Linear Motion Components for CNC Machines
Ball screws, linear guideways and related motion components for CNC machine X, Y and Z axes.
CNC machines require stable guidance and accurate linear drive for table movement, gantry travel, spindle positioning and feed motion. DLY supplies linear motion components for new CNC equipment, machine building and replacement projects.
Where Are Linear Motion Components Used in CNC Machines?
The main CNC motion system can be understood very simply: linear guideways guide and support the moving structure, while ball screws drive the axis forward and backward.
X-Axis Travel
The X-axis usually provides horizontal travel for the machine table, gantry or cutting head.
Common products:
Ball Screw + Linear Guideway
Y-Axis Travel
The Y-axis controls movement in the second horizontal direction and must support the moving load while maintaining stable positioning.
Common products:
Ball Screw + Linear Guideway
Z-Axis / Spindle Movement
The Z-axis commonly moves the spindle or cutting head vertically and therefore requires stable guidance and sufficient rigidity.
Common products:
Ball Screw + Linear Guideway + Support Unit
Main DLY Products for CNC Machines
Ball Screws - CNC Axis Drive
Ball screws convert motor rotation into linear movement and are commonly used to drive CNC machine X, Y and Z axes.
Diameter, lead, accuracy grade and screw length should be selected according to travel, speed, load and positioning requirements.

Linear guideways support the moving table, gantry or spindle assembly and keep the axis moving along a controlled linear path.
CNC machines may use heavy-duty ball guideways or roller guideways depending on load, cutting force, rigidity and accuracy requirements.

Ball Screw Support Units - Screw Installation
Support units are installed at the ends of the ball screw to support rotation and maintain the required axial position.
Common CNC combinations include BK/BF, FK/FF and EK/EF, selected according to screw diameter, end machining and machine structure.
Linear Modules - Complete Linear Axis
For auxiliary positioning, loading, inspection or automated handling around CNC equipment, a complete linear module can simplify machine integration.
Linear modules combine drive and guidance components into a compact motion unit.
