Scrapers
Drop forged chains as well as double drag link chains may be equipped with plastic and/or steel scrapers. For heavy-duty use, either of these chains may be equipped with welded steel scrapers. Double drag link chains may also be equipped with a bent steel scraper, attached to the outer link.
Chains with plastic scrapers have quite a few advantages. The plastic scrapers are made of wear-resistant nylon and are flexible. The fact that the chain rests on the plastic scrapers eliminates the steel-on-steel contact. Plastic scrapers are temperature resistant between -20 ˚C tot +70 ˚C. The special zytel scraper is temperature resistant up to +110 ˚C. The following table shows the various different types of plastic scrapers, together with the corresponding chain.

- noise-reduced, 60 db(A) measured at a 1 m distance
- low frictional resistance, saving up to 20 % of the energy
- less costly, less wear and tear of the bottom plate and the chain
- flexible, bendable under high pressure
- eliminates the need for guiding and wearing strips
- very quickly and easily assembled or replaced
