Rotae dentatae duplicis passi saepe ideales sunt ad spatium conservandum et diutius durant quam rotae dentatae communes. Aptae catenae longae passi, rotae dentatae duplicis passi plures dentes habent quam rota dentata communis eiusdem diametri circuli et detritionem aequaliter per dentes distribuunt. Si catena tua convectoria compatibilis est, rotae dentatae duplicis passi certe considerandae sunt.
Rotae dentatae pro catenis cylindricis duplicis passi praesto sunt in forma unius vel duplicis dentis. Rotae dentatae unius dentis pro catenis cylindricis duplicis passi eundem modum habent ac rotae dentatae normales pro catenis cylindricis secundum DIN 8187 (ISO 606). Propter maiorem passum catenarum cylindricarum duplicis passi, firmitatem augere potest per modificationes dentium.
