Guide rail slider

A linear guide block is a mechanical component designed to provide linear reciprocating motion, widely used in various types of machinery, such as automation equipment, precision machine tools, and production lines. Its primary function is to support and guide moving parts, ensuring high‑precision linear motion even under heavy loads. By utilizing rolling steel balls to support the moving components, this design delivers outstanding performance in terms of high-speed operation, low friction, and high sensitivity.

Lead screw nut

A ball screw is a mechanical transmission device that converts rotary motion into linear motion, primarily consisting of a screw, a nut, and steel balls. Its operating principle relies on the helical grooves on the screw and the recirculating grooves within the nut; steel balls roll along these grooves, transmitting force and torque and thereby converting rotary motion into linear motion.

Rack and pinion

Rack and pinion is a common mechanical transmission method that transmits power through the meshing engagement of a gear and a rack. Its operating principle is based on the meshing of gears: when the gear and rack are engaged, each tooth of the gear meshes with the corresponding tooth space of the rack, thereby transmitting motion. By adjusting the rotational speed or direction of the gear, the linear velocity and direction of the rack can be controlled.
