The U-shaped scraper is a core accessory for conveyor chains such as circular link chains and roller chains, primarily made of polyethylene, nylon, ultra-high molecular weight materials, and polyurethane.

The U-shaped scraper features a low surface friction coefficient, preventing material adhesion and enabling residue-free pushing. This reduces downtime for cleaning, while its self-lubricating properties minimize operational resistance, saving energy and reducing noise. It is well-suited for conveying moist or sticky materials.

The U-shaped scraper weighs only 1/7 to 1/8 of the metal scraper, reducing equipment load and energy consumption. It eliminates spark risks, making it suitable for flammable and explosive environments. It can be bolted onto chains or conveyor belts, with customizable dimensions based on conveyor width and material characteristics. Lightweight and easy to install/remove, it is ideal for routine conveying with medium to light loads, while offering low replacement costs in case of damage

Polyethylene U-shaped scrapers are suitable for conveying grain/light industrial bulk materials under normal temperature and light loads without strong abrasives. Nylon U-shaped scrapers are designed for medium loads, moderate speeds, and materials with slight abrasiveness and mild temperature resistance requirements, such as feed/powder. Ultra-high molecular weight polyethylene U-shaped scrapers excel in heavy-duty applications involving high abrasion, hard particles, low temperatures, and sticky materials, such as mining/bulk cargo. Polyurethane U-shaped scrapers are ideal for sealed leak-proof, shock-absorbing, and oil-resistant conveying of oils/semi-solid/wet materials.
