Wheels & Parts

Wheels and Parts holds the Carrymaster replacement wheels and the M12/M16 stem adapter. A replacement wheel renews a worn wheel on a Carrymaster leveling or non-leveling caster without replacing the whole caster, as long as the caster model is listed on the wheel's product page.

The wheels come in three materials: PA6 in 4 sizes, MC nylon in 5 sizes and anti-static polyurethane in 4 sizes, from 1.65 to 3.62 inches. Each also fits select models from other caster brands, listed on its product page.

The M12/M16 stem adapter

The Carrymaster M12/M16 Adaptor Stem connects a stem caster to equipment built for the other thread size. It has an M12-1.75x20 thread on one end and an M16-2.00x50 thread on the other.

People Also Ask: 10 questions about caster wheels and parts

Q. Can I replace just the wheel on a Carrymaster caster?

A. Yes, on the models listed in the fit table: the AC, ACP, ACT and APLC leveling casters named there and the ACTM-400 non-leveling caster. Choose the wheel size listed for your model, in PA6, MC nylon or anti-static polyurethane.
If your model is not listed, call us before you order rather than matching a wheel by diameter alone.

Q. Should I replace the wheel or the whole caster?

A. Replace the wheel when the wheel is the only worn part: a flat-spotted, cracked or chunked tread on a caster whose frame, swivel and mount are still sound.
Replace the whole caster when the swivel wobbles or binds, the frame is bent, or a leveling foot or brake no longer works, because a new wheel will not fix those. Our guide on caster wheel load capacity helps if the old caster failed under load.

Q. Can I switch my caster to a different wheel material?

A. Yes, on the listed models. From 1.65 to 2.83 inches, the PA6, MC nylon and anti-static polyurethane wheels are listed for the same caster models, so you can move a caster from the standard PA6 wheel to MC nylon or anti-static polyurethane in the same size.
At 3.62 inches, for the AC-1800F, only MC nylon is offered, the same material the caster comes with.

Q. Does a different wheel material change the caster's load rating?

A. The load ratings on our product pages are for the complete casters as listed, and the wheel product pages do not give a separate rating for the loose wheel.
If the caster runs close to its rating and you plan to fit a different wheel material, call us first so we can confirm it for your model.

Q. Do Carrymaster replacement wheels fit casters from other brands?

A. Some do. Each wheel product page lists select models from other caster brands, by wheel size, alongside the Carrymaster models.
Check your caster's brand and model number against that list before you order. If your model is not on it, call us with the wheel diameter and the caster model.

Q. How do I read a Carrymaster wheel part number?

A. The letters give the material and the digits give the diameter in hundredths of an inch. WHPA is PA6, WHMC is MC nylon and WHPU is anti-static polyurethane, so WHMC00283 is a 2.83 inch MC nylon wheel.
Select the part number by size on the wheel's product page.

Q. Is the anti-static polyurethane wheel ESD rated?

A. Its product page does not list an electrical resistance value or an ESD rating, so do not treat the name as a specification.
If your equipment has a static-control requirement, call us at (973) 777-4922 with the requirement before you order.

Q. Are there replacement wheels for the other non-leveling series?

A. The ACTM-400 is the only non-leveling caster listed on the wheel product pages. For the ACSU, ACLU, ACLMU, ACLHU, ACMM, ACMU and ACM series, no loose wheel is listed.
For those series, replace the whole caster from our non-leveling casters range, or call us to check your model.

Q. How can I tell whether my caster has an M12 or an M16 stem?

A. The number is the thread diameter in millimeters: an M12 stem is 12 mm across the thread and an M16 stem 16 mm. Measure across the outside of the thread, or check the dimension drawing on the caster's product page.
In the Carrymaster AC range, the AC-300S and AC-600S use M12 and the AC-1000S and AC-1300S use M16.

Q. Are there replacement wheels for medical plastic casters?

A. No loose wheels are listed for the Carrymaster medical plastic casters. Those models are sold as complete casters.
To renew one, replace the caster from our medical plastic casters range, matching the mount and size of the old one.
