Smart Grinder- Belt Grinder Small Wheel Holder Set Include Holder- 2 Idler Wheels. The distance between the mounting holes is 55 mm. And the hole diameter is 11 mm. Small wheels are "small" : and hence will rotate at much higher RPM than the Drive wheel RPM.
The smaller the wheel you use, the higher the speed. For example: If your drive wheel is 100 mm running at 3000 rpm motor, then the speed of the 12 mm wheel will be 25000 rpm. Therefore bearings will not last long if you don't have a way to reduce the drive wheel speed. It's a must that small wheels operate a much lower belt speed. The bearings can be replaced when they get worn-out.
Set Includes the following wheels dimensions. All wheels are 65 mm wide made from Steel.
