DRIVES & WHEELS

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" version is rated for a 300lb. load and the 12" (round) for 1000lbs.

Good-bye backaches. Save your sacroiliac with a 3-wheeled professional mover's dolly. It measures 6-3/8" wide between a trio of swivel casters with 1-9/16" x 11/16" wheels, and has a drop-down center and a 1/2" dia hole for permanent attachment to frequently moved items. Steel construction, 110 lb max load (so not piano-duty), and rubber pads above each wheel. Stands 2-1/2" tall. We think ordering (4) would be a good place to start.

These light-duty plastic casters are on swiveling stems and have dual 1-1/2" dia x 5/16" wheels in 1-7/8" x 1-3/16" hemispheric housings. Stems are striated steel, 3/8" dia x 3/4" long. We're thinking these would be fine for your average chair. Our each is a bag of (4).

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’re on a roll. You’ve been on a roll for years and you know it. Keep it going with this set of (6) 5/8" dia steel ball casters on 2" x 1-3/8" plates with 5/32" mounting holes. Rated for a max load of 35 lbs, and come on, you’ve got a million things under 35 lbs that need rolling.

This rope hoist has drop-forged, zinc-plated eye-hooks and claims to be rated for a 2,000-lb working load, but we think that's a misprint. Great for easily hoisting lumber and pails of gravel, but leave your grand piano on the first floor, or hire the professionals. The eye-hooks are 2" x 1-3/8" x 1/4" ID, and the nylon triple pulleys provide a 7:1 lift ratio. Includes (65) feet of 1/4” dia nylon rope.

These small swivel plate casters have dual 1-3/8” dia plastic wheels on coincidentally 1-3/8” square mounting plates with (4) holes.

They have a little dirt on the wheels that cleans up nicely with some soap and water. That's Surplus for ya'.

Just a real soft name for a hunk of cast iron that holds a sealed bearing.
