40x80x18 Deep Groove Ball Bearing High Speed 6208E Bearing For Industrial / Household
6208E is a deep groove ball bearing designed for industrial and household appliances. These bearings are representative rolling bearings with wide applications, suitable for high rotational speeds and extremely demanding conditions. They offer excellent durability and require minimal maintenance.
This bearing type features low friction coefficient, high limiting speed, simple structure, low manufacturing cost, and high precision manufacturing capabilities. Available in various sizes and configurations, they are used across precision instruments, low-noise motors, automobiles, motorcycles, and general machinery industries.
| Parameter | Value | Description |
|---|---|---|
| Bore Diameter (d) | 40 mm | Matches the shaft diameter |
| Outer Diameter (D) | 80 mm | Dimension for installation space |
| Width (B) | 18 mm | Thickness of the bearing |
| Weight | Approx. 0.37-0.38 kg | Varies slightly based on sealing structure |
| Dynamic Load Rating (Cr) | Approx. 31.3 kN | Capacity to withstand radial dynamic loads |
| Static Load Rating (Cor) | Approx. 18.6 kN | Load-bearing capacity under static or low-speed conditions |
- Primarily bears radial loads while accommodating axial loads (axial load-bearing capacity improves with increased radial clearance)
- Excellent high-speed performance with limiting speed of 6,600 r/min for grease lubrication
- Meets high-speed operation requirements for motors, reducers, and other equipment
Allows slight tilt (≤ 8′-16′, depending on clearance) between inner and outer rings, compensating for installation errors and enhancing stability in complex working conditions.
Constructed from high-carbon chromium bearing steel (GCr15, fully quenched) with precision heat treatment and machining. This ensures excellent wear resistance and fatigue resistance, guaranteeing long service life.
Thanks to its high speed, low noise, and adaptability to multiple scenarios, the 6208E is utilized across numerous industries:
- General Machinery: Core transmission components including motors, reducers, belt conveyors, idlers, and hoists
- Transportation Equipment: Transmission systems of automobiles and motorcycles
- Industrial and Household Sectors: Medical devices, agricultural machinery, office equipment, household appliances, and power tools
