Need Spindle Recommendation for Cutting Stone

The boss purchased an Off-Brand 3 axis CNC router for our stone business. The spindle failed with very few hours of use. Seems like the bearings failed. The spindle has no NEMA rating, probably has too little torque, and we suspect it isn't built to handle the special rigors of cutting stone. We'd like to replace the spindle with a more robust, properly rated unit. I am attaching the spec for the defective spindle. Any help will be appreciated. Thanks in advance !

Suggest Choose China 5.5kw cosntant water cooling spindle +water cooling system .
This type spindle is main for stone and aluminum .
