A bearing for holding a rotary conversion tool (10, 11) that includes two end rolling bearing devices (26, 28), at least one intermediate rolling bearing device (27) interposed between the end rolling bearing devices (26, 28), the end and intermediate rolling bearing devices (26, 27, 28) being intended to engage with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo′) at the intermediate rolling bearing device (27).

A rolling-element bearing with line contact includes bearing inner and outer parts having running surfaces, and at least one rolling element is disposed between and makes line contact with the bearing inner and outer parts. A width of the outer running surface and/or a width of the inner running surface is narrower at least in a first circumferential partial region than a length of the rolling-element, and in the first partial region the bearing outer part running surface and/or the bearing inner part running surface extends obliquely to a rolling direction of the at least one rolling element.

The present invention relates to a pressure roller bearing for a pallet car of a pelletizing machine. The bearing includes an external annular race having: an exterior surface for reversible mating engagement with a tooth gap of a wheel, a pair of sidewalls defining ends of the bearing, wherein the radial diameter of the exterior surface at a center portion in the axial direction is greater than the radial diameter of the exterior surface at the ends of the bearing, and an interior annular groove; an internal annular race defining a hole therethrough for receiving an axle, and having an exterior annular groove; and a plurality of rolling cylindrical members located in an interior space defined by the interior annular groove and the exterior annular groove when the internal annular race is received by the external annular race.

A mandrel for use in a printing apparatus includes a substantially cylindrical mandrel shaft and a locking assembly including a stop ring, a locking ring, and a plurality of deformable rings which are slidably and coaxially mounted on the mandrel shaft. Each deformable ring has a cross-sectional profile in a cross-sectional plane in which the mandrel shaft axis extends, which profile includes a first arm and a second arm which are integrally connected to each other at a first connection point. The first arm and the second arms include an angle which is sharper in the unlocked position than in the locked position of the locking assembly. The first arm has a first-arm-end remote from the first connection point, which defines the outer diameter of the deformable ring. The second arm has a second-arm-end remote from the first connection point, which second-arm-end defines the inner diameter of the deformable ring.
