Wet Running Multi-Disc Clutches KMS


Oil cooled and hydraulically operated Multi-Disc Clutches for ship, for marine gears. They are used where high torques must be transmitted reliably in the smallest spaces. Setting the trend for Stromag development work is the "No Limit" (KMS 200,000). With a rated torque of over 2,000,000 Nm, a diameter of 1.2 m, and a weight of nearly 4 t, it is the largest and most powerful clutch to date on the entire drive sector.

    • All torques realisable
    • Excellent torque to weight ratio
    • Low mass moment of inertia
    • High thermal load capacity
    • Switching heat dissipated by internal oil cooling
    • Long service life of the discs
    • Low maintenance, any disc wear automatically compensated by piston travel
    • Remote control capability
    • Continuous increase of oil pressure, and so shockless switching
    • Mechanical emergency operation device on failure of hydraulic oil supply
