Product Specifications

Technical details and manufacturing context for Actuator (Motor, Hand Crank, or Pneumatic Cylinder)

Definition
An actuator is the power source component within a height adjustment mechanism that generates linear or rotary motion to change the vertical position of equipment or work surfaces. It can be electrically powered (motor), manually operated (hand crank), or pneumatically driven (pneumatic cylinder), providing controlled movement for precise height positioning. The actuator is selected based on the required lifting force, stroke length, operating speed, and environmental conditions. Typical parameters include rated torque from 50 to 500 N·m (per ISO 5210), stroke length from 100 to 1000 mm, operating speed from 5 to 50 mm/s, and positioning accuracy of ±0.1 mm. Electric motor versions typically operate on 24 V DC (±10%) with power consumption from 50 to 500 W at rated load. The operating temperature range is -20 to 60 °C, and ingress protection is rated IP54 to IP65 (per IEC 60529). Housing materials may be aluminum or stainless steel, with stainless steel recommended for corrosive environments. Weight ranges from 5 to 50 kg depending on size and material. The actuator may be constructed with steel, aluminum alloy, plastic components, and copper windings (for motors). It is essential to verify model-specific values and standards with the legal manufacturer or supplier before selection or installation.
Working Principle
The actuator converts electrical energy (motor), manual force (hand crank), or compressed air energy (pneumatic cylinder) into mechanical motion through rotational or linear displacement. This motion is then transmitted to the height adjustment mechanism via linkages, gears, or direct connection, enabling controlled vertical positioning. The specific conversion method depends on the actuator type: a motor uses electromagnetic forces to rotate a shaft, a hand crank applies manual torque, and a pneumatic cylinder uses compressed air to move a piston linearly. The resulting motion is used to drive a lead screw or other transmission element, which adjusts the height of the equipment or work surface.

Frequently Asked Questions

What types of actuators are available for height adjustment?

Actuators for height adjustment can be electrically powered (motor), manually operated (hand crank), or pneumatically driven (pneumatic cylinder). The choice depends on the application's power source, control requirements, and environmental conditions.

How do I select the right actuator for my application?

Selection should be based on required lifting force, stroke length, operating speed, positioning accuracy, and environmental factors such as temperature and ingress protection. Refer to the manufacturer's specifications and verify that the actuator's rated torque and other parameters meet your needs.

What is the typical operating temperature range?

The typical operating temperature range is -20 to 60 °C. Outside this range, performance may degrade. Always confirm the specific temperature limits with the manufacturer for your model.

What ingress protection rating should I consider?

Ingress protection ratings range from IP54 to IP65. IP65 is recommended for dusty or wet environments. Verify the required rating based on your installation location and consult the manufacturer's documentation.
