Toothed and pocket wheels go along with chain ends DIN 764 and CICSA chains LH. CICSA manufactures them in one piece or two halves (assembled with transversal screws) for an easier disassembling.
Toothed and pocket wheels for scrapers and conveyors are made of GS-800 spheroidal graphite cast iron or special case hardened alloy steel, while toothed and pocket wheels for traction conveyors and other applications are made of quenched alloy.
