Air bearing test turntable, motion simulator, rotary, T-900 spacecraft satellit

Description: Air bearing test turntable, motion simulator, rotary, T-900 spacecraft satellit This is a used rotating air bearing test table for providing a nearly torque-free spinning platform for testing spacecraft, instruments or avionics. The unit is made up of a very heavy cast iron base, spindle assembly, slip ring, drive motor, and table assembly. The pedestal base supports the turntable section with a u-shaped cradle. Turntable section can rotate in the cradle to change the angle of the spinning axis. A slip ring with approximately 60 conductors is built into the rotating assembly for powering the test specimen. Drive power comes from a special motor which is integral to the lower portion of the spindle assemble. Motor has multiple poles and sets of conductors as can be seen in the photos. The mounting surface is a 1 3/4" thick steel plate which is mounted atop of a 1 3/8" thick glass plate. This is a highly specialized unit that was built to the highest standards and would require a fair amount of knowledge to operate. Dunn Engineering and Wayne George are the manufacturers on the nameplate but they do not appear to be in business anymore so support will be solely on the buyer. There is a crack on the thinner section of the casting near a hand wheel but this is not part of the main structure. The handwheel will also need to be replaced. The turntable cannot be turned by hand although it is not known if there is an internal brake or gear reducer that could be impeding the rotation. We have another one of these units as well.

Our company return policy is that our description is guaranteed and we will accept returns in the event an item is mis-described. When communicating with us please use your own email address. We want to know who we are communicating with and we cannot identify specific emails in our inbox using the ebay email system. Send emails to heritageequipment AT gmail . com The new ebay buyer protection program has inspired us to offer all of our items “as-is”.This does not mean that you are buying a machine with deficiencies, known or unknown. What it means is that some of our items will be tested and will include the results in the description and others will be untested but described accurately to the extent that is possible without actually powering up the machine. In addition to this written description you will have the opportunity to view high quality photos of the item. With these two sources of information you will have as much information as possible without being physically here to inspect the machine. Feel assured that we will make a diligent effort to give you an accurate description of the equipment. As a buyer you should be aware that you are buying an expensive piece of equipment at a greatly reduced price and as such you may have to deal with certain unknowns and defective components which were not known and could not be known without full scale setup and operation of the machine. Our experience in dealing with many specialized pieces of equipment has proven this to be a rare occurrence however it is a risk inherent in buying used equipment. The very few times we have had to deal with these issues we have been very helpful in resolving the problem.
