Long stroke, low-noise linear actuator

As industry focuses on the working environment Danaher Motion have launched a new and improved Movopart range that has a very low operational noise profile.

This new low noise range has also claims increased in product life and for the first time the facility to adjust slide-bushing play.

Producing long screw driven linear drives presents a number of technical challenges to the design engineer.

This particular solution is ideal for applications requiring high force and low speed but all too often belt drive units are specified as long screw driven units were previously unavailable.

Screw supports have been designed by Danaher Motion to reduce the unsupported length of the screw as the maximum speed of the screw depends on the free length of the screw.

When the screw is rotating it can only withstand a certain speed at a certain length.

If this speed is exceeded the screw will begin to warp, ie the screw has reached its critical speed for that length.

To help the specifying engineer Danaher Motion has produced some sizing and selection software that clearly predicts when screw supports are needed.

The Linear Motion Systems division of Danaher Motion, provides standard and custom linear bearings, linear guides, ball and lead screws, gearheads, linear actuators, slides and systems, precision balls, moulded products, resolvers and feedback devices, brakes and clutches.

Its products are applied worldwide throughout a variety of motion applications in the medical, industrial, aerospace, and mobile off-highway markets.

Its highly recognised brand names include: ThomsonT, Thomson BSAT, MicronT, HaroweT and Deltran PTT.
