Product Overview: The NK 2020 Needle Roller Bearing
The NK 2020 is a high-capacity machined ring needle roller bearing, designed with key dimensions of 20x28x20mm (Bore x Outer Diameter x Thickness). As part of our extensive NK Series, this bearing belongs to the family of Machined Ring Bearings without an inner ring. Its design is ideal for applications where the shaft can be hardened and ground to serve as the raceway, offering a highly compact and rigid bearing arrangement. The robust machined outer ring ensures high radial load capacity and shock resistance within a minimal cross-section.
The NK 2020 is engineered for superior performance in demanding industrial environments where space is a critical constraint. As a leading supplier, we provide top-quality Needle Roller Bearings that meet strict industry standards, ensuring reliability and long service life. This bearing is a preferred choice for engineers seeking to minimize component size without sacrificing load-carrying capability.
Key Features of the NK 2020 Bearing
- High Radial Load Capacity: The full complement of needle rollers provides exceptional load-bearing capability in a small footprint.
- Compact and Rigid Design: Features a low cross-sectional height, making it perfect for space-constrained applications.
- No Inner Ring: Designed to run directly on a hardened and ground shaft, allowing for a larger shaft diameter and increased rigidity.
- Machined Outer Ring: The solid, channel-shaped outer ring provides high stability and is suitable for heavy-duty applications.
- Cage-Guided Rollers: The cage ensures uniform roller spacing for reduced friction, lower heat generation, and suitability for higher speeds.
- Enhanced Lubrication: The open design facilitates effective lubrication, which is crucial for extending the bearing's operational life.
Common Applications of NK 2020 Bearings
- Automotive Transmissions: Used in gear sets, planetary gears, and shafts where space and load capacity are critical.
- Industrial Gearboxes: Provides robust support for gears and shafts in various industrial reduction units.
- Pumps and Compressors: Ideal for connecting rods, piston pins, and crankshafts that experience high radial loads.
- Two-Stroke Engines: Commonly found in small-end and big-end connecting rod applications.
- Power Tools: Used in professional-grade drills, saws, and grinders to handle high speeds and loads compactly.
- Construction and Agricultural Machinery: Suitable for pivot points and linkages in heavy equipment.
- Material Handling Equipment: Employed in conveyor rollers and other components requiring reliable, compact bearings.
Benefits of Using the NK 2020 Bearing
- Space-Saving Arrangement: Eliminates the need for a separate inner ring, enabling more compact and lightweight machinery designs.
- Increased Shaft Strength: By allowing for a larger shaft diameter, it contributes to a stronger and more rigid overall assembly.
- Cost-Effective Solution: Using the shaft as the inner raceway can reduce the total number of components and lower assembly costs.
- Superior Performance: The precision-machined outer ring and guided rollers ensure smooth, reliable operation even under heavy loads and high speeds.
- Reduced Maintenance: High-quality construction and design lead to longer service intervals and increased machine uptime.
- High Operational Accuracy: The rigidity of the bearing assembly helps maintain precise shaft alignment and positioning.
