TPR Casters

These TPR casters use thermoplastic rubber treads for quiet roll and floor protection on carts and dollies. Casters in this collection range from about 75 to 700 lb per caster. Soft TPR is a strong pick when the floor has chips or grit, similar to soft polyurethane on aluminum (~85 Shore A). Dolly titles rated 1,000 to 1,300 lb are whole-dolly ratings, not per-caster. Set-of-four packs at 2,800 lb are 700 lb per caster. Common uses include food service, schools, hospitals, laboratories, and material handling carts. Mount with a top plate or stem to match your frame. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you place your order today. Keep the load on the rating for that SKU and do not exceed it in service. Capacities below are per caster unless a listing says set. Soft poly aisle: polyurethane casters. Drywall cart builds: drywall cart casters.

What TPR is

Thermoplastic rubber is a molded rubber-like plastic. On these casters it is gray and bonded to a polyolefin core. Where hardness is listed it is about 70 to 75 Shore A, so it cushions bumps and stays quiet compared with nylon or iron [S1].

TPR caster questions

Are TPR wheels non-marking?

Yes. The gray thermoplastic rubber tread on these listings is sold as non-marking for finished floors.

How much weight can a single TPR caster hold?

On this page, about 75 lb on small stem casters up to about 700 lb on 8 x 2 in drywall-cart casters. Ignore dolly pack totals when sizing a single corner.

TPR or polyurethane?

TPR for quiet grip on institutional floors at moderate loads. Polyurethane when you need higher capacity or better cut resistance at the same size.

What mounts are listed?

Top plates (including 4 x 4-1/2 and smaller institutional plates), threaded stems, and grip ring stems, plus some sets and oak dollies.
