English to French Tech/Engineering Mechanics / Mech Engineering Bearings

The text deals with bearings. Context is as follows:
"Cylindrical overshot bearings have a circumferential oil groove that extends across the top half of the bearing from an axial oil groove on one side of the bearing to another on the opposite side of the bearing. "

I've searched but cannot find an exact term for the translations. I was thinking of paraphrasing along the lines of "palier à rainure de circonférence pour lubrification".

Any better ideas?
