Heavy-duty Red Plastic Core Pp Caster 6 Inch Lightweight Rust-free Pp Trolley Whee Cnc Router Carts And Machining Centers

The 6 Inch (150mm) Heavy Duty Korean Style Red Plastic-Core PP Caster is the heavy-duty champion of the PP series. Featuring a red PP-on-PP dual-color injection molded wheel (Shore 95-98, D scale) on a plastic core, this caster delivers 300kg 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 , Swivel, and Brake  configurations.

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 means lower rolling resistance and easier pushing, especially for female operators and elderly users.
4. Rust-Free — For Humid & Wet Areas: The 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 300kg 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.

The 6 inch size is the heavyweight of the PP series. Its 300kg capacity and 190mm installation height make it the first choice for heavy industrial equipment on flat factory floors.
