ANSI 35 Roller Chain Idler Sprocket Type C, 5/8 Bore, 20T
✔️ 1x sprocket with bearing 203KRR2, hardened 1045 steel
This Type C roller chain idler for ANSI #35 chain is used for power transmission in agricultural, woodworking, and machine tool setups. It matches 3/8 inch pitch (9.53 mm) and a 5/8 inch bore (15.9 mm) with 20 teeth, delivering stable engagement. The sprocket is made from ANSI 1045 carbon steel and teeth are hardened to HRC 38-42 with high-frequency quenching, while a blackened finish adds corrosion resistance. Interchangeable with Martin, Browning, and other idlers, it's a solid choice for legacy and modern equipment alike.
