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.

The ball casters are great swivelers and quite snazzy looking, too. Seen on your better chairs everywhere. These are brass plated on 1-1/2" square mounting plates with 3/16" holes at the corners. 2-1/2" dia.

These translucent silicone O-rings are 3/32" thick and measure 4" dia. Nice belts for science-project motors and even nicer for our slingshot needs. Crafters will see jewelry material that the metal-detectors won't care about.

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.

The sheaves, or wheels are about 2” dia x 1/4” wide, with a “V” groove that looks perfect to handle 1/8” or smaller Venetian blind cord. These dudes are perfect for demonstrating mechanical advantage in the physics lab!! But not for heavy lifting.
