1, order synchronous belt wheel need to provide parameters: number of teeth, tooth shape, the width of the belt used, the size of the inner hole.

2, synchronous pulley tooth shape has two kinds of British and metric, so the basis of division is because of their different torque, metric torque relative to the British system may be a little higher. It is precisely because they have these two aspects of the difference, so that customers can choose and determine their own needs according to their own will.

3, the number of teeth is an important guiding standard for the selection of synchronous pulley, the number of synchronous pulley teeth on the market is basically uniform distribution, in all aspects are not very different, although in the choice of time or to see if he is damaged.
