Medical Linear Actuator Systems for OEM Equipment

This page is the main selection entrance for GEMING medical linear actuator systems. It is intended for OEM hospital beds, home-care beds, treatment chairs, patient-handling equipment, rehabilitation equipment, and diagnostic platforms.

A complete system may include one or more electric actuators, a control box, a handset or nurse control, optional foot controls, an emergency-stop input, and battery backup. Final configuration depends on the equipment mechanism, load, stroke, speed, duty cycle, mounting geometry, control logic, cleaning conditions, and safety requirements.

1. Choose the actuator configuration

Compact medical actuator

For short-stroke, space-constrained mechanisms such as headrests, access panels, small positioning modules, and auxiliary adjustments. Start here when installation space and low moving mass are more important than maximum thrust.

Standard medical-bed actuator

For backrest, leg-rest, tilt, and other articulated bed or care-chair movements. Configurations can be selected by push-pull load, retracted length, stroke, speed under load, mounting direction, and control compatibility.

High-force medical actuator

For mechanisms with higher axial loads, including bed-height linkages, patient-handling equipment, and heavy treatment furniture. High-force selection must include the complete linkage geometry because the actuator force changes as the mechanism angle changes.

Dual actuator

For equipment that combines two movements in one integrated drive unit, such as back and leg adjustment in an electric bed frame. Confirm the required travel of each output, holding behavior, control-box compatibility, and manual or emergency release requirements.

2. Configure the medical actuator system

Configuration item Available direction What the OEM should provide
Actuator structure Compact, standard rod, high-force rod, or dual actuator Mechanism drawing and available installation envelope
Load class Low-force adjustment through high-force configurations up to 8000 N Running load, holding load, load direction, and linkage geometry
Stroke Short-stroke and extended-stroke options, typically 10-1500 mm depending on family Required travel, end clearance, and retracted length
Speed Approximately 4.5-150 mm/s depending on load and transmission Required travel time under the real operating load
Power 12 VDC or 24 VDC actuator options Available supply, peak current, and backup-power requirement
Protection IP43, IP54, or IP65 configurations depending on actuator family Cleaning method, liquid exposure, dust, and operating environment
Feedback Built-in limits and optional Hall feedback on selected configurations Position reporting, synchronization, and fault-detection needs
Controls Single or multi-actuator control boxes; handset, nurse, foot, or emergency controls Number of movements, user roles, lockout logic, and emergency behavior

Important: the maximum load, longest stroke, highest speed, and highest ingress-protection rating belong to different configurations. They must not be combined into one assumed product specification.

3. Select the control and user interface

  • Control boxes: select the number of actuator channels, output voltage, synchronization requirement, and overload or thermal protection.
  • Hand controls: simple two-button controls through multi-function bed handsets.
  • Nurse controls: multi-function panels for caregiver operation and function lockout.
  • Foot controls: hands-free adjustment for treatment and examination equipment.
  • Emergency controls: define emergency stop, release, lowering, and power-loss behavior at system level.
  • Battery backup: available where the equipment must complete a safe movement when mains power is unavailable.

4. Typical medical actuator applications

  • Hospital beds and home-care beds
  • Treatment and examination chairs
  • Patient lifts and mobility equipment
  • Rehabilitation and therapy equipment
  • Diagnostic and ophthalmic platforms
  • Medical carts and adjustable instrument modules

Review the wider GEMING Medical & Care application area, or compare the full electric linear actuator range when the mechanism needs a different form factor.

5. Start a medical configuration inquiry

Start with your equipment type, what needs to move, and your contact email. Select the number of powered movements, or choose “Not sure.” Unknown load, stroke and speed values can stay blank.

Helpful details for the engineering review, when available

  1. Equipment type and the movement to be powered
  2. Mechanism drawing with pivot and mounting coordinates
  3. Push, pull, holding, and expected side loads
  4. Required stroke, closed length, and target speed under load
  5. Cycles per hour, running time, rest time, and ambient temperature
  6. Voltage, number of actuators, synchronization, and feedback requirements
  7. Cleaning method, ingress-protection target, and operating environment
  8. Required handset, nurse control, foot control, emergency behavior, and battery backup

Share the details you already know through the medical configuration inquiry form. GEMING will review the equipment task and narrow the actuator system options for further engineering discussion.

Safety and compliance note

A medical linear actuator is a component of the final equipment. Suitability, risk controls, cleanability, electrical safety, mechanical safety, and regulatory compliance must be assessed and validated for the completed medical or care system. A component option should not be treated as system certification.

Frequently asked questions

What is the best medical linear actuator for a hospital bed?

There is no single best model for every bed movement. Backrest, leg-rest, tilt, and height functions can require different loads, strokes, speeds, installation lengths, controls, and emergency behavior.

Can one control box operate several medical actuators?

Yes, selected control boxes can operate multiple actuator channels. The number of channels, voltage, synchronization, handset functions, and fault behavior must match the equipment design.

What information is needed before selecting an actuator?

For an initial review, describe the equipment and movement, then provide a contact email. During engineering selection, share any available mechanism drawing, load, stroke, closed length, speed, duty cycle, voltage, controls, mounting, cleaning and fault-response requirements.

Can the maximum load, stroke, and speed be selected together?

Not automatically. Force, speed, screw lead, motor, stroke, retracted length, duty cycle, and protection level are configuration-dependent and must be checked together.

Medical Linear Actuator Configuration Guide

Family Primary selection purpose Typical configuration range
Compact actuator Short-stroke auxiliary adjustment in limited space Low-force, short-stroke, high-speed options
Standard medical-bed actuator Backrest, leg-rest, tilt, and care-chair movement 12/24 VDC; configurable force, stroke, speed, limits, and feedback
High-force actuator Bed-height linkage, patient handling, and heavier treatment furniture Up to 8000 N depending on configuration and mechanism geometry
Dual actuator Two integrated bed-frame movements Separate travel outputs with matched control system

Final values depend on the selected actuator family. Maximum values cannot be combined into one assumed configuration.

What should I send for initial selection?

Describe the equipment, the powered movements and the number of motors. Add any known load, stroke, closed length, voltage and control requirements. A mechanism drawing helps the engineering review.

Can the actuator, control box and handset be selected together?

Yes. Review the complete motion chain, including the motor count, voltage, input functions, feedback and required emergency behavior. Connector appearance alone does not establish compatibility.
