Description
Basic Parameters
The 6207 Deep Groove Ball Bearing is a widely used mechanical component with standardized dimensions and performance characteristics. It features a bore diameter of 35 mm, an outer diameter of 72 mm, and a width of 17 mm 123. Designed to handle both radial and axial loads, this bearing has a basic dynamic load rating of 25.7 kN (25,700 N) and a basic static load rating of 15.3 kN (15,300 N).
For rotational performance, the bearing achieves a maximum speed of approximately 9,500–9,800 revolutions per minute (rpm) under grease lubrication and 11,000 rpm with oil lubrication 346. These values align with industry standards but may vary based on specific operating conditions and lubricant types. Weighing around 0.28 kg (0.27–0.29 kg across manufacturers), it offers a balance between durability and lightweight design 3813. Constructed from high-grade bearing steel with a sheet metal cage, the 6207 ensures reliable operation in applications ranging from industrial machinery to automotive systems 210. Its open design allows for easy maintenance, while optional seals or shields can be integrated for dusty or corrosive environments 14. Overall, this bearing exemplifies versatility, combining high load capacity with smooth, low-friction rotation suitable for diverse mechanical setups.



Product Application
In automotive applications, the 6207 bearing excels in both powertrain and auxiliary systems. Within wheel hubs, it supports the rotational mass of the wheel while enduring complex loads from road irregularities, combining radial stability with moderate axial resistance for safe handling. In manual and automatic transmissions, it facilitates the smooth operation of gear shafts, minimizing backlash and enhancing shift precision. Engine accessories such as water pumps, alternators, and air conditioning compressors rely on its compact size (35 mm bore, 72 mm OD) and heat-resistant bearing steel construction to withstand high-temperature environments and repetitive start-stop cycles. Additionally, in power steering systems, the bearing’s low friction and high-speed capability contribute to responsive steering feel, ensuring optimal control across all driving conditions.
The bearing’s versatile dimensions make it a preferred choice for consumer electronics and home appliances requiring balanced performance and cost efficiency. In washing machines and dryers, it supports the drum shaft, handling radial loads from unevenly distributed laundry and axial forces from rotational imbalances, while its open design allows for easy lubrication maintenance to extend service life. Air conditioning units and ceiling fans utilize its quiet operation and smooth rotation to minimize noise pollution, with sealed variants (when equipped with optional shields) protecting against dust and moisture in humid environments. Even in smaller devices like power tools (e.g., drills, saws), the 6207 bearing provides the durability needed for high-torque applications, ensuring consistent performance during heavy-duty use.
For heavy-duty environments in construction and agriculture, the 6207 bearing is engineered to withstand harsh conditions. In excavators, loaders, and bulldozers, it is used in swing mechanisms, boom joints, and track drives, where it must handle shock loads, dirt, and vibration. Manufacturers often recommend sealed versions with rubber or metal shields to prevent contamination by dust, mud, or moisture, preserving lubrication integrity in off-road operations. Agricultural equipment such as tractors, combines, and irrigation pumps benefit from its robust design—heat-treated steel rings enhance wear resistance against the abrasive particles common in farming environments. The bearing’s ability to operate at moderate speeds with high reliability reduces downtime in critical machinery, ensuring productivity during planting, harvesting, and material handling.
In precision-oriented applications, the 6207 bearing’s dimensional accuracy (ISO tolerance class IT08 for diameters) and low runout are essential. CNC machine tools rely on it for spindle support, maintaining positional precision during high-speed machining to achieve tight tolerances in component fabrication. Printing presses and textile machinery utilize its smooth rotation to prevent vibrations that could distort output quality, while packaging equipment benefits from its consistent performance in high-cycle count operations. Even in medical devices like diagnostic imaging systems (e.g., X-ray tables), the bearing’s lightweight design (≈0.28 kg) and low magnetic permeability (in special variants) make it suitable for sensitive, precision-guided movements.
The 6207 bearing plays a vital role in renewable energy systems, adapting to the unique demands of wind and solar applications. In small-scale wind turbines, it supports generator shafts, efficiently converting rotational energy into electricity while enduring cyclic loads from turbulent wind conditions. Solar tracking systems use it to facilitate the smooth movement of panel arrays, with optional corrosion-resistant coatings (e.g., zinc plating) protecting against outdoor elements like UV radiation and moisture. Its compatibility with both grease and oil lubrication allows for flexible maintenance schedules in remote or hard-to-reach installations, ensuring long-term reliability in clean energy infrastructure.
Manufacturers offer variants of the 6207 bearing to address niche requirements, such as stainless steel constructions for food processing (meeting hygiene standards) or ceramic hybrid designs (with silicon nitride balls) for high-temperature or electrically insulated applications. Whether integrated into aerospace ground support equipment, marine pumps, or industrial robotics, the bearing’s standardized dimensions and modular design enable easy replacement across global supply chains, making it a universal solution for engineers and maintenance teams seeking performance, durability, and cost-effectiveness.
