At , we specialize in manufacturing high precision rack gears engineered for accurate linear motion, smooth meshing, and long service life. Our rack gears are produced using advanced CNC gear cutting and precision machining processes to meet demanding industrial standards.

Rack gears are essential components in rack and pinion systems, converting rotational motion into linear motion with high efficiency. Our precision ensures minimal backlash, smooth travel, and reliable performance under heavy loads.

⚙️ What Is a Rack Gear?

A rack gear is a straight gear bar with teeth that meshes with a pinion gear to convert rotational motion into linear movement. It is widely used in CNC machines, automation systems, material handling equipment, and heavy machinery where precise positioning is required.

Due to continuous engagement with the pinion, tooth accuracy, hardness, and alignment are critical for performance and durability.
