PBC launches range of miniature linear actuators

A PBC Linear product story
Edited by the Engineeringtalk editorial team Oct 22, 2009

PBC Linear has launched the ML series of miniature linear actuators.

This new range suits small-scale automation markets, such as laboratory, medical and packaging applications.

Lightweight and compact, measuring 28 x 32mm, the ML series of mini actuators is designed for single- and multi-axis assemblies.

Launching with three new actuating styles - MLB, MLC and MLD - the ML series lets the customers choose the configurations that best suit their application.

The MLB comes complete with a motor for powered, automated control.

The MLC features a motor mount for coupling to a motor of the customer's choice.

The MLD has a hand-turned knob for precise, manual control applications.

The ML series features several design improvements that promote high performance, precise travel and power, according to the company.

The outer body profile is precision-machined using PBC Linear's patented Simo process.

The Simo process gives the actuator concurrent and consistent machining on all critical edges, ensuring tight tolerances and high-accuracy mounting.

It also reduces weight, allowing for a smaller motor to drive the actuator.

The ML-series 'dovetail'-style carriage comprises 14 plane bearing surfaces, supporting low friction, smooth motion and quiet travel.

Optional single or dual external linear guide supports can be added for enhanced stability and load capacities.

Internally, the ML series of mini actuators is built for performance; with a larger-diameter lead screw, the ML series can support higher load capacities at greater accuracy.

Duplexed lead screw support bearings provide high stiffness, increased thrust load and repeatability.

An optional anti-backlash nut is also available on the ML series for applications that require high bi-directional accuracy.

The lightweight ML series, with its precision-machined outer profile, can fit onto any axis.

Motors can be mounted inline on the side, top or bottom of the actuator as space permits.

This is a benefit when implementing a multi-axis design.
