Metra Wheels, Pack of 5, 10 mm, Black

Office chair caster set

The Metra wheels arrive as a pack of five 10 mm casters designed to replace worn originals on standard office chairs. Stem-mount fitment with a 7/16 x 7/8 inch stem suits most rolling chairs except Ikea models. The set supports up to 650 lbs or 295 kg combined load.

Fitment and floor impact

Each caster uses a stem mount that pushes into the existing socket without tools, freeing the chair from stuck or noisy original wheels. The 360-degree rotation and larger precision bearing balls allow smooth travel across hard floors and low-pile carpet while preventing surface scratches. The non-bendable shaft keeps alignment steady under load.

Bundled hardware advantage

Five identical wheels are included so the whole chair can be refreshed in one step, eliminating mixed-age casters that cause uneven roll. The black finish with transparent accents matches common chair bases. No additional brackets, lubricants or software are supplied; the improvement comes from the 2X tougher fork, 12% thicker construction and stronger collar that retains bearing balls.
