Roller Chain Length Formula

The number of teeth on each sprocket is known.

Roller chain length formula.

Sprocket center distance for a roller chain of known length equation and calculator. Follow our easy to read roller chain size chart for your industrial applications. An even number of pitches is always preferable to an odd number which requires an offset section. Confusion doesn t rule the day when roller chain sizes are detailed in every dimension possible at usa roller chain.

We also have a sprocket diameter calculator that determines a sprockets diameter based on the pitch of the chain and the number of teeth. Chain length in pitches cl 2c a 2 t c note. To keep motorcycle rear wheel within adjustment range. Calculating roller chain length given two sprockets a known distance apart.

If chain length is fractional round off to the nearest whole number of pitches. For our flt h chain drive conversions we supply a 120 link o ring ek chain. Compare diameter width and thickness as you find drive chain sizes that move your machinery in the right direction. If your centre distance is too short a minimum will be calculated.

The chain length is given by number of chain links and the chain pitch. Roller chain length calculator the calculator will determine your required roller chain length and ideal centre distance given the sprocket teeth chain pitch and centre distance. An offset section also called a hunting link section must be used when a chain contains an odd number of links. We use sprocket specialists for many of our sprockets and since we raced bikes at the bol d or in 1977.

The sliding sprocket position is adjusted accordingly. The lower the chain revolutions the more frequently each chain link engages the same sprocket tooth so greater and more uneven the wear.
