Authoritative information on the actual type of bearings fitted in motors already supplied 1) Deep-groove bearings are used for regreasable designs (K40) (does not apply to 1LA6 up to size 160). 2/30 Siemens M 11 · 2003/2004 can be obtained from the factory by quoting the serial number or read off on the lubrication instruction plate of 1LA8 motors. 2) No deep-grove bearings are used for regreasable designs (K40). 3) Only at 50 Hz. When deep-groove ball bearings with sideplates are used, the sideplate is on the inside. Fig. 3 (page 2/34) shows the non-standard design with a located bearing at the drive end for 1LA5, 1LA7, 1LA9, 1MA6, and 1MA7 motors.
