JTD Cubic Ball Screw Jacks

JTD Cubic Ball Screw Jacks featuring a compact and versatile cubic housing. Cubic Ball Screw Jacks are an excellent solution for industrial lifting, lowering, pushing and/or pulling applications that require higher efficiency, greater accuracy or faster travel speeds than offered by Worm Gear Machine Screw Jacks. The addition of a high efficiency ball screw and nut reduces the required input torque. Required approximately two-thirds less input torque to move the load than similarly rated machine screw jacks. They are NOT self-locking so a brake motor or external locking device needs to be included in the drive system and hand wheels are not a recommended option. Can be mounted in any attitude. Generally maintenance free.
