Product Introduction
Our Aluminum Profile Casters are the ultimate solution for facilitating seamless movement of machinery and factory equipment. Engineered with precision, these casters are designed to be integrated with aluminum profiles, providing a robust and reliable mobility system. Whether you need to reposition heavy - duty industrial machinery or simply move a lightweight display stand, our casters have got you covered. With a wide range of options available, including casters with and without brakes, swivel and directional casters, as well as plate casters and screw casters, we offer a versatile selection to meet diverse application requirements.

Product Parameters
Material: CS, PU wheel
Color: Black

Product Features
High - Quality Construction: Our casters are crafted from top - grade materials. The wheel components are often made of durable polyurethane, rubber, or nylon, ensuring excellent traction, shock absorption, and resistance to wear and tear. The caster frames are constructed from sturdy aluminum alloy, which not only provides lightweight yet strong support but also offers good corrosion resistance. This combination of materials results in casters that can withstand the rigors of daily use in various industrial and commercial environments.
Diverse Functionality:
1)Braking Systems: The casters with brakes are equipped with a reliable braking mechanism. This allows for easy immobilization of the equipment when needed, ensuring safety and stability. Whether it's preventing a heavy machine from rolling on an inclined surface or keeping a workstation in place during operation, the brakes provide peace of mind.
2)Swivel and Directional Options: Swivel casters offer 360 - degree rotation, enabling smooth and flexible movement in any direction. This is particularly useful for maneuvering around tight corners or in congested spaces. On the other hand, directional casters are designed to move in a straight line, providing stability and control for applications where linear movement is required, such as along conveyor systems.
3)Mounting Variations: Plate casters feature a flat plate for easy mounting to the bottom of equipment using screws or bolts. This is a common choice for larger and heavier items. Screw casters, on the other hand, have a threaded shaft that can be directly screwed into pre - drilled holes in the aluminum profile or equipment base. This type of mounting is more compact and is often used for smaller - scale applications.

Product Applications
Industrial Manufacturing: In factories, our aluminum profile casters are used to move heavy machinery, such as lathes, milling machines, and robotic arms. The swivel casters allow for easy positioning of these machines during installation, maintenance, and reconfiguration of production lines. Plate casters are commonly used for large - scale equipment due to their ability to distribute the load evenly.
Warehousing and Logistics: In warehouses, casters are essential for moving pallets, storage racks, and trolleys. Directional casters are often used on conveyor - based systems to ensure smooth and controlled movement of goods. Casters with brakes are crucial for securing loaded trolleys and preventing accidental movement in busy warehouse environments.
Office and Retail: In office settings, our casters can be used to make desks, filing cabinets, and display stands mobile. This allows for easy rearrangement of office furniture as the workspace needs change. In retail stores, swivel casters on display racks enable store owners to quickly reposition product displays to attract customers and optimize floor space.
