Motor shaft and bearing

PMCtendo SZ synchronous servo motors have a smooth shaft end on the drive side (DIN
6885). Surface pressure needs to be achieved for torque transfer in the case of a positive
connection. This ensures a reliable transfer of force free of backlash.
The bearings are designed as ball bearings with lifetime lubrication and with non-contact
sealing.
