Notes on this data
GAP: public pages read give no force, stroke, speed, voltage, IP or temperature figures; the brochure PDF (Stepper_Motor_Linear_Actuators_bruk.pdf) failed to fetch and other downloads require sign-in. Frame sizes and lead range are for the whole MLS/MLN/MLA family. Side load up to 10% of axial capacity. Marked verified=false because no performance figures were confirmed; application wording is not from the manufacturer.

Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Thomson part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
12/24 VDC acme leadscrew push/pull actuator with internal gearbox and built-in limit switches, for light-industrial, mobility and furniture automation.
View G-Series Leadscrew Linear Actuator →Worm-gear acme screw DC actuator rated 6,000 N push with aluminium housing and stainless rod, for lifting beds, wheelchairs and automation.
View GT44 Linear Actuator →Compact 12/24 VDC acme screw actuator with powder-metal gearing in five ratios trading force (300-2,000 N) against speed.
View GD Geared Linear Actuator →Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
