Performance Advantages
- 15% higher axial rigidity vs. standard deep groove bearings[2]
- Sealed design prevents lubricant leakage in food-grade environments
- ISO 9001-certified manufacturing with ≤5μm dimensional tolerance
2. Key Applications & Industrial Usage
Primary Industries Served
- Food Processing. Hygienic bearing solutions for mixers, conveyors, and packaging lines
- Pump Systems. High-speed booster pumps (up to 18,000 RPM)
- Robotics. Precision motion control in automated production cells
Operational Requirements
- Temperature range: -30°C to +120°C (extendable with special grease)
- Minimum axial preload: 0.03C (C=basic dynamic load rating)[4]
- Lubrication interval: 5,000 operating hours (standard grease)
3. Operational Best Practices
Installation Guidelines
- Clean mounting surfaces with ISO 4406 14/11/8 cleanliness standard
- Use induction heaters (max 120°C) for interference fits
- Verify runout ≤0.005mm after installation
Maintenance Protocol
- Monthly vibration analysis (recommended ISO 10816 thresholds)
- Annual grease replacement with NSF H1-certified lubricants
- Torque monitoring for mounting bolts (20-25 Nm range)
4. Real-World Use Cases
