Description

Basic Parameters

The 6307 Deep Groove Ball Bearings feature a bore diameter of 35mm, an outer diameter of 80mm, and a width of 21mm, designed to accommodate both radial and axial loads efficiently. Constructed with high-quality steel for durability and low friction, these bearings offer a dynamic load rating of 33.2kN and a static load rating of 20.2kN, ensuring reliable performance under various operating conditions. With a maximum operating speed of up to 9,000 RPM (grease-lubricated) or 11,000 RPM (oil-lubricated), they are suitable for applications in industrial machinery, automotive systems, home appliances, and power transmission equipment, where precision, stability, and long service life are essential.

 

 

Product Application

1. Industrial Machinery & Equipment
Ideal for motors, pumps, and gearboxes, where they efficiently handle combined radial and axial loads in high-speed operations (up to 11,000 RPM with oil lubrication). In conveyor systems and production lines, their low-friction design reduces energy consumption while ensuring smooth material transport. They also excel in compressors and machine tools, providing stability for precision machining processes and minimizing vibration to extend equipment lifespan.
2. Automotive Systems
In automotive applications, these bearings are critical for engine auxiliary components (e.g., alternators, water pumps), where they withstand high temperatures and dynamic loads. They also support transmission systems and wheel hubs in light vehicles, delivering consistent performance for reliable power transmission and rotational accuracy. Additionally, they are used in steering systems and air conditioning compressors, ensuring durability in harsh operating environments with frequent start-stop cycles.
3. Home Appliances & Consumer Electronics
For household appliances like washing machines, dryers, and refrigeration compressors, the 6307 bearings offer quiet operation and long service life, even under intermittent loads. Their compact size (35mm bore, 80mm OD, 21mm width) makes them suitable for power tools (e.g., drills, saws) and small motors in fans or blowers, where space efficiency and low noise are essential. The bearings’ corrosion-resistant surfaces (when treated with optional coatings) also make them suitable for humid environments in kitchen or bathroom appliances.
4. Renewable Energy & Power Generation
In wind turbines and solar tracking systems, the 6307 bearings enable smooth rotational movement under varying loads, contributing to energy efficiency. They support hydroelectric pumps and generator drives, resisting moisture and delivering high reliability in demanding outdoor conditions. Their ability to handle both radial loads (up to 33.2kN dynamic rating) and moderate axial forces makes them a cost-effective choice for renewable energy applications requiring long maintenance intervals.
5. Agricultural & Heavy Machinery
Used in tractor transmissions, harvester drives, and irrigation pumps, these bearings endure dusty, dirty, and high-impact environments. Their heat-treated steel construction (ISO-compliant material standards) enhances resistance to abrasion and fatigue, critical for maintaining uptime in agricultural equipment that operates long hours under heavy loads. They also support construction machinery such as compactors and mixers, where vibration and shock loads are common.
6. Aerospace & Aviation (Subsystems)
While primarily used in non-critical aerospace subsystems, the 6307 bearings provide reliable performance in ground support equipment (e.g., baggage conveyors, aircraft lifts) and avionics cooling systems, meeting strict weight and performance requirements. Their precision tolerances ensure consistent rotational stability in low-clearance installations, essential for maintaining safety and efficiency in aviation-related applications.
