Universal Stem Mount Compatibility

These Metra casters fit most office chairs using a standard 7/16 inch (11mm) stem diameter and 7/8 inch (22mm) stem length. The press-in design allows tool-free installation in under five minutes by pulling old wheels straight out and pressing new ones until they click. They are not compatible with IKEA chairs or threaded stem models, so verify your existing caster stem before ordering.

Heavy Duty Build and Floor Protection

Each wheel supports 130 lbs dynamic load for a total set capacity of 650 lbs, using an iron bracket with electrophoretic black coating for rust resistance. Precision dual ball bearings and a polyurethane outer layer provide smooth, quiet rolling on hardwood, tile, laminate and low-pile carpet without scratches or marks. The soft PU material absorbs impact to protect floors without requiring a separate mat.

Upgrade From Failed Stock Casters

This five-pack replaces worn or noisy original casters that scratch floors and disturb quiet environments. The jump is worth it when your current wheels leave marks, generate rolling noise or fail under daily load. Buyers needing threaded stems, IKEA-specific fitment or a different wheel diameter should look elsewhere.

Questions about this item

What is the stem diameter and length that the Metra wheels use for mounting?

The wheels use a 11 mm stem diameter and 22 mm stem length for press-in style chair bases.

What are the physical dimensions and weight of the Metra wheel set?

Each wheel has a 10 mm diameter and 10 mm width; the five-piece set weighs 1.215 kg.

How do you install the Metra wheels and what is the common mistake?

Pull old casters straight out with steady pressure, then align the new stem and press down until it clicks; the mistake is twisting or angling the stem instead of pressing straight in.
