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.

Questions about this item

How much weight can these 10 mm wheels support before they become the limiting factor?

Each wheel is rated for 650 lbs, so the set of five handles up to 295 kg total load without bending or losing bearing balls.

Will the wheels stay quiet and cool after rolling all day on carpet and hard floors?

The 360-degree rotation with larger precision balls and a non-oil-leak mechanism keeps rolling silent and prevents heat build-up during continuous use.

What stem size must my chair already have for these Gamma wheels to fit?

Your chair needs a 7/16" x 7/8" stem socket; the wheels push straight in and are not compatible with Ikea chairs.
