Knowledge Base

Screw Jack Working Principle

Screw Jack Working Principle

Screw Jacks are found wherever there is a need to lift, position and hold load. A Screw Jack (also known as a Jack Screw, a Worm Screw Jack, a Machine Screw Jack or a Lead Screw Jack) is a devise used to convert rotational motion into linear motion.

Worm and Wheel

Worm and Wheel

Worm Drives are used when the axis of rotation of a shaft must change direction. Being low-cost, potentially self-locking and providing high gear reductions, Worm Drives provide an effective means of decreasing speed whilst increasing torque.

Bevel Gear Sets

Bevel Gear Sets

Bevel gears are used when the axis of rotation of a shaft must change direction. Providing a highly efficient and durable means of gear reduction, Bevel Gear sets have many uses.

Specialising in screw jacks and custom-purpose linear actuators, Kelston Actuation's legacy of precision manufacturing stretches back more than 40 years
