Mid-America Manufacturing offers adjustable workpiece supports that are designed to withstand heavy loads. The compact devices, which are made of Stressproof 1144 steel and feature Acme-style threads, can support as much as 40,000 lbs during machining operations.
The adjustable supports can be used vertically or horizontally and are offered in four sizes ranging in heights from 2" to 24". Such adjustability allows faster setups by eliminating the need for shimming. Jam nuts allow them to be locked into the correct height after set up for repeatable part fixturing. The supports are available with flat, spherical, wedge, V-notch or 90-degree, pointed workpiece contacts in addition to 8" and 12" clamp bars.
