⑥ PRODUCT OVERVIEW
────────────────────────────────────────────────────────────────────────────
Introducing the A04-1KU Series — our flagship Super Heavy Duty,
Impact-Resistant, Flat Iron Core Caster built for the most demanding
industrial loads on the planet.
This 10" × 3" (250-10) model carries up to 2,000 kg (4,409 lbs) on a
single wheel — that is a combined 8,000 kg (17,637 lbs) system load
when a standard four-caster configuration is used. The 75mm wide flat
tread distributes weight across a broad contact patch, making it ideal for
extreme point loads, uneven floors and shock-heavy environments.
Every A04-1KU caster is engineered in-house at our factory and supplied in
three mounting styles: Rigid (Fixed), Swivel and Swivel + Brake — so
you can specify the exact steering and locking behaviour your equipment
needs.

⑧ MATERIAL ADVANTAGES
────────────────────────────────────────────────────────────────────────────
▌ A. Iron Core Polypropylene (Pu) Wheel — Shore A 95–98
• Cast PP tread bonded directly to a solid steel iron core — the
material will NOT delaminate under load (unlike bonded rubber).
• Shore A 95–98 is the upper limit of industrial hardness: it resists
cutting, chunking and abrasion from steel shavings, weld spatter and
rough concrete.
• PP is naturally self-lubricating, low-friction and resistant to
most oils, greases, alkalis and many chemicals — a major advantage
over natural rubber in factory environments.
• The flat (zero-crown) tread profile keeps the full 75mm width in
contact with the floor for maximum stability.
• White/light colour makes contamination and wear visually easy to
spot on the shop floor.
▌ B. The 75mm Extra-Wide Tread — What Makes This Size Different
(Standard casters use a 50mm wide wheel. Here is why 75mm matters.)
✓ Larger contact patch = lower floor pressure (PSI).
A 2,000kg load spreads over 75mm of tread instead of 50mm, so the
wheel is far less likely to sink into soft floors, epoxy coatings,
wooden planks or lightweight workshop flooring.
✓ Superior weight distribution on uneven floors.
The wider footprint bridges small gaps, expansion joints, floor
seams and slight surface irregularities without the wheel "dropping"
into every dip — protecting both the load and the operator.
✓ Dramatically improved lateral (side-to-side) stability.
A wide wheel resists tipping and racking forces when a heavily
loaded trolley is pushed off-axis or turned sharply. This is
critical for tall, narrow die carts and mold carriers.
✓ Reduced rolling resistance under extreme load.
The broad tread deforms less under compression, so the wheel rolls
more freely and requires less push force than a narrow wheel carrying
the same 2,000kg.
✓ Better heat dissipation from the iron core.
More tread mass and a larger steel core surface area mean heat
generated by continuous heavy rolling is dissipated faster — the
wheel stays cooler and lasts longer in 24/7 operations.
✓ Increased service life.
The same total load is shared over a larger tread volume, so wear
is distributed and the caster simply lasts longer between changes.
▌ C. Galvanized Steel Bracket (8mm Thick)
• Hot-dip galvanized finish provides a thick, bonded zinc layer that
protects against rust, humidity, cutting fluids and wash-down
environments — far superior to painted brackets, where paint chips
and corrosion starts immediately.
• 5mm thick formed steel plate absorbs shock loads without bending,
cracking or de-welding — essential at 2,000kg per caster.
• Precision robotic welding on every load-bearing joint.
• The 160 × 160mm reinforced top plate with four 16mm bolt holes
distributes mounting stress evenly across the equipment base — no
plate flex, no pull-out.
▌ D. 6205 Precision Ball Bearing
• Large 6205 bearing (25 × 52 × 15mm) sized specifically for heavy
radial and impact loads.
• Sealed construction keeps dust, grit and moisture out while
retaining lubrication — maintenance-free in normal service.
• Runs smooth and quiet even under the full 2,000kg rating.

