DIN763 Standard Link Chain Features:

• Precision manufacturing, accurate size. Strictly follow the DIN763 standard. Taking a 5mm diameter chain as an example, the ring length is 12mm, the ring width is 8mm, and the aspect ratio is 1.8, ensuring perfect meshing with the sprocket. The vibration amplitude during transmission is ≤0.5mm, which is suitable for packaging machines and other equipment with high transmission accuracy requirements. The welding points are laser welded (stainless steel model) or flash butt welded (carbon steel model). The weld is flat (height ≤0.3mm) and burr-free to avoid scratching the contact material.

• Smooth transmission, suitable for precision equipment. The chain ring adopts the "inner flat and outer round" design, and the contact area with the sprocket is 30% larger than that of ordinary chains, and the transmission efficiency is ≥95% (ordinary chains are about 90%). On the packaging machine conveyor line, the 1-ton DIN763 chain drives the conveyor belt to run, and the speed fluctuation is ≤±1%, ensuring the precise positioning of the packaging bag and reducing the material deviation rate by 50% compared with ordinary chains. Suitable for German light-duty hoists (such as JDT series), the verticality deviation during lifting is ≤2°, and the lifting accuracy is ±2mm.

DIN763 Standard Link Chain Typical Applications:

• Food and Packaging Machinery. In the canned food production line, stainless steel DIN763 chains (5mm diameter) are used to transport cans. The smooth surface of laser welding does not leave any food residue, can withstand high-temperature cleaning (80°C hot water), and can run 16 hours a day without rust. The film traction system of the packaging machine uses a 3mm diameter carbon steel chain. The precision transmission ensures stable film tension (error ≤2N), and the packaging qualification rate is increased to 99.5%.

• Medical and Clean Environment. The material conveying equipment in the pharmaceutical workshop uses stainless steel chains (6mm diameter) to transport medicine bottles and packaging materials. The corrosion resistance is suitable for alcohol disinfection environments and there is no metal ion precipitation (in compliance with USP Class VI standards). The laboratory small lifting equipment (0.5 ton class) uses DIN763 chains. The high precision ensures that there is no shaking when the reagent bottle is lifted to avoid liquid spillage.

• Lightweight conveying and lifting. The warehouse automation sorting line uses a 4mm diameter carbon steel chain to pull the sorting trolley (load 1 ton). The pitch is precise (20mm±0.1mm) to ensure that the trolley positioning error is ≤5mm, and 800 packages are processed per hour. Small workshops use 1-ton chain with hand chain hoist to hoist the motor (0.8 tons). The stability is better than ordinary chains, reducing the risk of collision during equipment installation.
