Siemens Motor Bearing Identification
Siemens Motor Bearing Identification
(OP)
I have a siemens 50 HP model RGZPSD motor whose nameplate indicates the following bearings:
shaft end: 60BC03JP3
op end: 50BC02JP3
The problem is my bearing supplier cannot identify this bearings, but the nameplate is clear enough so I have no doubt the numbers are correct. I searched SKF, Timken, etc. websites to no avail.
The motor is running right now, but I need to have the new bearings ready when we stop the motor, so I can´t wait until we stop the motor to verify the bearings. Can anybody identify this bearings? Thanks....

RE: Siemens Motor Bearing Identification
My advice would be for you to contact Siemens themselves and obtain them as spares like I ended up doing, you are then 100% certain they are suitable for the application.

shaft end: 60BC03JP3 = 6312 Z (C3)
op end: 50BC02JP3 = 6210 Z (C3)

RGZPSD is a standard off the shelf catalogue motor. We have several. No plastic cages or other strange features that I know of.

check out the following link:

click "mechanical data" and this will provide more info on the bearings (and everything else.
I think as electricpete says, I can't see anything special with the bearing. If there was a "-Z" at the end of the part number on the motor nameplate, then this would indicate there would be something 'non-standard' usually.
RE: Siemens Motor Bearing Identification
The motor we had in was special in that it was inverter rated and according to the name plate had a max speed of 5500 rpm so its quite possible that there was something special about them. I didnt actualy physicaly see the bearings so cant say for certain what made them special. I will find out though and post the answer.
