Hi,
I’ve been reading the forum discussing this bearing and am still confused as to the best practice to be used.
My drive side bearing has 15 rollers each 8mm diameter and 8mm wide.
I thought they were 5/16” at first but the bearing catalogue for the NF series says it’s metric.
No maker’s name just R130 V3 and a ‘B’ see photos.
The bearings I see for sale have usually 13 rollers (NSK), 11 rollers (RHP), 14 rollers ( Draganfly, made in USA). But none with my original 15. And I counted twice just to make sure.
Looking through bearing catalogues it seems that along with common sense the greater the number of rollers the higher the load capacity and longevity.
My bearing looks reasonable, I had 0.003” end-float. The bearing was a firm push fit so no trouble putting a slightly thicker shim in to get the end-float within spec.
I’d replace it if I could find one like for like, just to be sure I’m not doing the job twice.
But I don’t want to replace it with a lower capacity, fewer rollers, item.
There seems to be many bearing manufacturers with names I don’t recognise and those I do seem to be like Hepolite where it’s just a name and unknown manufacturing source. Often they are advertised in plain plastic bags or simple cardboard boxes. Even my local bearing supplier seems to be buying Chinese items.
So who do I buy from?
Can anyone tell me the name of the original supplier to BSA?
What would you do?
Thank you,
Steve.
