Premium Members DavidWest Posted December 23, 2007 Premium Members Report Share Posted December 23, 2007 any help appreciated... i have an efp sled and gimbal<---(which i hesitate to take apart) a also have a 3a sled but it did not come with a gimbal. despite all warnings, i want to try and make one for it mostly just to see if i can. my question is how many pan bearings are being used in the two inch gimbals? i can see rational for using one in that you could avoid the complex alignment problems that two bearings present; however, two bearings could much more easily support the extreme loads that are presented when riding in a vehicle, etc... is this TOP SECRET, or can someone tell me if one or two pan bearings are more common in the 2inch gimbals? thanks, david Quote Link to comment Share on other sites More sharing options...
TJ Williams Posted January 19, 2008 Report Share Posted January 19, 2008 hey 1 or 6 would be both ok more bearings distribute the load better but have more turning resistance. If your machining isn't accurate enough to align two bearings you should rethink trying to make one as it will never even static balance.

My machining is accurate enough to do six, but machinging aside, most bearings that go into an application in pairs are shipped in pairs from the mfg. I'm not sure why, but probably so that even the slightest mistolerances arent doubled. If i did use six i am also afraid that the housing for all six would limit my upper and lower limits. (i do understand the pun of six, but at the same time the logic still applies) i will probably go ahead and use two since i have bearings that came in pairs. ill let you know how it comes out TJ since you were the only response out of so many views... cheers dbw Quote Link to comment Share on other sites More sharing options...
chuck colburn Posted January 19, 2008 Report Share Posted January 19, 2008 If I was designing my own gimbal I would use a pair of the first two listed bearings for the pan and the third listed one for the tilt bearings as they would be self aligning and make for easier fabrication. http://www.thk.com/us/products/class/cross...roller_r_a.html http://www.kaydonbearings.com/catalogs/Catalog311.pdf#page=3 http://www.globalspec.com/FeaturedProducts..._Bronze/18112/1 Quote Link to comment Share on other sites More sharing options...
