Maxim Glass-Filled Nylon Wheels (NG Class) — The Highest-Load Polymer Wheel for Cold and Chemical Duty
Updated 2026-11
Maxim-class glass-filled nylon wheels are the high-load end of the plastic wheel world. The construction is nylon reinforced with glass fiber — the manufacturer describes an advanced nylon-and-fiberglass wheel built for ergonomics: it starts rolling easily, keeps rolling, and swivels with ease, while the composite stands up to solvents, extreme temperatures and high loads without absorbing moisture. The published line band runs 700-1,500 lb across 3.25-10 in diameters with a -40 to +250 °F window and the best chemical resistance grade on the wheel-selection chart.
Second-publisher class references frame the same material from the duty side: glass-filled nylon is the highest-load polymer and the first choice for freezer and cryogenic service, typically about 33% glass fiber, holding its impact strength at -65 °F and its load band at both temperature extremes. The honest trade is the floor: nylon is rigid with no compression layer, so it point-loads and marks epoxy and painted concrete. This is a wheel for industrial floors, cold rooms and chemical exposure — not for finished retail surfaces. Our supply path is own production plus outsourcing; standard constructions ship in 15-20 days, custom bores in 30-40 days.

| Class behavior (industry reference) | Highest-load polymer; ~33% glass fiber; retains impact strength at -65 °F; load band held at both temperature extremes; first choice for freezer/cryogenic service |
| Floor trade-off (industry reference) | Poor floor protection — point-loads and marks epoxy/painted concrete; industrial floors only |

The NG band is a published manufacturer line reference; the class behavior figures are second-publisher material references. Neither is a tenant family promise — the rating for your diameter, load and duty is stated on the quotation.
Applications & Selection
Why glass-filled nylon owns the cold chain and the chemical aisle
Every polymer softens or embrittles somewhere; glass-filled nylon pushes both walls out. The glass fiber raises the load ceiling above every other polymer tread — second-publisher class data puts glass-filled nylon at 800-2,500 lb per wheel at 5 in, the top of the polymer range — and keeps impact strength at -65 °F, which is why published material guidance names it the first choice for freezer and cryogenic service: the load band holds at both temperature extremes instead of collapsing on the cold wall the way rubber and PU do.
The chemistry wall moves out too. The manufacturer describes the composite as standing up to solvents and extreme temperatures without absorbing moisture — the combination that ruins nylon-free elastomers in washdown, chemical handling and food-brine environments. Published floor-protection rankings complete the picture honestly: nylon grades poor, point-loading and marking epoxy within weeks. The class decision tree is therefore short — unfinished concrete or industrial floor, cold or chemical duty, high polymer load: glass-filled nylon. Finished floors or noise-sensitive areas: it is the wrong wheel, whatever the load.
Selection points to settle before you RFQ
Size against the line band, not the class spread: the published NG line carries 700-1,500 lb over 3.25-10 in — the 2,500 lb class ceiling belongs to other publishers' per-wheel figures at specific sizes and is never merged into the line. Bring your load per wheel with the divide-by-three safety practice, the floor type in writing, and the temperature envelope at the wheel — both ends, because the class sells on holding rating at the extremes.
Declares the environment: washdown cycles, chemical contact, steam. The manufacturer claims no moisture absorption, but bearings and lubricants do not share it — sealed or stainless bearing options belong in the RFQ when the floor is wet. If washdown cleanliness is the driver rather than load, the white nylon variant (NW line, 600-1,100 lb at 5-8 in) is the economical adjacent line, and our white nylon page covers it. Standard constructions ship in 15-20 days, custom bores and bearings in 30-40 days, MOQ 200 pieces.
Frequently Asked Questions
Glass-filled nylon or cast iron for a 1,000 lb cold-room cart?
Both carry it; they differ in floor and corrosion behavior. Glass-filled nylon rolls with less effort, will not rust in wet or brine-washed rooms, and protects concrete better than metal; published freezer guidance names it the first-choice polymer for cryogenic service. Cast iron carries more at large diameters and shrugs off impact and edge-loading. On bare or industrial cold-room floors with washdown cycles, nylon is usually the right call; on impact-heavy dock duty, metal.
Will glass-filled nylon damage my floors?
On finished floors, yes — published rankings grade nylon poor for floor protection: it is rigid with no compression layer, so it point-loads and marks epoxy and painted concrete quickly. On unfinished concrete, industrial-grade floors and freezer rooms (typically bare concrete) it is acceptable and widely used. If your route crosses finished areas, the wheel to compare is polyurethane or rubber, not a harder nylon.
What should my glass-filled nylon RFQ include?
Load per wheel with your safety divisor, diameter and width, bore and bearing type (sealed bearings for wet rooms), temperature at both extremes, chemical exposure list, floor type in writing, and duty cycle. Ask for the per-configuration rating and the compound basis (glass percentage class) on the quotation — published line bands position the category; the quotation is the commitment.
Ordering & Documentation
Documents
Every order ships with a packing list and commercial invoice. Dimensional drawings (diameter, width, bore, hub length) are available on request, and bearing options are quoted against your wet-room or chemical specification rather than assumed.
Quotation
A quotation needs: load per wheel, diameter and width, bore and bearings, floor type, temperature extremes, chemical exposure, and quantity. The confirmed quotation states the rating for your configuration — the NG line band above is a published reference, not the commitment.
Sample & supply
Standard constructions are produced to order with an MOQ of 200 pieces; smaller trial quantities of catalog items can ship in some sizes — ask with your RFQ. Lead time is 15-20 days standard, 30-40 days for custom bores or bearings. For cold-room duty the usual validation is a trial set through a full defrost cycle, then a bore and raceway inspection.
Storage & shipping
Glass-filled nylon stores without elastomer aging concerns: dry cartons, off the floor, bearings protected. Before installation, check the bore for transit chips and confirm bearing fit — nylon bore tolerances are the dimension that decides how the wheel runs, and a damaged bore cannot be dressed like a metal hub.
