    Worm Gear Jacks  
Applied offers two types of worm gear jacks - machine screw jacks and ball screw jacks. The worm gear driven machine screw jack incorporates an alloy steel worm which drives a high strength bronze worm gear or drive sleeve. The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication. The drive sleeve is supported by anti-friction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration. Ball screw jacks use the same worm gear set arrangement as machine screw jacks. The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the machine screw jack.
