ANSI Roller Chains (40, 50, 60, 80 to 160)
ANSI roller chain is identified by a number: the first digits give the pitch in eighths of an inch, so 40 is 1/2 inch and 80 is 1 inch. It is used on motor, gearbox and machine drives. Match the sprockets to the chain number, strand count and tooth count.
- Pitch from 6.35 mm to 50.8 mm
- Pre-stretched and lubricated chain available
