Replacement casters for Alera chairs

These dual-wheel hooded casters use a B-stem fitting and are sold as a set of five. They are designed as direct replacements for most Alera seating. Each wheel carries a 100 lb load rating. The black finish matches standard office aesthetics.

Suitable for worn or broken originals

Buyers restoring mobility to compatible Alera chairs will find the correct stem type and wheel profile here. Anyone whose chair uses a different stem size, thread pattern or mounting plate should look elsewhere. The set quantity is fixed at five and cannot be split.

100 lb per wheel load rating

This single figure determines whether the casters can support the intended seat and occupant safely. Exceeding the rating risks premature wear or sudden failure. Confirm the combined weight stays within the limit before fitting.

Questions about this item

My chair uses a B-stem socket — will these 2-inch hooded casters fit directly?

Yes, the B-stem design matches the standard B-stem socket found on most Alera seating, so they press in without adapters.

I’m keeping my existing Alera chair base — do these dual-wheel casters roll smoothly on the same floor surface?

The dual-wheel hooded design distributes load across two wheels per caster, reducing point pressure and letting the chair glide on carpet or hard floor just like the originals.

After I press all five casters into the base, how can I confirm each one is seated and rolling correctly?

Sit in the chair and rock gently; each caster should swivel freely and track straight without binding or popping out of the stem socket.
