Bearing Design
Deep groove ball bearings, series 62 shielded on both sides (ZZ), with bearing clearance “Normal” are provided on motors up to and including 112M frame. Frame size 132 will be provided with C3 clearance.
The grease used is lithium complex soap-based, Exxon Mobil, UNIREX N3, to NLGI Class 3.
References for the bearings are given in the following table:
