2.Sprocket must have strong wear resistance.
3.Sprocket structure must be robust with high shock resistance.

Pitch of Circle Diameter (P.C.D.)

Pitch of Circle Diameter (P.C.D.) can be gained by multiplying coefficient as following format.

Pitch of Circle Diameter (P.C.D.) is calculated by this formula.


Hub Diameter and Hub Width

Diameter and height, of standard sprocket are set as Dimensional specification. However, depending on environment made to order may be required, and the following format will help designing boss diameter and height.
