Medium-Duty Casters That Roll Loaded & Stay Put When Parked
toolboxes, dollies, and commercial cabinets get pushed all shift and parked under load. these run on zinc-plated steel forks with PU, nylon, and rubber treads — 80–500kg each, with total-lock brakes that hold.
A medium-duty cart is judged on two moments: the shove to get it moving when fully loaded, and whether it stays put once parked. our medium-duty casters address both — precision dual ball bearings drop manual starting and rolling effort by 15–20%, and total-lock brakes hold both the wheel and the swivel so a loaded cabinet does not drift.
Tread is chosen for the floor and the job. PU carries the heaviest loads and rolls easily on concrete; nylon resists chemicals and rolls light; elastic rubber cushions shocks and runs quietly over thresholds and joints; odourless rubber suits indoor and display use. sizes run 100–125 mm with ratings from 80 kg to 500 kg per caster.
Forks are zinc-plated steel for everyday corrosion resistance, with a stainless option for wash-down areas. mounting is a top plate for bolt-on frames or a bolt-hole (central hole) for tube and pedestal legs. the range meets ANSI/ICWM and ISO 22883 requirements — one tidy tread-and-mount matrix for a distributor to stock for MRO, workshop, and logistics buyers.

Tread & mount selection
Match the tread to the floor and load, the mount to the frame.
| Tread | Strength | Best for | Loads (per caster) |
|---|---|---|---|
| PU | Highest load, easy rolling | Heavy carts & machine bases | up to 500 kg |
| Nylon | Chemical-resistant, light roll | Hard floors, wet/clean areas | around 200 kg |
| Elastic rubber | Shock-absorbing, quiet | Thresholds, joints, logistics | 130–300 kg |
| Odourless rubber | Scent-free, quiet | Indoor & display carts | around 80 kg |
How they’re built
Dual ball bearings
Precision dual ball bearings cut manual starting and rolling resistance by about 15–20% under load.
Total-lock brake
Locks the wheel and the swivel together so a parked, loaded cart stays put.
Zinc-plated steel
Zinc-plated forks resist everyday corrosion; top-plate or bolt-hole mounting, with a stainless wash-down option.
Sell it under your own brand
OEM / ODM branding and neutral packaging sized for regional distributors, not mass-OEM tonnage.
Your mark, or unbranded
we laser-etch or pad-print your logo, or ship unbranded. the buyer sees your brand, not ours.
Plain cartons or your artwork
packaging defaults to neutral cartons with no JRT marks; we also print boxes to your artwork, barcode, and SKU labels.
Distributor-scale
branding and neutral-pack run at distributor quantities. a bespoke profile follows the 24–48h drawing path with about 12-day mould engineering.
Mixed-load stocking & container logistics
Stock range coverage without committing a full container to one model.
| Term | How it works |
|---|---|
| Mixed-load container | Consolidate medium-duty, light-duty, and other caster types into one container. |
| Per-model minimum | Held at distributor scale with no mass-OEM constraint, so you carry depth across treads and mounts. |
| Container loading | we plan cartons per container to fill cube and weight efficiently. |
| Lead time | Standard models from stock; custom treads, colours, or branding follow 24–48h drawing and roughly 12-day mould work, typically about 14–21 days for bulk OEM. |
| Trade terms | FOB and CIF supported. confirm port, Incoterm, and per-model quantities on your quote. |
