Bevel Ball Actuators

EP Bevel Ball Actuators (BB), available in 7.5-ton to 100-ton static capacities, are designed for near-continuous duty operation. These are EP’s fastest jacks, able to attain travel speeds of 48.6 feet per minute. Available in Translating and KFTN designs, bevel ball actuators act as miter boxes, making them an ideal choice for multi-jack systems. As many as three output shafts may be specified for mounting motors, limit switches, readout devices and other accessories.

  • Higher speeds and less heat generation than other mechanical actuators
  • Require a brake or other external locking device to hold position
  • More precise positioning and repeatability than hydraulic cylinders
  • Fully predictable J-10 ball nut life expectancy
  • Right hand screws standard (left hand screw available)
  • Threaded end conditions standard (load pad, clevis, and plain end condition available)
  • Protective boots and other options are available
  • Custom finishes available

EP Bevel Ball Actuators (BB) come in four capacities:

Important Note: Bevel Ball Actuators are not self-locking. Brake motors or external locking systems are required.
*W: Load in Pounds.
Pinion Torque (raising): The torque required to continuously raise a given load.
Pinion Torque (holding): The torque required to hold a given static load in position.
Screw Torque: The torque required to resist screw rotation (translating design) and traveling nut rotation (KFTN design).
Lead: The distance traveled axially in one rotation of the lifting screw.
Pitch: The distance from a point on the screw thread to a corresponding point on the next thread, measured axially.
