• NOTE:There is an error between the technical size and the particular length NOTE: Data parameters have error ± 0.05 to 0.1mm for example :X-2A X-1A X-2B X-1.5A X-2.5A 1.X : Number of tooth 2.A: tight with， 2A Aperture=2-0.05=1.95mm,1A Aperture=1-0.05=0.95mm，1.5A Aperture=1.5-0.05=1.45MM , 2.5A Aperture=2.5-0.05=2.45MM 3.B: loose with ​， 2B Aperture=2+0.05=2.05mm 2A: shows the central axis of 1.95mm;fit to 2mm optical axis, with a tight, rotates together with the optical axis. Gear diameter = (number of teeth +2) * 0.5 ( mm) for example：30-2A（30 is tooth ，aperture is 1.95mm） Modulus:0.5 d(Aperture):1.95MM
