Part # SSRAI3026ZKERA5P36L02P They cost around US$75.00 each and you will need two. James Quote Link to comment Share on other sites More sharing options...

Premium Members Peter Abraham Posted February 17, 2004 Premium Members Report Share Posted February 17, 2004 If you're going to do it yourself, might I recommend these steps? 1. Set out all parts on some cloth. 2. Have a plastic tub with denatured alcohol in it, about 4 inches deep. 3. Have Teflon Oil in a needle-applicator tube handy. 4. Have both bearing races out and ready to be inserted. 5. Have a pencil and paper handy, and draw roughly the ORDER in which you are removing items. Things must go in of course, just as they came out. No extra parts can be left over at the end of this........ :unsure: Then... 1. Pull the top of the gimbal off by using a spanner wrench to loosen the upper cap. 2. Draw off the outer shell and remove the two bearing races. They're garbage. 3. Using a clean lint-free cloth soaked in denatured alcohol, RUB all around the inside of the gimbal, cleaning out all lube and bits of dirt. 4. Drizzle a few drops of the Teflon Oil into the bearing, as you hold it on your fingers. The way that seems to work best is to insert two fingers inside of the bearing race, and spread them to hold the inside ring- kind of making a "V" or Peace Sign for those ex-hippies in the audience. 5. Then, drizzle just 3 or 4 drops into the upper edge of the bearing race and spin the outer ring around, spreading the lubricant as it oozes down into and against the ball bearings themselves. 6. Immediately set the bearing races down into the freshly cleansed gimbal inner area. 7. NOTE: These are precision fit items. They WILL come out easily if pulled up straight, and they WILL go back in if they are inserted dead vertically. You need to take some care not to force them, for if you bend any part of one of the bearing races, you're dead in the water. Just push them down firmly but carefully in a straight down motion, and you will be good to go. 8. Gently re-turn the gimbal top cap with your fingers. It's a fine-thread item and can cross-thread easily. God help you if it does. Then, tighten down at the end with spanner wrench. If you cannot score the right spanner wrench, two tiny jeweler's screwdrivers held just so, will do the trick in a pinch. Wipe down the outside of the gimbal and yoke well with denatured alcohol- it's very likely to have gotten a bit of the teflon oil on it. Congratulations ! You're a Gimbal Service Engineer now !!!

Matthew Hutchens Posted May 26, 2012 Report Share Posted May 26, 2012 Does anyone have a supplier for these? I'm not having any luck finding the part number online. Thanks Quote Link to comment Share on other sites More sharing options...
Premium Members Joe Lawry Posted March 14, 2013 Premium Members Report Share Posted March 14, 2013 Im trying to replace the bearings in my 3a gimbal as well. That part number above has not helped me. I've been asked by the supplier what size the bearing is, does anyone know? it obviously has a larger inside diameter than 1.5".. I am currently busy on a job and dont have time to pull my gimbal apart otherwise i'd just take it in to the bearing supplier.

Premium Members Thomas Crescenzo Posted March 20, 2013 Premium Members Report Share Posted March 20, 2013 Based on an EFP bearing, it looks like 1.625" x 1.875" x 0.155" 1 Quote Link to comment Share on other sites More sharing options...
Premium Members Peter Abraham Posted June 16, 2013 Premium Members Report Share Posted June 16, 2013 They used to be available from New Hampshire Ball Bearings. Try them ! nhbb.com Best, Peter Abraham, S.O.C. Quote Link to comment Share on other sites More sharing options...
Premium Members Peter Hoare Posted June 28, 2013 Premium Members Report Share Posted June 28, 2013 Its likely a size made by Kaydon or Silverthin. If you need two of them im guessing they are angular contact bearings... Kaydon and Silverthin have a pretty big catalogue of sizes, its bound to be in there somewhere... If you can get the old bearing out and measure it up, there will likely be an alternative available. Be careful though as the Kaydon and Silverthin bearings in one off quantities are very expensive and could take a few months to arrive... Pete.
