I have a skid steer trencher attachment whose front idler wheel came to me seized. Upon disassembly I was greeted with some chunks of bearing race and some balls and a pretty chewed up square shaft.
I ordered replacement bearings from the trencher manufacturer. They are NTN 5AS08-1, whose description is 1-1/8" square agricultural bearing. NTN shows the square to be 1.180".
Item # DC208TT5, Heavy Duty Disc Bearing - Square Bore, Cylindrical O.D., Type 5 On NTN Bearing Corp. of America
And the bearings I received appear to be something like that (it really looks like 1.185 on my calipers).
The shaft, in a non chewed up section, measures 1.13" square.
So what is the thought behind labeling a bearing 1-1/8", making it 1.18", and putting a 1.13" shaft in it? Seems wild to me.
Thanks,
