Bidirectional Transfer Device provides a practical low-cost method for automatic work positioning. The unit is extremely compact and eliminates the need for complex, expensive work positioning mechanisms. The DURA-TRANS unit that provides the horizontal motion has been tested under actual operating conditions with up to 160 million inches accumulated travel with negligible wear.
The main blocks on both sides move on slide bearings of oil impregnated bronze bushings which eliminate the need for relubrication. Bronze bearings are utilized rather than linear ball bearings because the bushings distribute the load over a larger surface area. This results in infinitely less wear on the slide rods. All rods are pinned to the end blocks to assure positive fastening. The nylon bumper on the main slide contributes to a low noise level to minimize the clatter inherent in fast acting slide devices.
DURA-TRANS units can be mounted in any plane with the main block in the main slide used as the support. The end block is provided with tapped and drilled holes for mounting appropriate stripper tooling.
