Stem-mounted caster set

This set of five 3-inch stem-mounted casters replaces the original wheels on most office and gaming chairs. Each caster uses a 7/16" x 7/8" stem that pushes into the chair base without tools. The black polyurethane tread rolls on hardwood, laminate, tile, vinyl and carpet without marking.

Who these suit and who they don't

They suit anyone wanting quieter movement and floor protection on standard chairs that accept the 11 mm x 22 mm stem. They do not fit IKEA chairs or any seat that uses a different stem size, a plate mount or a threaded stem. Buyers needing a larger diameter or a locking brake should look elsewhere.

Load capacity per set

The five casters together support up to 650 lbs, so the set handles heavy users and long daily sessions. The precision ball bearings and steel brackets keep rolling resistance low while maintaining that rating. Check your chair’s stem dimensions before ordering.

Questions about this item

What stem size must my chair already have for these 3C11 wheels to fit?

Your chair needs a standard 7/16" x 7/8" (11mm x 22mm) stem mount for these wheels to install correctly.

Will these 650 lbs rated casters damage the hardwood floors my older chair currently rolls on?

No, the soft polyurethane tread is non-marking and safe for hardwood, laminate, tile, vinyl, and carpet without a mat.

How can I verify the precision ball bearings are rolling silently after I push them in?

Roll the chair on a hard floor; you should hear near-silent movement with no grinding or friction noise.
