Note：the drawing does not represent the real object, just show the parameters of the gear

There are two kinds of M0.3, 48 teeth gears with 1.0 shafts, one is a standard 48T with an outer diameter of 15mm

The outer diameter of the non-standard 48T is 14.5mm

This is non-standard 48T gear

Two kinds of M0.3, 48T gears with 1.0 shafts，the standard gear on the left is a bit bigger

The outer diameter of the standard 48T gear is 15mm, and there is a calculation formula for the gear: outer diameter D=(T+2)xM, T refers to the number of teeth, M refers to the modulus

The outer diameter of non-standard  48T gear is 14.5mm

The thickness of the two gears are also different, the standard 48T is 1mm thick, and the non-standard 48T is 1.5mm

The standard 48T weight is 0.21g

The non- standard 48T weight is 0.28g
