporting heavy radial loads. Belonging to our extensive range of Needle Roller Bearings, the NK 2216 is engineered for rigidity and precision.
This bearing's robust construction features a machined and ground outer ring with a cage that securely guides the needle rollers. This ensures optimal performance, reduced friction, and suitability for high-speed applications. It is an ideal component for compact machinery designs where radial space is minimal but load-carrying capacity cannot be compromised.

Features of the NK 2216 Bearing
- Space-Saving Design: The absence of an inner ring provides an extremely low cross-sectional height.
- High Radial Load Capacity: Needle rollers offer a large contact area, enabling the bearing to handle significant radial forces.
- Machined Outer Ring: Provides high rigidity and allows for a tight press fit into the housing.
- Cage-Guided Rollers: The cage ensures uniform roller spacing, reduces friction, prevents roller skewing, and allows for higher operational speeds.
- Direct Shaft Mounting: Designed to run directly on a hardened and ground shaft, simplifying the overall design and reducing component count.
- Precision Engineering: Manufactured to tight tolerances for reliable and consistent performance in demanding applications.
Applications of NK 2216 Bearings
- Industrial Gearboxes: Used for supporting planetary gears and shafts in compact transmission systems.
- Automotive Transmissions: Ideal for use in gear sets, clutches, and driveshafts where space is limited.
- Two-Stroke Engines: Commonly found in connecting rod and piston pin applications.
- Power Tools: Provides robust support for rotating components in drills, saws, and grinders.
- Construction Equipment: Suitable for hydraulic pumps, motors, and pivot points in heavy machinery.
- Office Machines: Used in printers, copiers, and other equipment requiring precise and compact rotational support.
- Textile Machinery: Ensures smooth operation of various rollers and shafts in processing equipment.
