    There is formula for calculating the pitch, but it also requires the technical data as written earlier.

    in Rack and pinion
    first u need to know the load,to choose the module type.ie.module1,1.5 etc.higher the module more distance u will travel for one rotation of pinion.and lower the resolution will be.
    you need to have the gears technical handbook to choose the appropriate rack and pinon.give me some time i will post the gear reference manual.using which u can do the module and pitch calculations.

    hi, i would like some information about " how to mount a rack and pinion in the vertical plane".. the pinion will be moving the rack, which will follow a reciprocating vertical motion.. the load is aprroximately 3 kg.. any recommendation on wat type of rack should i use?

    thx beforehand..
