Technical details and manufacturing context for Linear Actuator

Definition
Within an Automated Extraction Mechanism, the linear actuator serves as the primary motion component that physically engages with and extracts materials or products from their positions. It provides the controlled linear force necessary for the extraction process, ensuring precise positioning and consistent operation.
Working Principle
Typically uses an electric motor to rotate a lead screw or ball screw, which converts rotational motion into linear movement of a piston or rod. The actuator's extension and retraction are controlled through electrical signals to position the extraction tool accurately.
Common Materials
Aluminum alloy housing, Steel lead screw/ball screw, Bronze or polymer nuts, Stainless steel piston rod
Technical Parameters
  • Stroke length - the maximum linear travel distance of the actuator (mm) Customizable
Components / BOM
  • Motor
    Provides rotational power to drive the screw mechanism
    Material: Steel and copper windings
  • Lead screw/Ball screw
    Converts rotational motion into linear movement
    Material: Hardened steel
  • Nut
    Travels along the screw to create linear motion
    Material: Bronze or polymer
  • Piston rod
    Extends and retracts to perform the extraction action
    Material: Stainless steel
  • Limit switches
    Detects end positions to prevent over-travel
    Material: Plastic and metal contacts
Engineering Reasoning
0.1-35 MPa hydraulic pressure, 12-48 VDC electrical input, -40°C to 120°C ambient temperature
Seal failure at 40 MPa hydraulic pressure, motor burnout at 55°C winding temperature, ball screw deformation at 450 MPa stress
Design Rationale: Seal extrusion failure due to exceeding 40 MPa yield strength of HNBR elastomer, copper winding insulation breakdown at 155°C Class F rating, ball screw plastic deformation at 450 MPa yield strength of 4140 steel
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Spool valve sticking causing position control error exceeding ±0.1 mm tolerance
Strategy: Install 3 μm absolute filtration with differential pressure monitoring at 0.35 bar warning threshold
Trigger Backlash accumulation exceeding 0.05 mm in ball screw assembly
Mode: Positional hysteresis causing ±0.3 mm repeatability error
Strategy: Preload adjustment to 5% of dynamic load capacity with laser interferometer verification at 0.001 mm resolution

Frequently Asked Questions

What is the difference between lead screw and ball screw in linear actuators?

Lead screws use sliding contact for cost-effective precision, while ball screws use rolling elements for higher efficiency and speed, making them ideal for demanding industrial applications.

How do I select the right linear actuator for my machinery application?

Consider load capacity, speed requirements, stroke length, duty cycle, and environmental conditions. Our actuators offer customizable specs including motor type, screw selection, and housing materials.

What maintenance do industrial linear actuators require?

Regular lubrication of screw mechanisms, inspection of limit switches, and cleaning of piston rods. Our aluminum/stainless steel construction minimizes corrosion for reduced maintenance in harsh environments.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
