6305 2RS
A Deep Groove Ball Bearing is one of the most widely used types of rolling bearings. It consists of an inner ring, outer ring, steel balls, and a cage (or sealing components). The deep groove raceways on the inner and outer rings allow it to withstand radial loads and limited bidirectional axial loads simultaneously. Known for its simple structure and reliable performance, it is extensively used in various mechanical equipment.

Features of Deep Groove Ball Bearings
- High-Speed Capability: Optimized raceway design minimizes friction, enabling high-speed operation.
- Low Friction Loss: Small contact area between balls and raceways reduces resistance and energy consumption.
- Long Service Life & Reliability: High-quality steel and precision machining ensure durability and stability.
- Bidirectional Load Capacity: Accommodates radial loads and bidirectional axial loads.
- Easy Installation: No alignment adjustment required, simple structure, and low maintenance costs.
Classification of Deep Groove Ball Bearings
- By Sealing Type:
- Open Bearings: No seals; require regular lubrication.
- Shielded Bearings (ZZ/2Z): Single or double metal shields for dust protection (not oil-tight).
- Sealed Bearings (RS/2RS): Rubber seals for dust/water resistance and grease retention.
- By Size:
- Miniature Bearings: Bore diameter <10mm, used in precision instruments.
- Standard Bearings: Common sizes (e.g., 6200 series).
- Large-Size Bearings: For heavy-duty industrial equipment.
- Special Types:
- Stainless Steel Bearings: Corrosion-resistant for humid/chemical environments.
- Ceramic Hybrid Bearings: Ceramic balls for high-temperature and anti-magnetic applications.
Applications of Deep Groove Ball Bearings
Deep groove ball bearings are used across almost all industrial sectors, including:
- Motors & Generators: Supporting high-speed rotor rotation.
- Automotive Components: Gearboxes, wheel hubs, belt tensioners.
- Household Appliances: Motors in washing machines, air conditioners, and vacuum cleaners.
- Industrial Machinery: Pumps, fans, conveyor belts, machine tool spindles.
- Precision Equipment: Medical instruments, robotic joints, drone motors.
Warm reminder: We offer a wide range of deep groove ball bearings in various specifications and models. Please select the most suitable product based on your specific application requirements (such as load magnitude and direction, speed, accuracy requirements, installation space, environmental conditions, etc.).
