Provides reliable protection against dust, dirt, and moisture, making it ideal for challenging operating environments.
Precisely machined raceways guide high-precision steel balls for smooth, even rotation and optimal load distribution.
High-grade bearing steel components with sheet metal cage for strength, durability, and thermal conductivity.
- High Radial Load Capacity: Evenly distributes radial forces for heavy-duty applications
- Axial Load Accommodation: Handles combined radial and axial loads in both directions
- Low Friction Operation: Enables high-speed capability up to 11,000 rpm with oil lubrication
- Quiet Operation: Optimized for low-vibration, low-noise performance in sensitive applications
- Industrial Machinery: Conveyor systems, machine tools, and manufacturing equipment
- Electric Motors: Medium to high-power motor applications requiring reliable rotation
- Automotive Industry: Engine components, water pumps, and transmission systems
- Household Appliances: Washing machines, fans, and other quiet-operation equipment
Installation: Use proper tools (hydraulic press, bearing installation sleeve) for even installation. Ensure correct alignment with shaft and housing to prevent premature wear.
Maintenance: Regular lubrication with lithium-based grease (fill 1/3 to 1/2 of bearing space). Monitor temperature (normal range: 60-80°C) and watch for abnormal vibration or noise indicating potential issues.
