Vertical Motor - Adjusting Endplay

[@TechTrainTracks]

GE has published that their recommended endplay range for their vertical hollow-shaft angular contact ball thrust bearings is .002 - .005". But from a practical standpoint this GE published range is considered by many experienced rebuilders to be too little endplay. So you may want to consider setting endplay at the .005" end of this range.

Hello. I need to disassemble a 400 kw high trust hollow shaft vertical motor with trust angular contact ball bearing. This is my first time and i need some advice and instruction. I would be grateful if you could help me.

That is very difficult advice to give online with so little info. There are so many different configurations out there. You almost have to see the motor itself. What kind of advice are you looking for?

Hi Sir, I need your advice, I replaced DE and NDE bearings for Vertical Motor (WEG) and when I made Solo run test, Abnormal sound happened in the motor By the way I used Springs bad quality for Thrust bearing, and also I don’t have references drawing which is showing the spring compression? Please your advice

We are having a difficult time trying to fully understand your situation to give you help. It sounds like you have a vertical motor with a spherical roller thrust bearing with Compression Springs? We have a video specific for just such a motor. Setting endplay on a vertical motor with spherical roller thrust bearings is very different from ball angular contract thrust bearings. Also, what id you mean by "...I used Springs bad quality for Thrust bearing"?

How do i set axial thrust when the thrust bearing is mounted on the rotor and on the lower end of the vertical hollow shaft motor

Reply from Reed NV GM: "So I have never seen a hollow-shaft vertical motor with thrust bearing located in the lower end of the motor. Have seen only Solid Shaft vertical motors with thrust bearings located in the lower end. They use shims on the top to keep the shaft from lifting up more that the end play amount. So the shims are on the upper bearing outer race and leave enough clearance for the setting. So if you lift the shaft up the shims would bottom out in the housing bore on top." Hope this helps answer your question.
