4. PRODUCT OVERVIEW

The 5 Inch (125mm) Heavy Duty Korean Style Red Plastic-Core PP Caster is the mid-range workhorse for buyers who want more capacity without moving up to the 6 inch. Featuring a red PP-on-PP dual-color injection molded wheel (Shore 95-98, D scale) on a plastic core, this caster delivers 250kg per wheel with zero rust risk.

The all-plastic construction is completely rust-free, making it ideal for humid, wet, or corrosive environments. The 50mm flat/plain tread provides stable ground contact, while the 5.5mm galvanized Korean-style bracket ensures long service life.

Available in Fixed (Rigid / 定向), Swivel (万向), and Brake (刹车) configurations.

6. FEATURES OF THE RED PLASTIC-CORE WHEEL

--------------------------------------------------

1. RED PP-ON-PP DUAL-COLOR INJECTION
The wheel uses PP-on-PP dual-color injection molding — a red PP tread layer over a black PP core. This gives a premium two-tone look while keeping the wheel 100% plastic, lightweight, and rust-free.

2. SHORE 95-98 (D SCALE) — HARD & DURABLE
PP hardness of Shore 95-98 on the D scale means the wheel resists deformation under heavy static loads. It will not go flat like rubber, and it outlasts soft TPR in high-abrasion environments.

3. LIGHTWEIGHT — EASIER TO PUSH
No iron core means significantly less wheel weight. A lighter wheel = lower rolling resistance = easier to push, especially for female operators and elderly users.

4. RUST-FREE — FOR HUMID & WET AREAS
All-plastic wheel will never rust. Safe for outdoor use, wash-down areas, food processing, and marine/offshore environments where iron-core wheels would corrode.

5. BUDGET-FRIENDLY — CHEAP & PRACTICAL
PP is the most cost-effective caster wheel material. You get 250kg capacity at a fraction of the cost of PU or nylon. Perfect for price-sensitive projects and large volume orders.

6. NON-MARKING & CHEMICAL RESISTANT
PP tread will not leave black marks on epoxy or concrete floors. Resists most acids, alkalis, oils, and cleaning chemicals.

--------------------------------------------------

7. WHERE THIS 5" HEAVY-DUTY KOREAN-STYLE WHEEL FITS

--------------------------------------------------

The 5 inch size is the most popular mid-range option. Its 250kg capacity and 165mm installation height make it the go-to choice for medium-duty industrial equipment.

BEST FOR:

• Flow racks and WIP stations
• Packing and sorting stations
• Medium warehouse dollies
• Assembly line equipment bases
• Maintenance platforms
• Logistics trolleys

NOT FOR:

• CNC router tables (needs spring suspension)
• Scissor lifts (needs spring suspension)
• Uneven outdoor terrain (no shock absorption)

--------------------------------------------------

8. FEATURES & ADVANTAGES OF PP-ON-PP

--------------------------------------------------

• COST-EFFECTIVE: Lowest price per caster among all wheel materials
• LIGHTWEIGHT: No iron core = easy to push, reduces operator fatigue
• RUST-FREE: All-plastic, never corrodes — ideal for wet/humid environments
• HARD & WEAR-RESISTANT: Shore 95-98, outlasts TPR and rubber
• NON-MARKING: Will not blacken epoxy or concrete floors
• CHEMICAL RESISTANT: Withstands oils, acids, alkalis, cleaning agents
• STABLE HEIGHT: No spring = equipment stays at a fixed working height
• 3-IN-1 OPTIONS: Fixed / Swivel / Brake from one model series

13. FAQ

--------------------------------------------------

Q1: What is a 5 inch red plastic-core PP caster?

Q2: Is the 5 inch PP caster suitable for a flow rack?
A2: Yes. With 250kg capacity, it is ideal for flow racks, WIP stations, and packing stations in warehouses and factories.

Q3: Fixed vs Swivel vs Brake — which should I choose?
