These casters popped right onto my old, but still great, Steelcase office chair. I had searched all over the web - sent photos to one company who continued to insist that I needed casters with the pins in them! Steelcase wanted over $100 for replacements. Thanks to Master Mfg. I saved a bunch.

I have a 25 year old steelcase desk chair with stems that are 7/16" wide and 1 1/4" long. These wheels fit perfectly.

For my chairs, the casters ride on the plastic rim causing the wheels not to swivel at all . These types of casters are limited so there are not a lot of choices out there to replace.
