The 6805 2RS Ceramic Bearing is a high-performance, thin-section deep groove ball bearing designed for high-speed applications, particularly in bikes and other precision machinery. This bearing features ceramic rolling elements, which provide exceptional strength, low friction, and resistance to wear and corrosion. With C3 clearance, it offers optimal internal clearance for reduced friction and efficient performance, even under high-speed or high-temperature conditions. The double rubber seals (2RS) provide excellent protection against dust, debris, and moisture, making it ideal for outdoor and demanding environments. Its thin-section design ensures a compact and lightweight solution for applications where space and weight are critical.
Ceramic Rolling Elements: Provides exceptional strength, low friction, and resistance to wear and corrosion.
Double Rubber Seals (2RS): Protects against contamination and retains lubricant for extended performance.
C3 Clearance: Optimized internal clearance for reduced friction and efficient performance.
High-Speed Capability: Designed for smooth operation at high rotational speeds.
Thin-Section Design: Compact and lightweight, ideal for applications with space constraints.
Durable Construction: Combines ceramic rolling elements with high-quality steel races for excellent wear resistance.
Low Maintenance: Sealed design reduces the need for frequent relubrication.
Versatility: Suitable for both radial and axial load applications.
| Parameter | Measurement (mm) |
|---|---|
| Inner Diameter (ID) | 25 mm |
| Outer Diameter (OD) | 37 mm |
| Width (W) | 7 mm |
High-Speed Performance: Ceramic materials reduce friction, enabling smooth operation at high rotational speeds.
Low Friction: Ceramic rolling elements minimize energy loss and heat generation.
Corrosion Resistance: Ceramics are resistant to rust and corrosion, making them ideal for outdoor and wet environments.
Dustproof and Waterproof: The double rubber seals (2RS) ensure reliable performance in harsh conditions.
Lightweight: Ceramic balls are lighter than steel, reducing the overall weight of the bearing and improving efficiency.
Durability: High-quality materials and construction provide excellent resistance to wear and tear.
Bikes: Used in bike hubs, bottom brackets, and other components requiring high-speed and low-friction performance.
Electric Motors: Suitable for high-speed motors in appliances, tools, and industrial equipment.
Robotics: Provides reliable performance in robotic joints and small mechanical parts.
Industrial Machinery: Ideal for pumps, compressors, and gearboxes requiring high precision and durability.
Medical Equipment: Ensures precise and smooth operation in devices like centrifuges and small medical tools.
Hobby and DIY Projects: Perfect for small-scale mechanical projects and model building.
