DID 428HD: G&G



As the successor to the tried and tested 428H, new technology was used to make the rollers on the 428HD. Previously, the rolls were rolled from strips of sheet metal, which created a seam and therefore a weak point. With the help of new technology, the rolls are made of round material, thus avoiding a seam.

Compared to the standard 428D chain, the 428HD is reinforced with thicker plates and therefore has significantly higher tensile strength.



- 20-50% more wear resistance compared to DID 428H

- reinforced construction
