Heavy Duty Electric Cylinders

Electric Cylinder Types

ELECTRIC CYLINDER - DD (500 to 40,000 lbs.)

An alloy steel worm drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial ball bearings available). Single reduction.

  • Drive sleeve is supported on anti-friction tapered roller or ball thrust bearings.
  • Ductile iron housing proportioned to support the rated capacity.
  • Part Number Reference

ELECTRIC CYLINDER - ILA (1,000 to 21,000 lbs.)

Designed to have a motor or gear reducer directly coupled to the lift shaft for faster, more precise operation and higher duty cycles. Inline.

  • Standard trunnion pin mounting.
  • Easily adapted for use with servo motors and planetary gear reducers.
  • Available with keyed actuator tubes.
  • Part Number Reference

ELECTRIC CYLINDER - RAD (3,500 to 40,000 lbs.)

Same as DD with a second stage gear reduction to provide higher thrust at lower speeds. Single and double reduction.

  • Reducer and motor can be mounted in eight possible positions for maximum flexibility.
  • Variety of worm gear ratios resulting in a wide range of speeds and thrust capacities.
