Product Overview: The HK 2520 Drawn Cup Needle Roller Bearing
The HK 2520 is a high-performance drawn cup needle roller bearing featuring a bore diameter of 25mm, an outer diameter of 32mm, and a width of 20mm (25x32x20mm). This component belongs to our extensive range of Needle Roller Bearings and is specifically an Open End Drawn Cup Bearing. Its unique design consists of a thin-walled, drawn outer cup and a needle roller and cage assembly, providing a very low sectional height. This makes the HK 2520 an excellent solution for compact and lightweight designs where radial space is limited but high load-carrying capacity is essential.
As a leading supplier of industrial bearings, we ensure our HK 2520 bearings are manufactured to precise industry standards. This bearing is designed to be press-fitted into the housing, which means the housing bore can be used as the raceway, eliminating the need for a separate inner ring in many cases and further saving space and cost. This design is ideal for applications requiring robust performance in a minimal footprint.
Key Features of the HK 2520 Bearing
- Low Cross-Section: Its minimal radial height makes it perfect for applications with limited space.
- High Radial Load Capacity: Despite its compact size, the full complement of needle rollers provides excellent load-carrying capability.
- Drawn Cup Outer Ring: The thin, pressed-steel outer ring offers a cost-effective and lightweight bearing solution.
- Open-End Design: Allows for shafts to pass through the bearing, suitable for various mounting configurations.
- Press-Fit Installation: Simplifies assembly, as the bearing is securely mounted by pressing it into the housing bore.
- Cage-Guided Rollers: The cage ensures proper roller guidance, making it suitable for higher speed applications and reducing friction.
Common Applications of HK 2520 Bearings
- Automotive Systems: Widely used in transmissions, steering systems, and engine components like rocker arms.
- Power Tools: Essential in drills, sanders, and other handheld equipment where space and weight are critical.
- Industrial Gearboxes: Provides reliable support for gears and shafts in compact gearbox designs.
- Office and Household Appliances: Found in printers, copiers, and other appliances requiring smooth rotational motion.
- Two-Stroke Engines: Used for connecting rods and crankshafts in small engines.
- Conveyor Rollers: Offers a compact and durable solution for material handling systems.
- Agricultural Machinery: Suitable for various pivot points and linkage applications in farm equipment.
Benefits of Using the HK 2520 Bearing
- Space Efficiency: The extremely low sectional height allows for downsizing of machinery and components.
- Reduced Weight: The lightweight drawn cup design helps minimize the overall weight of the application.
- Cost-Effective: Its simple construction and the ability to run directly on a hardened shaft make it an economical choice.
- Simplified Housing Design: The press-fit installation eliminates the need for shoulders or snap rings in the housing, reducing manufacturing complexity.
- Enhanced Performance: Offers high rigidity and load capacity, contributing to the reliability and longevity of the machinery.
- Versatile Mounting: The open-end design provides flexibility in shaft and housing arrangements.
