Abilene Machine’s feederhouse chains and sprockets for combines use quality materials to meet or exceed OEM specifications. Our chains are assembled with high-quality CA550 and CA557 chain to match the original. Some CA557 chains are offered to replace the standard OEM CA550 chains. Our two, three and four-chain feederhouse chains have slats that are mounted directly over the roller pins to prevent stretching. Heavy-duty roller chains feature full side plates for added strength and are available with chrome pins for longer wear. In addition, our slats are available in smooth and serrated and are bolted to the chain with 3/8" Grade 5 hardware with locktite for added durability.
