pillow block bearing insert rotation
(OP)
hello all,
new 40mm id bearings arrived today , they lack the locating peg ,that stops the bearing rotating in the spherical mount cast block .my concern is the bearing spinning in the block ,and wearing it .is this a new approach to have no peg on the outer surface ?
thanks
robert

RE: pillow block bearing insert rotation
For a bearing this small, I assume it is a ball bearing. It is probably grease lubricated. I do not consider it unusual that it lacks an anti-rotation pin. Most of the radial bearings in API pumps have a similar radial ball bearing with no pin stopping the outer race from spinning within the housing. Those bearings are in a cylindrical bore rather than a spherical seat. But, I don't see any reason why this would make a difference.

If the load direction continually varies in direction a pin won't prevent the micromotion. That's why keyed shafts by themselves don't last long.

after a fair bit of research by the supplier and i , it appears this peg is a bit of an unknown .some makes of bearings have it , some dont .the ones that dont work perfectly well .sometimes its associated with the grease hole being kept in a certain area ,so it would be fitted to a bearing that has no lube groove all around it . but some bearings have a groove ,and a peg !.
