Designed for laboratory and industrial automation, PBC Linear's MLA mini-actuator is built for tough industrial applications and for precision in the lab.
This actuating system is the latest addition to PBC Linear's line of linear actuator technology (LAT), which has been shown to carry greater load capacities and travel at higher speed with increased precision.
The MLA is 28mm wide, is offered in varying lengths and weighs 0.15kg/100mm.
With the system's integrated screw nut composed of PTFE impregnated polymer and six bearing plane surfaces per side, PBC said the MLA nearly doubles the potential load capacity for any miniature actuator design.
The MLA carriage comes with a dovetail-shaped mount that aids alignment and increases accuracy of part positioning during assembly.
The dovetail mounting design also lends to the actuators high-speed capabilities, which is further facilitated by a large lead screw.
The MLA mini-actuator's compact motor mounting adaptor allows the pairing of standard stepper and servo drive motors while minimising overall length.
Mounting the actuator is done by using clamps on the integral dovetail-shaped slots located along each side close to the base.
Limit switches and other accessories are mounted to the T-slots that are accurately positioned along each side of the actuator.
The carriage has two threaded inserts to ensure dependable mounting to the carriage.
The MLA is offered with customisable options, both in mounting capabilities and design functions, such as several different sizes of drive screws.
With the possibility of having up to two profile rails, moment capacity for the MLA is increased.
Also, to allow for function in contaminated and cleanroom environments, a seal strip can be added to keep dirt and grime out of the system, while keeping all particulates from exiting the system.
From gear reducers to stepper motors, the MLA can be tailored to meet any compact linear motion application.
Backed by its SIMO process, PBC Linear is able to precision machine the MLA mini-actuator in minutes.
The SIMO process provides consistent accuracy and precision along all edges throughout the entire extrusion.
