- Load Range: 0.5-15 kN for small to medium load applications
- Superior shock absorption with damping coefficient of 0.25-0.35
- Stiffness range: 8-45 N/mm depending on thickness (0.5-5mm) and outer diameter (10-150mm)
- Conical geometry enables precise load-deflection control
- Ideal for compact mechanical assemblies
- Phosphating (per ISO 10276): Creates corrosion-resistant phosphate film (5-15μm thickness) suitable for dry indoor conditions
- Blackening (per MIL-DTL-13924): Forms uniform oxide layer that improves wear resistance and aesthetic finish
- Optional Oil-Impregnated Treatments: Reduces friction coefficients by 30% compared to untreated surfaces
Available in both standard DIN 2092 sizes and custom configurations with tolerances as tight as ±0.02mm for critical dimensions. Rigorous quality testing includes load-deflection curve validation (±3% tolerance) and hardness testing (42-48 HRC).
Ideal applications include CNC machine tool spindles, coordinate measuring machines (CMMs), optical inspection equipment, servo motor brakes, precision press tools, and semiconductor manufacturing equipment.
