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.

JRT medium-duty casters for toolboxes, dollies and MRO carts

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.

How they’re built

Rolling effort

Dual ball bearings

Precision dual ball bearings cut manual starting and rolling resistance by about 15–20% under load.

Holds in place

Total-lock brake

Locks the wheel and the swivel together so a parked, loaded cart stays put.

Fork & mount

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.

Brand the product

Your mark, or unbranded

we laser-etch or pad-print your logo, or ship unbranded. the buyer sees your brand, not ours.

Neutral & custom packaging

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.

Low entry threshold

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.

Medium-duty & procurement FAQ

What loads and sizes do medium-duty casters cover?
Wheels run 100–125mm with ratings from 80kg to 500kg per caster, so a four-caster cart carries roughly 320kg to 2,000kg depending on the model and a safety margin.
Which tread should I choose?
PU carries the highest loads and rolls easily on hard floors; nylon resists chemicals and rolls light; elastic rubber cushions shocks and runs quietly; odourless rubber suits indoor and display use without scent.
Are braked versions available?
Yes. total-lock brakes hold both the wheel and the swivel so a parked cart or cabinet stays put. plain swivel and bolt-hole builds are also available.
What is the fork finish?
Forks are zinc-plated steel for everyday corrosion resistance in workshop and warehouse use. a stainless-steel option is available for wash-down and damp areas.
Do they roll easily under load?
Precision dual ball bearings lower manual starting and rolling resistance by about 15–20%, which matters most on loaded trolleys pushed all shift.
Can we sell these under our own brand and mix models in one order?
Yes. we laser-etch or pad-print your logo or ship unbranded with neutral cartons, and consolidate medium-duty with other caster types into one mixed-load container, with per-model minimums held at distributor scale.
