Notes

Built-in FANUC motors can be either customer-supplied or sourced by NSS.
When lubrication is "Oil", a separate oil mist supply unit is required.
Although not listed in the table above, motor built-in spindles generally require stator and bearing cooling via a coolant oil circulation unit.
An air cylinder for tool unclamp is standard equipment. However, BT/BBT30 and BBT40 basically use hydraulic cylinders.
The above is an example. Custom specifications are also available — please submit the spindle unit inquiry form at the bottom of the contact page with your desired specifications.
