The invention relates to a monitored roller bearing device, comprising a non-rotating race (), a rotating race (), at least one row of rolling elements () arranged between two rolling tracks () on the rotating race () and non-rotating race () and an information detection module, which comprises a non-rotating sensor unit () and a rotating () encoder (). Said device comprises a means for fixing the sensor unit () relative to a support (), by generating an axial force between a support surface () on the sensor unit () and a support surface () on the support (), while permitting an axial displacement of the sensor unit () relative to the support ().

Monitored roller bearing

An anti-friction bearing device comprising an outer ring ( ) provided with an outer surface and a bore on which a toroidal bearing inner race ( ) is formed, an inner ring( ) which is provided with a bore and a cylindrical outer surface on which a toroidal bearing outer race ( ) is formed, a row of balls ( ) which are disposed between the two bearing races, and a cage which can maintain a regular circumferential spacing between the balls. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the outer surface of the outer ring and the diameter of the balls ranges from 0.4 to 0.7. The ratio between the radial thickness of the outer ring, when taken between the bottom of the bearing inner race and the radial thickness of the inner ring when taken between the bottom of the outer bearing race and the bore of the inner ring ranges from 1.1 to 1.6.

Rigid anti-friction ball-bearing

The present invention provides an instrumented rolling bearing device having an outer ring, an inner ring, at least one row of rolling bodies arranged between two raceways of the outer and inner rings, and an assembly for detecting rotation parameters, this assembly having a non-rotating sensor unit and a rotating encoder member. The device allows for angularly immobilizing a non-rotating part of the device on a support while at the same time allowing relative axial movement of the device with respect to the support.
