Most of them, and sundry rotating wing masts we have built have had plain plastic bearings at a couple of hundred bucks each, and then used as moulds for an epoxty ring around the mast. We did build a spherical ring bearing with plastic bearing for a wing mast rig, cost a couple of grand.
For a wing rig, it would need to be less friction than either of these, I think, unless some dampening is required. Less friction implies roller elements, occasional greasing and either stainless shells or regular maintenance. Plenty of these available for industrial equipment or off the shelf.On Sat, Jan 23, 2016 at 3:53 AM, robriley@rocketmail.com [harryproa] <harryproa@yahoogroups.com.au> wrote:
