Description
Basic Parameters
The Deep Groove Ball Bearing 6406 is a heavy-series bearing characterized by its “6” prefix indicating it is a deep groove ball type, designed for high radial load capacity with some ability to withstand axial loads. The “4” in the model denotes the heavy diameter series, meaning it has larger outer diameter (72mm) and width (19mm) compared to lighter series, making it suitable for heavy-duty applications. The inner diameter, derived from the “06” code (calculated as 06 × 5), is 30mm. With a default tolerance grade of Grade 0 (normal precision), it offers standard dimensional and rotational accuracy for general machinery. Its typical applications include industrial motors, reducers, mining equipment, and conveyors, where it supports high radial loads in moderate-to-high-speed operations. For higher precision needs, grades like P6 or P5 can be specified additionally.
Product Application
1. Industrial Power Transmission Equipment
Electric Motors & Gear Reducers: Serves as a support component for motor spindles or gear shafts in reducers, handling high radial loads and start-stop impacts. It adapts to the high-speed operation requirements of medium-to-small industrial motors (e.g., 15-30kW motors) and gear reducers, ensuring tranmission efficiency and long-term reliability.
Compressors & Pumps: Supports impeller shafts in centrifugal water pumps and air compressors, withstanding radial pressures and axial pulsating loads from fluid media. Suitable for conventional conditions in water pumps, oil pumps, etc., and can be equipped with seals (e.g., 6406-2RS) for dusty or wet environments.
2. Heavy Machinery & Mining Equipment
Mining Conveyors & Screening Machinery: Used to support roller shafts in belt conveyors and main shafts in vibrating screens, enduring heavy-duty impacts and vibrations during ore transportation. The heavy-series structure design minimizes bearing deformation risks and extends maintenance intervals in harsh mining conditions.
Crushing & Grinding Equipment: Installed in the main shafts of jaw crushers or ball mills, resisting high-frequency impact loads from material crushing and grinding processes, ensuring stable operation in high-load, low-speed applications.
3. Agricultural Machinery
Tractor Transmissions & Harvester Drives: Supports gear shafts in tractor gearboxes and cutting mechanism drives in combine harvesters, handling variable radial loads from agricultural operations (e.g., tilling, harvesting). Its simple structure allows for easy maintenance, critical for minimizing downtime in field machinery.
Irrigation Pumps & Grain Processing Equipment: Used in water pump shafts for irrigation systems and conveyor rollers in grain dryers, tolerating moisture, dust, and occasional misalignment common in agricultural environments.
4. Transportation & Conveyor Systems
Conveyor Rollers & Logistic Equipment: Installed in roller shafts of warehouse conveyors or baggage handling systems, enabling smooth material transportation under medium-to-heavy loads. Its high-speed compatibility ensures efficient operation in automated logistics lines.
Light Industrial Vehicles: Used in wheel hubs or drive shafts of electric forklifts and AGVs (Automated Guided Vehicles), balancing radial loads from vehicle weight and axial forces from steering, supporting precise motion control in narrow-space operations.
5. General Industrial Machinery
Printing & Packaging Machines: Supports rotating cylinders in offset presses or sealing rollers in packaging lines, maintaining high rotational accuracy for consistent production quality, even under frequent start-stop cycles.
Ventilation Systems & Fans: Used in fan shafts of industrial blowers or air conditioning units, optimizing energy efficiency through low-friction operation and resisting axial loads from impeller imbalances.
