Production differences:
| Chain-type | chain-width (mm) | number of links | production type |
| Zpw 50/280/140 | 280 | 140 | cast links |
| Zpw 5001/280/140 | 280 | 140 | pressed links |
The pressed links are drilled for weight. Connection with pins. Each pin with lubricated needle bearings. From February 1944 onward the rubber-pats are replaced by steel caps. That doesn't change anything in the field but limits the speed on the road to 30 km/h. In June of 1944 this step is reversed because of the many steel caps that are lost.
