Bearing and associated sensor bearing unit

A bearing comprising:

• a first ring and a second ring centered on an axis, each of the first and second rings having an outer cylindrical surface, an inner cylindrical surface, and lateral faces which axially delimit the outer and inner cylindrical surfaces, wherein one of the inner and outer cylindrical surfaces and/or one of the lateral faces of the first ring comprise a textured area having two parallel first and second grooves extending radially or axially, a single inner protrusion disposed between and along the two parallel first and second grooves, a first lateral outer protrusion disposed alongside the first groove, and a second lateral outer protrusion disposed alongside the second groove, the first and second lateral outer protrusions extending respectively along the first and second grooves;
• wherein a height of the single inner protrusion of the textured area is bigger than heights of the first and second lateral outer protrusions.
