High Load Capacity Cast Iron Casters operable from -20℃ to 300℃ Rust Prevention concrete mixer wheels.
Features of Cast Iron Casters
- High Load Capacity: The dense and robust structure of cast iron allows it to support heavy loads, typically exceeding 500kg.
- Wear and Impact Resistance: With high hardness, it is suitable for frequent movement on rough surfaces and is less likely to deform or be damaged.
- Rust Prevention: Often treated with zinc plating or anti-rust coatings, it is suitable for humid environments such as warehouses and workshops.
- Wide Temperature Range: It has better heat resistance than plastic casters and can operate stably in environments ranging from -20℃ to 300℃.
Wheel Material: Cast iron
