I am thinking about purchasing a new spindle the one listed here (CNC Spindle for CNC Router 2 2KW | eBay says it has NSK bearings and is about 100$ more than its competitor, This would be a good deal for me if they are genuine bearings can anyone tell me?

The one listed on the main website does not tell what bearing type it has 2200w 3HP Water Cooled CNC Milling Spindle, KL-2200 | Automation Technology Inc but the price is the same.
