Casters That Keep Rolling Near the Heat
park a normal caster near an oven and two things fail: the PU or rubber tread softens and marks off, and the bearing grease cooks out and seizes. a high-temperature caster answers both — a heat-tolerant wheel, phenolic or cast iron, on a heat-rated bearing.
Move a rack in and out of an oven, a proofer, or a smokehouse on ordinary casters and they do not last. a PU or rubber tread softens in the heat, marks off on the floor, and eventually breaks down; worse, the bearing grease cooks out, so the swivel and the wheel stiffen and seize. the wheel that rolls fine at room temperature is the wrong tool a few feet from the heat.
A high-temperature caster is built from materials that hold up. a phenolic wheel is the common choice for bakery and oven racks — it carries good load, rolls with low effort, and handles continuous dry heat in the region of 250°C. for industrial ovens and kilns, a cast-iron or steel wheel goes higher still. both are hard wheels — chosen for heat, not for cushioning — so they are not floor-soft like a PU tread.
The wheel is only half the job: the caster also needs a heat-rated bearing and lubricant, or the grease breaks down even though the wheel survives. builds cover swivel, fixed, and braked, and the exact temperature rating depends on the wheel, the bearing, and whether the heat is continuous — so it is confirmed per model on your quote. the range meets ANSI/ICWM and ISO 22883 requirements.
High-temperature range
Phenolic for bakery and oven racks; cast iron / steel for industrial ovens and kilns.
Phenolic Swivel · Brake
The usual choice for bakery and oven racks — good load, low rolling effort, holds up to continuous dry heat. brake to park the rack.
Phenolic Rigid / Swivel
Phenolic wheel in rigid and swivel builds for oven and proofing racks that move all day near the heat.
Cast-Iron Swivel
Cast-iron wheel for the hottest service — industrial ovens, kilns, and curing lines where phenolic is not enough.
Cast-Iron Rigid
Fixed cast-iron build for straight-line tracking on heavy kiln and oven carts under high heat.
Wheel material & temperature
Pick the wheel for the heat; confirm the exact rating per model on your quote.
| Wheel | Heat (guide) | Best for |
|---|---|---|
| Phenolic | Continuous dry heat ≈ 250°C | Bakery, oven, and proofing racks |
| Cast iron / steel | Higher than phenolic | Industrial ovens, kilns, curing lines |
| Bearing & lube | Heat-rated to suit the wheel | Keeps the swivel and wheel from seizing |
| Exact rating | Depends on build & duty cycle | Confirmed per model on quote |
Where they are used
Oven & proofing racks
Bakery oven racks, proofing trolleys, and smokehouse racks rolled in and out of the heat all day.
Ovens & kilns
Curing ovens, kiln cars, and powder-coat lines where phenolic is not enough and cast iron is needed.
Autoclaves & dryers
Autoclave and dryer carts and other process equipment exposed to sustained high temperature.
Sell it under your own brand
OEM / ODM branding and neutral packaging sized for regional distributors, not mass-OEM tonnage.
Wheel + bearing to spec
tell us the temperature, load, and rack; we match the wheel material and heat-rated bearing and confirm on a 24–48h drawing.
Your mark, or unbranded
we laser-etch or pad-print your logo, or ship unbranded in neutral cartons. the buyer sees your brand.
Distributor-scale
per-model minimums at distributor scale — no mass-OEM tonnage required. custom builds follow the 24–48h drawing path.
Mixed-load stocking & container logistics
Stock range coverage without committing a full container to one model.
| Term | How it works |
|---|---|
| Mixed-load container | Consolidate high-temperature, food-service, and other caster types into one container. |
| Per-model minimum | Held at distributor scale with no mass-OEM constraint, so you carry depth across materials and builds. |
| Lead time | Standard phenolic and cast-iron models from stock; custom builds follow 24–48h drawing, typically about 14–21 days for bulk OEM. |
| Container loading | we plan cartons per container to fill cube and weight efficiently; cast-iron models are dense, so weight fills first. |
| Trade terms | FOB and CIF supported. confirm port, Incoterm, and per-model quantities on your quote. |