⑨ APPLICATION GUIDE — Where the 10" × 3" Size Is Used
────────────────────────────────────────────────────────────────────────────
The 10×3 size is the workhorse for EXTRA-HEAVY, SLOW-MOVING loads where
floor protection and stability matter more than tight turning. Typical
uses:
▶ METAL FABRICATION & HEAVY MACHINERY
- Steel plate cutting & welding tables (fabrication shops)
- Steel coil & sheet metal transfer carts (steel service centres)
- Die carts & mold carriers (stamping & die shops)

- Structural steel assembly jigs (bridge & steel works)
▶ DIE & MOLD HANDLING
- Injection mold base trolleys (molding plants)
- Die storage & transport racks (automotive stamping)
- Mold changeover carts (appliance & tooling)
▶ FOUNDRY, FORGING & ROLLING MILL
- Ladle & crucible transfer cars (foundries)
- Ingot & billet handling trolleys (forging plants)
- Rolling mill roll changing carts (steel mills)
▶ POWER GENERATION & ENERGY
- Transformer & switchgear dollies (substations)
- Generator & turbine component carts (power plants)
- Wind-turbine nacelle & blade handling rigs (wind energy sites)

▶ RAIL, AVIATION & DEFENCE
- Aircraft engine & landing-gear dollies (MRO hangars)
- Rail bogie & axle maintenance trolleys (rail depots)
- Missile & ordnance handling carts (defence facilities)
▶ CONSTRUCTION & INFRASTRUCTURE
- Precast concrete formwork trolleys (prefab yards)
- Heavy rebar & beam transport carts (construction sites)
- Bridge girder handling systems (infrastructure projects)
▶ WAREHOUSING & LOGISTICS (heavy end)
- Coil & roll storage shuttles (paper & steel warehouses)

⑩ WHY CHOOSE THE 10" × 3" SIZE (vs. other sizes in the A04-1KU range)
────────────────────────────────────────────────────────────────────────────
• 2,000kg single-wheel capacity — the right choice when the 12×3 (2,500kg)
is more capacity than you need and a more compact wheel is preferred.
• 355mm mounting height — lower centre of gravity than the 12×3 (380mm),
giving better stability for tall loads while still clearing floor debris.
• The 75mm wide tread is shared across the A04-1KU series, so the
stability and floor-protection benefits are consistent — only diameter
and capacity change.
• Ideal balance of load rating, rolling resistance and equipment clearance.

────────────────────────────────────────────────────────────────────────────
⑫ SEO-RICH DESCRIPTION PARAGRAPH (natural long-tail keyword integration)
────────────────────────────────────────────────────────────────────────────
If you are searching for a 10 inch heavy duty caster wheel rated for
2,000kg, the A04-1KU-10×3 super heavy duty iron core polypropylene caster
is engineered for exactly that. With its extra-wide 75mm flat tread, this
impact-resistant wheel distributes extreme loads across a broad contact
patch — making it the preferred choice for steel coil carts, die trolleys,
welding tables, transformer dollies and other super-heavy equipment.
The galvanized bracket resists corrosion in harsh factory, foundry and
outdoor environments, while the 6205 ball bearing ensures smooth rolling
even under full load. Whether you need a fixed caster for straight-line
tracking, a swivel caster for tight manoeuvring, or a swivel brake caster
for locked positioning, the A04-1KU series has you covered.

⑬ FAQ
────────────────────────────────────────────────────────────────────────────
Q1: What is the maximum load per caster?
A: Each 10×3 caster is rated for 2,000kg (4,409 lbs). A standard 4-wheel
set therefore supports approximately 8,000kg — always include a
safety margin and consult us for dynamic (moving) load calculations.
Q2: What is the difference between the 75mm wide wheel and a standard 50mm?
A: The 75mm wide tread provides a much larger contact area, which lowers
floor pressure, improves lateral stability, bridges floor gaps and
reduces rolling resistance under the same 2,000kg load. It is
significantly more stable and floor-friendly than a 50mm wheel.
Q3: Is the bracket galvanized?
A: Yes. The 5mm thick steel bracket and fork are hot-dip galvanized for
maximum corrosion resistance, outperforming painted alternatives.
Q4: Can I get this in rigid, swivel and brake versions?
A: Yes — Model A04-R-1KU-10×3 (Rigid), A04-S-1KU-10×3 (Swivel) and
A04-T-1KU-10×3 (Swivel + Total Brake) are all available from stock.
Q5: Do you offer customization?
A: Absolutely. As a professional caster manufacturer with over 10 years
of factory experience, we welcome OEM/ODM orders — see the Custom
