Bevel Gear Ball Screw Jacks, also called Bevel Ball Actuators, they are available in 1-ton to 20-ton static capacities, are designed for near-continuous duty operation. These are the fastest jacks, able to attain travel speeds of 10 meters per minute. Available in Translating and Travelling Nut designs, bevel ball actuators act as bevel gear boxes, making them an ideal choice for multi-jack systems. Other details, for example: 1. Higher speeds and less heat generation than other mechanical actuators. 2. Require a brake or other external locking device to hold position. 3. More precise positioning and repeatability than hydraulic cylinders. 4. Right hand screws standard (left hand screw available). 5. Threaded end conditions standard (top plate, clevis, threads and plain end condition available). 6.Protective boots and other options are available.
