Small Wheels For 2×72″ Knife Making For Belt Grinder- Smart Grinder-5 Wheels Set
$76.80 VAT included (where applicable)
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. They are type 6200. You can easily source cheaply on eBay.
Set Includes the following wheels dimensions:
12 mm Diameter
15 mm Diameter
20 mm Diameter
25 mm Diameter
30 mm Diameter
All wheels are 65 mm wide made from Steel.
