GT2 Timing Belt Pulley

Reduction ratio description: for example, 1:5, then it is 16 teeth and 80 teeth; 1:3 can be 20 teeth and 60 teeth. 

It is convenient for you to design and produce! The shop synchronous wheel workmanship is fine, do not fear comparison! For example, if you want to make 1:3 speed reduction, then you can buy 20 teeth and 60 teeth.

Synchronous belt pulleys can be used in a variety of long-distance transmission models. Nice little parts for tech modelling, personal crafting!

Each synchronous belt wheel are sent machine rice screws, an order only send a spanner Oh! (16 teeth using the M3 machine rice screws and spanners, 20, 25, 30, 40 teeth, 60 teeth using the M4 machine rice screws and spanners)

Note: Synchronous wheel does not include synchronous belt, need synchronous belt, synchronous belt to the shopping cart to submit the purchase!
 
Model: 2GT, Pitch: 2mm , Tooth shape: Trapezoidal, Belt width: 6MM (for 6MM synchronous belt) 

Outer diameter of teeth = number of teeth * pitch / 3.1415 - pitch / 4
