Product Overview: The NK 1216 Needle Roller Bearing
The NK 1216 is a high-performance machined ring Needle Roller Bearing with dimensions of 12x20x16mm. As part of our NK Series, this bearing is designed Without Inner Ring, allowing it to use a hardened and ground shaft as the inner raceway. This design offers a highly compact and rigid bearing arrangement, making it ideal for applications where radial space is limited but high load-carrying capacity is essential. The robust machined outer ring ensures superior performance under heavy radial loads and demanding conditions.
Engineered for precision, the NK 1216 provides excellent rotational accuracy and is suitable for a wide range of industrial machinery and automotive applications. Its caged needle rollers are optimized for high speeds and ensure consistent, reliable operation. For applications where the shaft cannot be used as a raceway, this bearing can be combined with an IR 12*16*16 inner ring.
Key Features of the NK 1216 Bearing
- Compact Radial Profile: The absence of an inner ring provides an extremely low cross-sectional height, saving valuable space.
- High Radial Load Capacity: Features a full complement of needle rollers that offer maximum contact, enabling it to support heavy radial loads.
- Machined Outer Ring: A solid, channel-shaped outer ring provides high rigidity and strength, suitable for robust applications.
- Cage-Guided Rollers: The cage ensures precise guidance of the needle rollers, allowing for higher speed capabilities and reduced friction compared to full complement designs.
- Shaft as Raceway: Designed to run directly on a hardened and ground shaft, creating a cost-effective and space-saving bearing solution.
- Versatile Compatibility: Can be paired with an appropriate IR series inner ring if the shaft is not hardened.
Common Applications
- Automotive Transmissions: Used in gearboxes and clutch assemblies where space is tight and loads are high.
- Industrial Gearboxes: Provides reliable support for gears and shafts in various industrial reduction units.
- Two-Stroke Engines: Ideal for connecting rod and piston pin applications due to its compact size and high strength.
- Power Tools: Incorporated into drills, saws, and grinders to handle high-speed rotational forces.
- Printing and Textile Machinery: Ensures smooth and precise movement of rollers and other critical components.
- Pumps and Compressors: Supports rotating shafts, ensuring efficiency and durability in fluid and air handling systems.
- Material Handling Equipment: Used in conveyor rollers and pivot points that require robust radial support.
Benefits of Using the NK 1216 Bearing
- Space and Weight Savings: Its compact design without an inner ring reduces both the required mounting space and the overall weight of the assembly.
- Enhanced Rigidity: The solid machined outer ring provides superior stiffness and minimizes deflection under load.
- Improved Operational Efficiency: The cage-guided rollers minimize friction, leading to smoother operation and reduced energy consumption.
- Cost-Effective Design: Eliminates the expense of a separate inner ring when the application's shaft can be suitably prepared.
- Increased Durability: Constructed from high-quality bearing steel, it offers excellent wear resistance and a long service life.
- High-Speed Performance: The cage assembly allows the bearing to operate reliably at higher rotational speeds than uncaged designs.
