4 inch high temperature phenolic caster.
A 100 mm phenolic wheel caster for bakery racks, curing trolleys and heat-process equipment — sold with a test protocol instead of a headline temperature, because the assembled caster is what gets tested.
Phenolic is the wheel material heat processes settled on generations ago: a thermoset resin that keeps its integrity where elastomers soften, and rolls on hot floors without picking up the damage that ends rubber and polyurethane wheels. This model puts that wheel in a fork and bearing arrangement specified for heat duty — including the component buyers forget, the grease, which is selected for the temperature pattern (continuous, cycling or radiant) your process actually runs.
Consistent with the whole high temperature line, this page states no maximum temperature. The rating for your configuration is established by bake-testing the production sample under load and is stated on the quotation with its test conditions. A supplier who prints a temperature copied from a resin datasheet is selling you the resin's test, not the caster's.
Specification
| Wheel diameter | 4 in (100 mm) |
|---|---|
| Wheel width | 2 in (50 mm) |
| Wheel | Phenolic resin — thermoset, heat-process standard |
| Temperature rating | Established by sample bake test under load; stated on the quotation with test conditions (no unverified headline figure is published) |
| Configuration | Swivel (rigid companions available) |
| Load capacity | 200 kg per caster at ambient temperature; the rating at your process temperature is confirmed on the quotation from the sample bake test — heat derates every material, and the rating follows the test |
| Overall height | 144 mm |
| Bearing & grease | Specified for the heat exposure pattern stated in your RFQ |
| Mounting | Top plate 114 x 100 mm — bolt hole pattern 85 x 72 mm, hole diameter 11 mm |
| MOQ | Confirmed per order in the written quotation |
| Lead time | Confirmed per order in the written quotation |
Values marked as a class or target are the specification this model is quoted and sampled against. Final confirmed values are stated on the written quotation and verified on the production sample before bulk production.
Configuration options
- Rigid companions for rack layouts (two swivel, two rigid).
- Stainless fork pairing for heat-plus-washdown plants — see the stainless line.
- Exposure-pattern-specific bearing and grease specifications.
What the sample verifies
Before bulk production, the production sample of this model is checked against the locked specification: wheel diameter and — critically — wheel width measured, tread hardness verified, bearing type confirmed, fork and plate thickness measured, and load performance tested per the stated convention (EN 12532 / ANSI ICWM). The approved sample becomes the reference for the shipment, and the order carries batch traceability back to it.

About this model
Why won't you just state a temperature?
Because the honest number belongs to the assembled caster — wheel, bearing, grease and fork — tested as a unit under load. We run that test on the production sample and put the result, with its conditions, on the quotation. See the line page for the full reasoning.
Bakery rack duty: cycling in and out of ovens — suitable?
Cycling is one of the exposure patterns this line is specified against; state the cycle (temperature, time in heat, loads) in the RFQ so the bearing, grease and rating test match it.
Does phenolic mark floors?
Phenolic is a hard wheel: it can mark soft floors and is noisy compared with elastomers. In heat areas floors are specified accordingly; for mixed heat-and-finished-floor duty, talk to us before ordering.
Need this caster under your own brand?
Private label, custom packaging and carton marks are available across the range — mention it in the RFQ and the quotation will include the branding steps.
