Universal 11x22mm Stem Fit

These 75mm caster wheels use a standard 11x22mm stem with a 24mm base that fits 99 percent of office, gaming and home chair bases. The Metra set of five replaces worn plastic wheels in minutes without tools. Builders who need plate-mount or side-mount stems cannot use this product.

650lbs Total Load Capacity

Four precision bearings and polyurethane construction give the five-wheel set a combined 650lbs rating, enough for heavy users and long daily sessions. The 360-degree swivel keeps movement smooth on hardwood, tile, carpet and laminate without a chair mat. Buyers who need a set rated above 650lbs must look elsewhere.

Snap-In Upgrade From Hard Plastic

Pull out the old casters and push these in until they lock; the polyurethane tread eliminates floor scratches and runs silently compared to standard hard plastic wheels. The jump is worth it when your current wheels mark floors, bind on carpet or make noise. Chairs with non-standard stem sizes or integrated wheel bases will not accept this upgrade.

Questions about this item

Will the 11x22mm stem on these 3 inch casters fit the chair base I already have?

The 11x22mm stem with a 24mm base is designed for universal fit with 99% of office and gaming chairs, so it will match most existing bases.

How can I confirm the 360 degree swivel and floor-safe polyurethane are performing correctly after installation?

Roll the chair across wood, tile, carpet and laminate; the wheels should glide silently without scratching and rotate freely in every direction.

What comes in the box and is any extra hardware needed for the 5 pack of stem mount casters?

The set includes five complete 3 inch casters; the snap-in stem design requires no tools or additional parts for installation.
