Friction Springs
Key Characteristics of the Friction Springs
RINGFEDER® Friction Springs are composed of meticulously crafted outer and inner rings, assembled into complete spring columns tailored to the user's specific requirements. Each spring undergoes rigorous testing and multiple load cycles before delivery, ensuring absolute functional reliability. It also known as "lò xo ma sát".
RINGFEDER® Friction Springs offer several advantages over conventional damping solutions:
- High spring work at low weight and volume: Optimal use of spring material reduces dimensions and weight.
- High damping capability: Standard damping at 66% quickly absorbs energy and suppresses resonance. Damping variations (33%-66%) are possible with specific lubricants.
- Performance independent of load speed: Full spring work and damping effect regardless of load speed.
- Overload-safe: Designed to "block," preventing damage and exceeding admissible stresses.
- Temperature-independence: Consistent characteristic curve from -20°C to +60°C, unaffected by temperature fluctuations.
- Maintenance-free: Generally does not require relubrication; using other lubricants may cause failure.
- Flexible arrangement: Parallel for higher forces, serial for more spring travel.
- Custom designs: Tailored solutions for specific applications beyond standard offerings.
