Never seemed fair to nail the "lazy" tag so permanently on the "Susans" but that probably has no "bearing" on the issue. Also called turntable bearings, they are the square or circular flat ball bearing devices YOU bolt between two flat objects to achieve rotation. Like that spinning center section of a Chinese restaurant table. We had these in surplus once and they were quite popular. To our chagrin, we discovered they could be bought commercially for the same price. So we did. The 4" square version is rated for a 300lb. load and the 12" round for 1000lbs.

Just a real soft name for a hunk of cast iron that holds a sealed bearing. This one measures 3-1/4" wide x 2-3/4" tall x 1-3/4" with a pair of 3/8" mounting holes in the bottom and a 1-15/16" sealed bearing with a 1" ID x 1-3/8" dia x 1-11/32" long bushing with two setscrews to hold a lube-fitting on top.

That's what these nylon bushings were made for, but they're suitable for anything that could use a little bushing. Our middle-sized measures 15/16" dia x 15/32" thick with a 3/8" bore and a slight taper.

Interesting concentric sealed bearing, like a pillow block, from Hub City. The outer portion measures 52mm dia x 15mm thick with an anti-rotation pin, and the inner measures  34mm dia x 12mm thick with a 22mm ID bore and (2) 3mm setscrews.

These pillow block bearings have 13-gauge steel mounting straps, 4" long x 1-1/8" with 5/16" x 5/8" mounting slots, and a sintered iron ball unit measuring 1-11/16" dia with either a 5/8” ID or 1” ID brass sleeve. The 5/8” ID one has an oil cup on the top; the 1” dia version has a grease fitting in the same place.

You pick: the sleeved bearing, sometimes listed as a "special agricultural bearing," is a single race radial bearing, 1-9/16" OD x 5/8" ID x 3/4" with a black plastic sleeve surrounding it, measuring 1-13/16" x 1" with a 1/16" wall; the booted bearing measures 1-1/2" OD x just shy of 11/16" ID x 1/2" thick, inside a 1-13/16" black rubber boot with a removable hex ID bushing.
