Electromagnetic Rings generate a repulsive force between seal and rod
Suspension Gap: Maintains 50-200 μm non-contact clearance at rest
Active Gap Control: Sensors adjust magnetic force in real-time for consistent gap
Viscous Fluid Layer: Magnetorheological fluid creates dynamic seal in the gap
Friction: Near-zero (μ < 0.01)
Speed: Up to 8 m/s
Leakage: < 0.1 ml/hr (magnetorheological fluid dependent)
Power: 24V DC, < 10W
Life: 50,000+ hours (no mechanical wear)
High-speed servo cylinders
Ultra-clean hydraulic systems
Vacuum/pressure hybrid chambers
Precision metrology equipment
Self-Diagnosis: Monitors gap stability and fluid integrity
Adaptive Mode: Switches to contact mode if power fails
Data Logging: Tracks performance and predicts maintenance
Patented EM technology eliminates wear by replacing friction with controlled magnetic repulsion—ideal where precision and longevity outweigh complexity.
