thrust bearing arrangement
(OP)
please tell me if we can arrange thrust ball bearings one above other in order to increase load carrying capacity ?
eg.: if i have a bearing of 100 lbs load capacity, can i use 4 bearings together one above another so that i can apply 400 lbs on it ?

If one bearing had 4 stacked raceways which might
be a nightmare manufacturing wise, there would be
load sharing assuming there was no moment load to
consider. In the case of 2 raceways in the same
bearing, the dynamic load carring capacity is generally
agreed to be 1.8 instead of 2.0, so I would assume
there would be continuous downgrading of the static load
carrying capacity.
If the bearings were just stacked, the top would see the 400
pounds and the second would see 400 pounds plus the weight
of the bearing above it, etc.

angular contact bearings will share the load
assuming all of the raceways are contained within
the same outer and inner rings or for strictly
thrust bearings you would need concentric raceways
in the upper and lower rings. Radial bearing are
used this way, but I have just begin to see applications
for windmills where they are using two row angular
contact bearings to share radial, thrust, and moment
loads.
