Office chair wheel set of 5

The Metra 3 Inch Stem Mount wheels replace standard office chair casters with a set of five transparent black polyurethane rollers. Aerospace-grade ABEC7 bearings provide ultra-smooth, low-resistance rolling on hard surfaces. The reinforced top plate and double ball bearing raceway support up to 650 lb total load capacity. Stem size is 7/16" x 7/8" (11 x 22 mm) for common office chair fitment.

Upgrade from standard casters

Most factory wheels use low-grade ABEC3-5 bearings that develop friction and noise over time. The jump to ABEC7 bearings is worth it when daily rolling feels gritty or when floor protection matters on wood, tile, laminate or vinyl. Thick transparent polyurethane prevents core separation and removes the need for a separate chair mat. Not compatible with IKEA chairs; verify stem dimensions before ordering.

Limits of the stem mount interface

The 11 x 22 mm stem fits many but not all office chairs, so measurement is required before purchase. Wheels are 3 inch (75 mm) diameter and are not suitable for high-pile carpets where larger 6 inch (150 mm) casters perform better. Total load capacity reaches 650 lb across the set of five. OVLLAN has manufactured to USA Caster Industry Standards since 1997.

Questions about this item

What stem size does the 3 inch Metra wheel set need to fit my chair?

The stem measures 7/16" x 7/8" (11x22 mm); measure your old casters before ordering.

How do I install these stem-mount casters without damaging the chair base?

Pull the old casters straight out, align the new stems, and press firmly until each seats fully — do not hammer.

When should I replace the ABEC7 bearings in these transparent polyurethane wheels?

Replace the full caster if rolling becomes rough or noisy; the sealed ABEC7 bearings are not serviceable.
