Screw Jack Parts And Materials

A worm gear machine screw jack is the most common type of mechanical actuator, valued for its high load capacity and inherent self-locking safety. It uses a worm gear mechanism to convert high-speed, low-torque input into powerful, controlled linear movement. Worm Shaft (Input), Alloy Steel (20CrMnTi), Receives input torque; case-hardened for high wear resistance and strength. Worm Gear (Drive Sleeve), High-Tensile Bronze, Mates with the worm shaft; chosen for anti-galling and low-friction properties.

Parts And Materials

A worm gear screw jack primarily consists of a worm screw, worm gear, lifting screw (or spindle), and a housing. The worm screw rotates and engages with the worm gear, which then drives the lifting screw to raise or lower a load. These components work together to convert rotary motion into linear motion for lifting or positioning loads. High-quality materials, typically produce the best-performing worm gear screw jacks. Below is a summary of the various materials used in machine screw jack construction.
