When right now there is a big temperature fluctuation in the application form environment, when the diameter is huge or when right now there is load on its keyway, steel hub manufactured from S45C or stainless may sometimes be used. In these 
cases, one’s teeth part and the hub part are attached together with screws. If it’s not possible to screw collectively, two parts are fused jointly and made into fused gears. Ever-Power’s fused gears were created in such a way that the holding power of the fused surface is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, noiseless, injection molding enabling low priced and large production, and in a position to operate without lubrication by mating with metal gears. On the other hand, low strength, inclination to hold heat, large dimensional modify including backlash compared to metallic, etc. are a number of the factors requiring caution. The degree of dimensional changes that happen with plastic gears rely on the capability to resist temperature change, moisture absorption rate and resistance to chemical substances.
As far as the applications of Plastic Gear Rack plastic-type gears, they are found in varying industries such as food production machines, gadgets, chemical, toy, and medical equipment industries.
