Product Overview: HK 4020 Drawn Cup Needle Roller Bearing
The HK 4020 is a high-performance drawn cup needle roller bearing, designed with dimensions of 40x47x20mm (Bore x Outer Diameter x Thickness). This component is a key part of our Needle Roller Bearings collection and is specifically categorized under Open End Drawn Cup Bearings. Its unique construction features a thin-walled, drawn cup outer ring and a needle roller and cage assembly, making it an excellent choice for applications with limited radial space that still require high load-carrying capacity. The open-end design is suitable for through-shaft applications and provides a cost-effective, space-saving solution for various industrial and automotive needs.
Key Features of the HK 4020 Bearing
- Compact and Lightweight: The drawn steel outer cup provides a very low cross-sectional height, saving space and reducing overall machine weight.
- High Radial Load Capacity: Despite its compact size, the full complement of needle rollers allows it to handle significant radial loads.
- Open-End Design: Suitable for applications where the shaft extends through the housing on both sides.
- Press-Fit Installation: Designed for a tight press fit into the housing, which forms the outer raceway shape and ensures secure mounting.
- Cost-Effective Solution: Offers excellent performance and high load capacity at an economical price point compared to machined ring bearings.
- Shaft as Raceway: Utilizes a hardened and ground shaft as the inner raceway, simplifying the overall design and reducing the number of components.
Common Applications
- Automotive Systems: Widely used in transmissions, gear pumps, clutches, and steering mechanisms.
- Power Tools: Ideal for drills, saws, and sanders where space is limited and high rotational speeds are common.
- Industrial Gearboxes: Provides robust support for gear sets in compact industrial machinery.
- Two-Stroke Engines: Commonly found in connecting rods and piston pin applications.
- Pumps and Compressors: Ensures reliable operation of rotating shafts within compact pump and compressor designs.
- Office and Domestic Appliances: Used in printers, copiers, and other equipment requiring precise and compact rotational motion.
- Agricultural Machinery: Suitable for various components in farming equipment that operate under heavy loads.
Benefits of Using the HK 4020 Bearing
- Space Efficiency: Its minimal radial footprint allows for more compact and streamlined machinery design.
- Reduced Weight: The thin-walled construction contributes to lighter final products, improving efficiency, particularly in automotive applications.
- Enhanced Rigidity: When properly installed, it provides a rigid bearing arrangement, ensuring stable and precise shaft rotation.
- Simple and Secure Mounting: The press-fit installation method is straightforward and eliminates the need for shoulders or snap rings in the housing bore.
- Improved Performance: Low friction and high rotational speed capabilities lead to more efficient and reliable machinery operation.
- Economic Advantage: Offers a high-performance bearing solution without the higher cost associated with heavier, machined-ring bearings.
