Universal 11mm Stem Fit

These five replacement casters use a 7/16 inch stem that measures 11mm in diameter. They are designed to fit most standard office chairs directly. The specifications note that IKEA chairs are not compatible, so buyers with that brand should verify stem dimensions before ordering.

140lb Per Wheel Load Limit

Each caster supports a dynamic load of 140 lbs, giving a combined capacity of 700 lbs for the full set. The construction uses a heat-treated alloy steel core with dual ball-bearing raceways. This rating defines the maximum weight the wheels can handle safely during daily movement.

Soft PU Tread Protects Floors

The polyurethane outer layer is engineered to prevent scratches on hardwood, laminate, tile and luxury vinyl plank surfaces. It rolls quietly without a protective mat. Buyers who need wheels for heavy industrial equipment or rough concrete floors should look elsewhere.

Questions about this item

Should I choose the five-wheel pack or buy them individually?

The product is only sold as a five-wheel pack; one set replaces all casters on a standard chair.

What does the 140 lb per wheel rating mean when the chair is in daily use?

Each caster handles 140 lbs of dynamic load, so a full set supports 700 lbs while rolling under normal office conditions.

The stem is listed as 10 mm but the highlights mention 11 mm — which size actually fits my chair?

The spec sheet shows a 10 mm diameter stem; the 11 mm figure in the highlights refers to the 7/16 inch equivalent, so measure your old caster stem before ordering.
