50 mm PU Twin-Wheel Casters with 11 mm Stem

These 50 mm polyurethane twin-wheel casters rotate 360 degrees and carry 25 kg each. The 11 mm by 22 mm grip-ring stem fits standard office-chair bases. Five white wheels arrive ready to replace worn or noisy originals. Smooth rolling protects both hardwood and carpet without leaving marks.

Ideal for swapping hard plastic wheels on home

Buyers who want quiet, floor-friendly mobility on standard 11 mm stem sockets will benefit. Chairs with larger-diameter stems, threaded stems, or top-plate mounts cannot use this set. Very heavy seating that exceeds the 25 kg per-wheel rating should look at higher-capacity alternatives.

The 11 mm by 22 mm grip-ring stem decides fit

Measure the existing stem diameter and length before ordering; only an 11 mm diameter and 22 mm length match this caster. A different diameter or a longer shaft will not seat correctly. Confirm those two figures and the 50 mm wheel height to ensure proper installation.

Questions about this item

Should I choose the 5-piece set or buy them individually?

The product is sold as a set of five casters, each rated for 25 kg, so one pack covers a standard five-star chair base.

Will the 55 lb per-wheel rating hold up on a typical office chair?

Yes, each caster supports 55 lb, giving a combined capacity well above the weight of most office chairs and occupants.

Does the 11 mm stem fit the standard sockets on my chair?

The casters use an 11 mm diameter by 22 mm long stem, which matches the common office-chair socket size.
