Evening all,
Sooo.. I am working on a project as we all are.
I have a shaft that rides inside a steel housing.
THe shaft has a small groove in it, and the entire thing rides in a bath of oil.
The shaft itself has a bearing surface with a shaft diameter of .71" Its a turned shaft, not ground. Also there are threads outside of the bearing surface, and .71 is the diameter of the threads also. So I cant turn the shaft down to a smaller diameter.
The housing itself is 1.27" OD.
What I need to try to do.. is put a thrust bearing on each end of it. I will turn it down the thickness of the bearing and or bearings and races. AND or bore the inside and put in a bearing Inside the housing.
So my original thoughts were to use a T shaped thrust bearing, that has a thrust surface on top and a needle bearing for the shaft itself. So I am getting thrust and axial loads handled by a single bearing.
However.... I am unable to comeup with any bearings that will fit that size requirement.
Option two I was thinking of... Oilite bearing for side loads. Bore the housing out, and turn down a oversize oilite to fit in the housing, also after boring the oilite to .71. When done slip it into the housing, and the shaft has lateral loads accounted for.
Part two of Oilite, option... to buy thrust bearings, that will be at each end. THe only size I have found are 17mm which is under the .71. Or 3/4 inch, obviously larger.
SO I was thinking.. get the .75 bearing and make a small insert/sleeve to center the bearing.. Or possibly leave a shoulder on the oilite that will center the thrust bearing.
Any ideas?
I have been searching bearing suppliers.. but basically they are 20mm x 35mm. Or 17mm x 30mm.
THanks all..
Scott
