Information regarding spindle applications

● The following advantages are obtained by locating the gearbox outside the spindle box:
● Gearbox vibration is not transferred.
● Separate lubricating systems for the main spindle (grease) and selector gearbox (oil).
● No noise and no temperature fluctuations caused by the gearbox pinion wheels in the
● Instead of using belts, the drive power can also be transferred from the gearbox output
