Product catalog summary
Product Overview
Linearmech electromechanical linear actuators are designed to convert rotary motor movement into linear motion, suitable for push or pull loads. They are reliable, low-noise, and easy to install, serving as alternatives to pneumatic and hydraulic cylinders. Key features include self-locking for position holding, energy efficiency, and safety in extreme temperatures. Manufactured in Italy, they ensure high quality and quick delivery.
Actuator Range
The range includes Acme screw and Ball screw linear actuators. Acme screw actuators come in various series with different load capacities and speeds, while Ball screw actuators offer higher duty cycles and precision. Gearmotors for rotative actuators are also available.
Manufacturing Features
Actuators are made with high-quality materials like aluminum and steel, ensuring durability and precision. The manufacturing process includes rigorous quality checks. Components such as worm gears, timing belts, and ball screws are designed for high performance and efficiency. Larger actuators use self-lubricating bronze bushes to reduce friction.
Selection Criteria
Selection depends on load capacity, speed, duty cycle, and environmental conditions. Linearmech offers customizable solutions to meet specific application needs. Considerations include stroke, load type, linear speed, duty cycle, motor type, accessories, and environmental conditions.
General Features
Ball screws and Acme screws are used for different applications, with specifications for static and dynamic self-locking conditions. Both DC and AC motors are available, featuring electronic overload protection and dynamic braking.
Installation and Commissioning
Installation requires only power and control cables. Linearmech provides support for technical calculations and certifications. Proper alignment is crucial to prevent power loss and malfunctioning.

  • MR 40 FC Gearmotors: Includes stroke end switches for turn control and a rotative potentiometer for positioning control.
Ball Screws: Features rolled ball screws with low axial backlash and options for zero backlash or preloaded configurations. Load and lifetime diagrams assist in selecting the appropriate ball screw.
Self-locking Conditions: Describes static and dynamic self-locking conditions, emphasizing the use of brake motors in certain scenarios.
Motors:
  • DC Motors: Available with interchangeable and non-interchangeable brushes, offering various power and protection classes.
  • AC Motors: Detailed specifications for different actuator models, including power, poles, voltage, and current ratings.
Stroke End Switches and Positioning Control: Magnetic and electric stroke end switches are described, with guidelines for installation and connection to control circuits.
Specifications and Components: Details the specifications and components of linear actuators, focusing on the LMR, CLA, and CLB series. Describes electric stroke end switches used to control actuator lengths.
Positioning Control: Achieved through electric cam-operated stroke end switches and rotative potentiometers, providing an analog output signal proportional to the actuator's position.
Encoders: Two types of encoders are discussed: Encoder GI for LMR series and Encoder EH38 for ATL and UAL series.
Controls and Drivers: Introduces electronic overload protection and dynamic braking for DC motors. Drivers are programmable for single and dual actuator control, supporting various working modes.

¡¿UfW8P-MStí¡.j 1.1 LINEARMECH LINEAR ACTUATORS Linearmech electromechanical linear actuators are motorized mechanical cylinders able to transform a rotary movement of a motor into a linear motion. Able to work under push or pull load. Due to the mechanical resistance of their components, many actuators can support push loads higher than pull loads. Their main characteristics are the high performance reliability, with or without load, and the low noise level. Their installation is simple and not expansive: it requires just a front and rear hinging as for standard hydraulic They can effectively...

1.4 SELECTION CRITERIA In order to select the most suitable linear actuator, it is first necessary to analyse the application to determine the required performances and the working conditions. 1. Basic performances required § Stroke § Push or pull load § Linear speed 1 .1 The load and the linear speed, if considered separately, determine the required type of linear actuator to be selected; if considered as contemporaneous performances they determine the required power and, therefore, the actuator’s size. 1 .2 The stroke length may influence the selection of the actuator’s size only in case of...
