Vogthan® (95 Shore A)
Vogthan® (95 Shore A)
Vogthan®: Low heat build-up, high-rebound polyurethane. Low heat generation and energy loss in continuous rolling, carries load at high speed, good fatigue resistance, handles higher speeds for short periods.
Typical Operating Conditions
- Typical equipment: roller coaster running, guide and upstop wheels, guide wheels for special offshore equipment, high-speed rollers and drive wheels.
- Load and speed: carries load at high speed; high dynamic loads with fast load cycles.
- Duty: long continuous running without overheating; quiet, smooth ride.
