External Drive Spindle

Name: External Drive Spindle
Brand: N・S・S Co., Ltd.

Available in a wide range of sizes from large to compact models — spindle units suited not only for machining centers but also for purpose-built dedicated machines.

With no internal motor, the choice of drive motor is unrestricted, giving these spindles exceptional flexibility in drive method. Both coupling and belt-drive configurations are supported, making them well-suited for dedicated machines that require maximum torque at a specific RPM tuned to particular machining conditions.

Although not listed in the table above, stator and bearing cooling via a cooling oil supply unit may be required.
Drive methods include belt drive (speed reduction/increase available) and direct coupling. Please contact us for details.
