Flanged Cast Iron Wheels (FD/FL Class) — Single and Double Flange Wheels That Hold the Track
Updated 2026-11
Flanged cast iron wheels solve the oldest guidance problem in material handling: keeping a cart on a defined path. The flange — a raised rim on one or both tread edges — runs against the side of a rail or track and provides the lateral constraint that a flat-tread wheel cannot, so the load travels the same line every cycle without guide rollers or operator steering. The manufacturer describes the mechanism exactly this way: flanged caster wheels utilize floor tracking to keep casters and carts traveling safely in a continuous, straight line, on a robust high-capacity cast-iron body.
The published chart carries two lines: FD, single-flange cast iron at 500-3,000 lb over 3-14 in diameters, and FL, double-flange at 500-2,000 lb in 5 and 10 in — both with the full cast-iron temperature window of -40 to +800 °F, which is why the class also appears on oven and kiln carriages where track-keeping and heat coincide. The construction offers various bore sizes for plain-bore use, keyway and set screw drive, or a variety of bearings. Our supply path is own production plus outsourcing; standard constructions ship in 15-20 days and custom configurations in 30-40 days.

FD and FL are separate manufacturer lines — each band stays its own row. The flange holds the wheel on the track; it does not add load capacity, and the rating for your diameter, axle and track arrangement is stated on the quotation.
Applications & Selection
How the flange guides — and when V-groove is the comparison
A flanged wheel keeps direction by constraint: the tread carries the vertical load on the rail crown while the flange face takes the lateral loads every time the load drifts. That makes it the simple choice for straight fixed track — oven carriages, kiln cars, material trolleys on rail, transfer cars — and the published -40 to +800 °F window means the constraint survives the heat sections too. The construction data matters for driven duty: various bore sizes for plain bore, keyway and set screw when the wheel drives, or bearings where it idles.
The family comparison is the V-groove wheel, which guides by running in the root of an inverted angle-iron track rather than by flange against rail edge. Published channel taxonomies list the two as sibling track-wheel categories, and the practical split is track furniture: where the facility already has rail, flanged wheels are the natural fit; where angle iron is the guide, V-groove is. Double flange (FL) adds constraint on both sides for track with guidance on both edges; single flange (FD) covers the common one-sided rail with a wider 3-14 in size spread and a higher published ceiling.
Selection points to settle before you RFQ
Start with the track, not the wheel: rail gauge, rail head profile, and whether guidance is one-sided or both. The flange must match the rail — flange height, root clearance and tread diameter together decide whether the wheel rides the crown or chips the flange. State the driven or idle role: a driven wheel needs the keyway-and-set-screw bore option; an idler takes bearings. The published bands — FD 500-3,000 lb, FL 500-2,000 lb — are line references; axle size and track condition decide the real rating.
Then the environment: the cast-iron window of -40 to +800 °F makes this class oven- and freezer-capable, but bearing and lubricant limits sit lower — state the actual temperature at the wheel. Bring load per wheel with your safety divisor, and the duty cycle: a transfer car making thousands of repeats wears the flange face, so flange wear belongs in the inspection plan from day one. Standard constructions ship in 15-20 days, custom bores and flange profiles in 30-40 days, MOQ 200 pieces.
Frequently Asked Questions
Flanged wheels or V-groove wheels — which track system should I build?
They answer different track furniture. A flanged wheel runs on a flat rail head with the flange riding the rail edge — the fit when the facility has rail. A V-groove wheel runs in the root of inverted angle iron, which is cheaper to install and self-cleaning on dirty floors. Published channel taxonomies treat them as sibling track-wheel categories. New build on a budget usually goes V-groove; existing rail, oven and kiln cars, and driven applications usually go flanged.
Single flange or double flange?
The published lines make the trade visible: FD single flange spreads 500-3,000 lb across 3-14 in — the standard answer for one-sided rail where the flange catches one edge; FL double flange carries 500-2,000 lb in 5 and 10 in with constraint on both tread edges, for track that guides on both sides or loads that shift laterally. Doubling the flange does not add capacity — it adds lateral constraint — so choose by track geometry, not load.
What should my flanged wheel RFQ include?
Track drawings or rail section (gauge, head width, flange-way clearance), load per wheel with your safety divisor, driven or idle role (keyway bore vs bearings), diameter and tread width, temperature at the wheel, and quantity. Ask for the per-configuration rating in writing — published line bands position the class; the quotation is the commitment.
Ordering & Documentation
Documents
Every order ships with a packing list and commercial invoice. Dimensional drawings — including flange profile, bore and keyway dimensions — are available on request so the track interface can be checked before production.
Quotation
A quotation needs: track section or drawing, load per wheel, diameter and tread width, driven or idle bore specification, temperature at the wheel, and quantity. The confirmed quotation states the rating for your configuration — the FD/FL bands above are published line references, 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, flange profiles or keyway drives. The usual validation is a trial pass over the full track length, then a flange-face and bore check before the batch order.
Storage & shipping
Cast iron wheels store dry with the bore and flange faces protected from transit chips; bare cast iron surfaces rust superficially in humid storage without affecting service. Before installation, inspect the flange root for cracks and the bore for ovality — both are the surfaces the track system depends on.
