Understanding the 3 Types of Machine Screw Jack Designs
Jacks come in three basic designs – Translating, Keyed for Non-Rotation, and Keyed for Traveling Nut (KFTN). They can be specified with a choice of four standard screw end conditions, T1-plain turned end, T2-load pad end, T3-threaded end, or T4-Male clevis end. Translating screw jacks are the most commonly specified jacks.
