Hi, diskullman.
Early on, we tried plastic bearings (delrin with glass balls). Unfortunately, they failed when the balls shattered. I will check the website you posted...perhaps we can revisit this.
Wheel bushing is zircon-toughened alumina, 4 inches in length.
The shaft has to be 1 inch O.D. and 18 inches long. The bearing (journal) surface is 4 inches. The shaft supports TWO wheels (side-by-side). A 4 inch long cylindrical spacer separates the bushings. The load on each wheel is 60 lb...
Thank you, MikeHalloran and unclesyd, for your quick replies. The woodexbearing.com web-site has hardwood bushings we can use.
Any suggestions for the non-rotating axle, which has to be 18 inches long and completely nonmetallic?
Greetings, fellow engineers!
I am seeking advice for our application, which is a completely nonmetallic wagon carrying an electromagnetic transmitter/receiver system. The current wheel bearing assembly has failed. It consists of zirconia-toughened alumina (AZT) bushings (~ 4" long, inserted into...
