Shock crop slugs in combine feederhouses and high-torque variator sheaves rapidly stretch ordinary industrial chains and belts. Our agricultural transmission line features shot-peened alloy steel CA550/CA557/S38 roller chains with pre-bolted serrated chrome slats, aramid (Kevlar®)-corded banded V-belts, and vulcanized fabric-reinforced rubber draper header belts engineered for zero elongation during peak harvest.

We supply both complete ready-to-install 2-strand, 3-strand, and 4-strand feederhouse slat assemblies (bolted with serrated flange locknuts for zero loosening) and bulk CA550 / CA557 / CA620 agricultural roller chains with connecting links.
Combine cylinder drives, straw choppers, and mower conditioners use backside idlers and endure heavy shock clutching. Aramid (Kevlar) cords provide 3x higher tensile strength and near-zero stretch under reverse-bend shock loads.
