1 pcs & 220380v AC 55kw ER25 Stone Working Water Cooled Motor Gas Nozzle Engraving Milling Grinding 4pcs ceramic ball bearings
There are 4 labyrinth seal in the front section of the spindlePrevents lubricant leakage from bearings and intrusion of harmful impurities (dust, moisture, corrosive gases) and bearing seals under high-speed conditions.
The have gas nozzle, so you can connect it to air pump, and the the dust difficult go into , good for stone working.

4 pcs ceramic ball bearing, extend the using life.
Iron casing, strong rigidity, suitable for products with high hardness
High precision,runout off less than 0.01mm.Coaxial degree less than 0.0025mm.
1. Our Ceramic ball bearings use 4 pcs ceramic ball bearings.
2. Ceramic ball bearings are to high temperatures and low heat, usually 3-5 degrees lower than steel ball bearings during using.
3. Ceramic ball bearings have low friction, low noise and long service life.
