Thrust bearing assembly-ball bearing height adjustable

What is a thrust bearing? And how to check if your turntable motor has a thrust bearing?
The pictures below will show you the difference :
A motor without thrust bearing / A motor with thrust bearing
Many of the older turntables (e.g. Planar 2, Planar 3 TT) or even some new models of the Rega(e.g. Rp1, P1, P2 TT's), Pro-ject and Linn TT's do not come equipped with motor thrust bearings.

P1 motor without thrust bearing
RP1 motor without thrust bearing
But in some other higher Rega models (e.g P3-24, P5 TT's), we find that the motors have thrust bearings built-in.
P3-24 motor with thrust bearing
P5 motor with thrust bearing
Should we overlook the importance of this small motor thrust bearing?
We might not know that without this thrust bearing the motor spindle(and pulley) tends to oscillate up and down as there is a vertical free play of 1 mm-1.5 mm. And this has hence resulted in speed "inconsistency'' when the pulley rotates.

Installation of the thrust bearing is simple; it's press-fitted onto the bottom part of the motor after adding one or two drops of light lubricating oil to the ball bearing.
This thrust bearing upgrade is also suitable for those models of TT's (e.g Pro-ject and Linn) which are using similar motors ( e.g. Philips, Premotec and Airpax etc ).

Hi
Thank you for your post. Do you have a link to where I could find the thrust bearing you used? My rega rp1 has a bit of a wobble and I think I may have finally found a solution!
Kind Regards,
Cara
