OVERVIEW
These linear actuators are electromechanical devices designed for push and pull forces in wide-ranging industrial applications.  Small actuators with ratings as low as 200N can have DC or AC motors.  Medium to large actuators with forces up to 350kN are generally powered by AC motors.  Speeds range from 1 to 875 mm/s with the highest ratings achieved by ‘U’ shaped actuators such as the UBA.  High speeds and high precision positioning are often achieved with servo motors.

Standard actuator strokes are from 100 to 1500mm.  In push applications the stroke may be limited by buckling limits.  Special designs with non-standard strokes, fittings, motors, etc are possible for volume applications.  Actuators are available optimised for solar tracking of photovoltaic panels.

These actuators are manufactured by Servomech and Linear-Mech, Servomech is a specialist and leader in industrial linear motion, founded in 1989.  They manufacture acme screw and ball screw models.  Linear-Mech are a subsidiary of Servomech that specialises in smaller linear actuators with DC motors typically up to 9A current and AC motors typically up to 120W.  Lenze/Techdrives has been responsible for UK sales and technical support for 20 years.

Correct sizing of linear actuators involves speeds, forces and considerations of mounting, control, duties and operating environment.  We recommend that use is made of our enquiry sheets which can be downloaded from the product pages.

ACME THREAD LINEAR ACTUATORS TYPE ATL

Forces to 350kN, speeds 1 to 140 mm/s,  motors ac,dc or servo, duty 30%.  General purpose actuators for medium to high forces.
Wide range with strokes up to 1500m.

LIGHT DUTY LINEAR ACTUATOR TYPE LMR

Forces to 6000N, speeds 5 to 50 mm/s, motors 12V DC or 24V DC, duty 15%.  Integral limit switches. These actuators suit small machinery, food preparation, agricultural machines and switchgear.

SMALL DC & AC LINEAR ACTUATORS TYPE ATL &
BSA 02-12

Forces to 11000N, speeds 6 to 150 mm/s, motors 230V AC or  12/24V DC, duty rating 15% for ATL, 100% for BSA.  Suits guides & positioning on industrial machinery.

Techdrives brings to the UK the widest range of industrial electric linear actuators supported by the expert advice of our engineers.  Linear actuators lift, tilt, push, pull & adjust.  Manufactured by Italian specialist and sister companies Linear-Mech (smaller sizes) and Servomech (larger sizes, also screwjacks & ballscrews), actuators have DC, AC 1 & 3 phase or servo motors.  Forces start at 100N and go to 35 tonnes. Linear speeds range from very slow to 1.5 m/s.  Compared to hydraulic & pneumatic cylinders, electric linear actuators are much easier to control, do not cause annoying leaks and can be up to 90% more efficient.
