EGHS120F Motorized Ball Screw Slide

From carriage movement to a repeatable tool position

A positioning axis must move the attached tool as well as its own carriage. A camera bracket, dispensing fixture or assembly plate becomes part of that moving structure, so the connection between the tool and the slide matters alongside the drive specification.

The EGHS120F Ball Screw Linear Slide provides four M6 threaded holes and two Ø5 H7 locating holes at the moving interface shown in the catalog drawing. These features serve different purposes: the screws clamp the attached plate, while matching locating pins establish its position. This gives a removable fixture a defined mounting reference instead of relying entirely on the clearance around its fastening screws.

The connection can also be kept close to the carriage. A short adapter places the tool nearer the guide assembly, reducing the leverage created by an offset load. This is particularly useful when a camera or process head must face sideways rather than sit directly above the slide.

Beneath the mounting interface, four EGH15 blocks run on two EGR15 rails. The rails flank a central Ø16 mm C7 ball screw, as shown in the internal product photograph. The carriage bridges the guides, while the screw supplies movement along the axis. This arrangement supports the attached fixture at separated positions rather than asking the screw to act as its guide.

Define the move, then select the drive

For a repeated inspection or assembly sequence, the relevant motion includes travel between positions, slowing before arrival and remaining stationary while the process takes place. The published ±0.02 mm repeatability provides a reference for returning to a position. Tooling stiffness and settling behavior still influence the result at the actual working point.

Four screw leads give the EGHS120F Ball Screw Linear Slide different operating ranges:

The handling weight includes everything carried by the moving platform: adapter plate, bracket, tool and workpiece. Selecting from that complete assembly prevents a small workpiece from disguising a much heavier fixture. Each column of performance must also remain associated with its corresponding lead.

The aluminum base brings the screw supports and guide mounting into one module. Its 120 mm body width and the illustrated 140 mm carriage width give the machine builder distinct dimensions for the fixed structure and moving clearance. BC, BL, BR and BM motor arrangements provide alternative ways to connect the drive around neighboring equipment.

Together, the locating features, four-block guidance and selectable screw leads provide concrete interfaces for integrating the slide into a repeated positioning task. The complete drawings remain the reference for hole locations and the selected motor arrangement.

About Us

Guangyuan manufactures ball screws, linear guides and assembled linear-motion modules. Our EGHS120F documentation includes separate installation drawings for BC, BL/BR and BM arrangements, with mounting dimensions listed by stroke.

The series supports 57/86-frame stepper motors and 100 W, 200 W or 400 W servo motors. We accept drawing-based OEM/ODM enquiries for mounting and connection requirements. A fixture drawing, motor interface and operating sequence help define the requested assembly and supply scope.

The minimum order quantity is 1 unit. The quotation should specify whether the motor, driver, controller, switches and sensors are included.
