Applications of 20A U-type Cover Chain
20A U-type cover chain is a heavy-duty enclosed conveyor chain compliant with ANSI standards. The U-shaped cover effectively shields the chain body from dust, debris, splashes and external impacts, making it widely used in harsh industrial working conditions.
Food & Beverage Industry
Ideal for food processing, packaging and conveying lines. The protective cover prevents food residues and liquids from entering chain gaps, keeping the chain clean and meeting hygiene requirements.
01
Chemical & Pharmaceutical Industry
Suitable for production lines with dust, chemical splashes and slight corrosion. The cover protects components from chemical contamination and extends service life.
02
Building Materials & Mining
Applied for conveying cement, gravel, sand and other bulk materials. It stops granular materials from jamming chain joints.
03
Automation & General Machinery
Used for assembly lines, pallet conveying and heavy-load logistics systems. It resists mechanical impact and reduces wear.
04
Waste & Recycling Industry
Perfect for waste sorting and recycling conveying lines against messy sundries and dust.
