Product Overview: The HK 1212 Drawn Cup Needle Roller Bearing
The HK 1212 is a compact and efficient needle roller bearing, featuring key dimensions of a 12mm bore diameter, 18mm outer diameter, and 12mm width. This bearing is a prominent member of our Drawn Cup Bearings collection, which falls under the broader category of Needle Roller Bearings. Its design incorporates a thin-walled, drawn outer cup that serves as the raceway for the needle rollers. This construction makes the HK 1212 exceptionally suitable for applications where radial space is limited but a high load-carrying capacity is required. Installation is straightforward, as the bearing is designed to be press-fitted into the housing, eliminating the need for complex mounting hardware like snap rings or shoulders.
Key Features of the HK 1212 Bearing
- Compact and Lightweight: The thin-walled drawn cup design provides a very small cross-section, saving space and reducing overall weight.
- High Radial Load Capacity: Despite its small size, the full complement of needle rollers allows it to handle significant radial loads.
- Press-Fit Installation: Designed for a tight interference fit in the housing, which simplifies assembly and provides a rigid mounting solution.
- Open-End Design: The open-end construction is suitable for through-shaft applications and facilitates lubrication.
- Cost-Effective: An economical choice for high-volume production and applications where space and cost are primary concerns.
- Precision Engineering: Manufactured to strict tolerances to ensure reliable and consistent performance in demanding machinery.
Common Applications
- Automotive Systems: Widely used in transmissions, gear pumps, alternators, and steering mechanisms.
- Power Tools: Ideal for use in drills, saws, and other handheld equipment where space is at a premium.
- Industrial Gearboxes: Provides robust support for gears and shafts in compact industrial machinery.
- Two-Stroke Engines: Commonly used for piston pins and connecting rods due to its high performance in oscillating conditions.
- Office Equipment: Found in printers, copiers, and fax machines, ensuring smooth roller movement.
- Pumps and Compressors: Supports rotating shafts in various types of pumps and small compressors.
- Household Appliances: Used in various appliances that require reliable rotational motion in a compact form factor.
Benefits of Using the HK 1212 Bearing
- Space Efficiency: Enables smaller and more lightweight product designs without sacrificing load capacity.
- Simplified Housing Design: The press-fit installation means the housing bore can be used as the outer raceway, reducing component count and machining costs.
- Enhanced Rigidity: Forms a rigid and stable bearing arrangement when pressed into a suitable housing.
- Improved Performance: Low cross-sectional height allows for larger shaft diameters, increasing the overall strength of the assembly.
- Reduced Costs: An economical bearing solution that lowers both initial component cost and assembly time.
- Versatile Functionality: Suitable for a broad range of industrial, automotive, and consumer product applications.
