Stemless CastersFinding a caster to fit the built-in stem on your chairDoes your chair have the caster stems welded or built-in? Now one of the casters has broken and need replaced.
Finding a replacement caster to fit the stem may be difficult. The caster-end of the stem can differ
significantly from one model to the next and from one manufacturer to the next.
First: Try contacting the furniture dealer or the manufacturer to see if they can provide a replacement caster.
Otherwise: Take some accurate measurements of the stem (the portion that would fit into the caster) and enter them into the table below.
Calipers are best to get accurate measurements of each dimension and are available at most hardware stores with the cheapest plastic
models around $5-$10.
Compare your dimenions to those in the table. Follow the link of the stem that is closest to yours to see
what stemless casters have the best chance of fitting your stem.
Installing Your New Stemless Casters
The stemless caster will need to be completely seated on the stem to operate correctly: retained yet swiveling freely.
With the stem built into the chair, the caster must be tapped to seat it onto the stem. This must be done carefully so as not to harm the caster. For a twin-wheel caster place a small board, 3/8" or 1/2" thick,
between the wheels against the base of the caster. Firmly tap the wood, forcing the caster fully onto the stem. For a ball caster, use a rubber mallet or some material to protect the caster.
