LD SERIES

LD SERIES - Description


MASCOT LDSeries hydraulic motors are designed for high power and high speed applications. The compact size, light weight and ease of installation make these motors highly suited also for mobile applications. Several mounting options are available for high radial load applications. The axial load capacity of LD series motors is high. This makes them very suitable for use in Paddle Feeder Wheel Drive and other applications where axial forces are more. Parking brake at the front side of the motor ensures high holding torque.


OPTIONS

  • Customised shaft.
  • Integral multi plate disc brake (Static / Parking).
  • High speed versions.
  • Double shaft.
  • Super low noise.
  • Corrosion resistant material.
  • Through hole shaft of various sizes.
  • Custom finish.
  • Deep water submersible.
  • Non magnetic material.
  • Dual Displacement.

FEATURES

  • Long Life
  • High Mechanical Efficiency
  • Constant torque output
  • Smooth low speed performance < 1rpm
  • Resistance to thermal shock
  • Double shaft sealing
  • Shrink disc coupling
  • Shaft or Flange mounting
  • Shock Resistance
  • Low noise
