Universal Office Chair Casters

These 3-inch replacement wheels are designed to fit 98% of standard office chairs using a 7/16 x 7/8 stem mount. The set of five casters upgrades worn-out originals with heavy-duty rubber construction. They deliver smooth, quiet rolling across carpet, hardwood, and tile surfaces. Each wheel weighs 800 grams total for the set.

Buyers needing stem-mounted 3-inch wheels

Ideal for anyone replacing broken or noisy casters on compatible office chairs where silent operation and floor protection are priorities. The universal stem size covers the vast majority of brands without adapters. Not suitable for chairs requiring a different stem diameter, plate mounting, or larger wheel diameters. Specifically noted as incompatible with IKEA chairs.

7/16 x 7/8 stem fitment

The single specification that determines compatibility is the stem size of 7/16 inch diameter by 7/8 inch length. Measure your existing caster stems before ordering to confirm they match these dimensions exactly. The 98% fit claim applies only when this stem measurement matches your chair base. No other mounting method is supported by this product.

Questions about this item

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

The wheels use a 7/16 x 7/8 stem mount, which matches the standard size on most office chairs.

Will these 3-inch rubber casters roll smoothly on the same hard floors where my old plastic wheels scratched?

Yes, the premium rubber tread is designed for silent, effortless rolling on all floor types without marking surfaces.

How can I confirm the set of five is installed correctly and performing as intended?

Each wheel should swivel freely, roll quietly across the floor, and show no wobble when the chair is occupied.
