Product Specifications

Technical details and manufacturing context for Linear Actuator/Guide

Definition
The Linear Actuator/Guide is a critical sub-assembly within a Lamination Feeder, responsible for accurately positioning and moving lamination materials (such as films, foils, or papers) along a predetermined linear path. It ensures smooth, repeatable motion with minimal friction and precise alignment during the feeding process.
Working Principle
Typically consists of a linear actuator (e.g., ball screw, lead screw, or pneumatic/hydraulic cylinder) that converts rotational or fluid power into precise linear displacement, coupled with a linear guide system (e.g., rail and carriage with recirculating ball bearings) that constrains the motion to a single axis, providing high rigidity and load capacity while minimizing deflection and wear.
Common Materials
Hardened steel, Aluminum alloy, Engineering plastics (for bearings/sliders)
Technical Parameters
  • Stroke length - the total linear travel distance of the actuator. (mm) Customizable
Components / BOM
  • Linear rail
    Provides a hardened, precision ground track for the carriage to travel along, ensuring straightness and load support.
    Material: Hardened steel
  • Carriage block
    Moves along the rail, contains recirculating ball bearings for smooth motion, and provides mounting points for the actuator rod or load.
    Material: Hardened steel or aluminum alloy
  • Actuator drive mechanism (e.g., ball screw)
    Converts rotational motion from a motor into precise linear motion of the carriage.
    Material: Hardened steel
  • End supports/bearings
    Support the ends of the actuator screw and rail, ensuring alignment and absorbing axial loads.
    Material: Steel with bearing-grade inserts
