Iċ-ċomb tal-kamin tal-ballun jissejjaħ ukoll iż-żift, jiġifieri d-distanza tal-moviment lineari tal-kamin taż-żift għal kull rivoluzzjoni. Firxiet taċ-ċomb komuni huma 1, 2, 4, 6, 8, 10, 16, 20, 25, 32, 40. Prodotti żgħar u medji fuq il-post taċ-ċomb ġeneralment għandhom biss 5 u 10, u prodotti taċ-ċomb kbar huma 1616, 2020, 2525, 3232, 4040 (l-ewwel żewġ ċifri huma d-dijametru, u l-aħħar tnejn huma ċ-ċomb).

Meta l-veloċità tad-dħul tkun kostanti, iktar ma jkun kbir iċ-ċomb, iktar ikun mgħaġġel il-veloċità. Suġġeriment Lanbing: Ipprova agħżel 5 u 10 twassal.
The selected lead is related to the required movement speed and system, usually from 4, 5, 6, 8, 10, 12, 20. The size is larger, the lead can also be larger (mainly consider the bearing tooth thickness). When meeting the speed requirements, generally choose a smaller lead (conducive to improving the control accuracy); for high-speed occasions, the lead can be greater than 20; for the ground screw, the lead can be approximately equal to the nominal diameter (under grinding The limit of the helix angle), such as 32 (3232), 40 (4040), of course, it can be larger (non-grinding, but rarely considered). Under the same conditions, the larger the lead, the larger the rotating part, the larger the period error, and the faster the speed. Therefore, flexibility is required at high speeds, and abandoning part of the accuracy requirements will make the gap requirements less significant (increased lead accuracy deviation). Therefore, the large screw is generally a single nut.
Iż-żift huwa d-distanza bejn żewġ ħjut ħdejn xulxin. Iż-żift u ċ-ċomb huma kunċetti relatati, iżda mhux ekwivalenti. Ħafna nies iħawdu żift u ċomb. Il-kunċett taċ-ċomb jirreferi għad-distanza li l-ġewż jimxi fuq il-kamin wara rotazzjoni waħda tal-kamin jew tal-ġewż. Jekk huwa kamin tal-ballun ta'-ras wieħed, il-pitch u ċ-ċomb huma l-istess. Fil-każ ta' kamin tal-ballun b'ħafna-ras, iż-żift taċ-ċomb=immultiplikat bin-numru ta' irjus tal-kamin. Jekk il-kamin jiċċaqlaq erba' (jew ħames) viti għal kull dawra, dan ifisser li l-kamin huwa kamin ta' erba-kamin (jew ħames-wajer), magħruf komunement bħala erba-ras (jew ħames-ras) kamin.
