I look in siemens documentation butIfind only this information: "Deep-groove ball bearing" no type nothing.It is necessery to change it every 2-3 years but anybody know it is possible to change by myself or i need to send whole motor to the service. With regards, makaveli

Where as Feed Motor it is risk of doing it....as it requires positioning to done...best way is to send it for repairs.... Regards, Ekalavya

I like Siemens controllers but the politics of company is always oriented towards to profit. They should put somewhere in doc what bearing they use in motors and how setup encoders. I know that with oscilloscope and analog outputs on drive is possible to adjust encoder. Do you know how to do that? With regards, makaveli

Whole motor need to be removed out completely…. if it is Feed motor alignment is required. I have not tried replacing bearing I have tried aligning the encoder at site it works… Attaching PDFand the docon web link... https://www.automation.siemens.com/doconweb/content.asp?item=13245&cd=sinumerik_simodrive_04_2010_e&scope=all Hope this may be useful.
