A wheel bearing apparatus has a double row angular contact ball bearing. A height of a shoulder of a shoulder portion (18) of an outer member (12) with respect to a ball diameter of a double ball (14) row is set in a range of 0.35 to 0.50 mm. A corner (19) of the shoulder portion (18) has a relief surface (19a) and a chamfered portion (19b). The relief surface is on a straight line that is on a tangent line of an outer raceway surface (12a). The chamfered portion (19b) is round in a circular arc with a predetermined radius of curvature r. The corner (19) is formed simultaneously by a formed grinding wheel forming the double row outer raceway surface (12a). The corner is formed smoothly continuous from each outer raceway surface (12a). A length in the radial direction of the relief surface (19a) is set greater than or equal to 0.2 mm.

A programmable motion system is disclosed that includes a dynamic end effector system. The dynamic end effector system includes an end effector that is coupled via a dynamic coupling to the programmable motion system, wherein the dynamic coupling provides that at least a portion of the end effector may spin with respect to an other portion of the end effector.

A double-row angular contact ball bearing for a CT scanning device includes an inner member including a pair of raceway rings. The raceway rings have positioning holes into which a positioning member is inserted, to thereby suppress radial decentering of the raceway rings. Both the raceway rings are fastened by fixing bolts. The raceway rings have opposed end surfaces, and are fastened by the fixing bolts to bring the end surfaces into abutment against each other to apply a preload at a fixed position between balls and raceway surfaces. The following relationship is set: Db/h≦0.26, where Db represents a diameter of each of the balls, and h represents a radial dimension from a center of each of the balls to an inner diameter of the inner member.

A programmable motion system is disclosed that includes a dynamic end effector system. The dynamic end effector system includes an end effector that is coupled via a dynamic coupling to the programmable motion system, wherein the dynamic coupling provides that at least a portion of the end effector may spin with respect to an other portion of the end effector.

Radially outer ring of a bearing unit for a hub-wheel assembly for motor vehicles, the radially outer ring being provided with: a flange portion having a plurality of axial fixing holes that connect an element of the motor vehicle wheel to the radially outer ring, an almost cylindrical portion which with part of its radially internal surfaces defines raceways for rows of rolling bodies of the bearing unit, an axially internal or axially external surface of the flange portion and a radially external surface of the cylindrical portion connected to each other by a first portion of toroidal surface (St1) and of a second portion of toroidal surface (St2) defined by corresponding first radius (R1) and second radius (R2), a truncated cone surface (Stc) defined by an angle (a) formed with a rotation axis (X) of the radially outer ring is interposed between the first portion of toroidal surface (St1) and the second portion of toroidal surface (St2).

A pinion shaft assembly facilitates assembly of an automotive differential. An angular contact double row ball bearing is assembled to an outer surface of a hollow pinion shaft. An axial pre-load is established and maintained by orbitally forming an outwardly turned portion of the hollow pinion shaft. In some embodiments, the two inner rings are assembled to the pinion shaft. In other embodiments, a raceway may be formed directly on an outer surface of the pinion shaft to eliminate one of the inner rings. The pinion shaft includes a spline, such as an axial spline or a face spline, for fixation to a driveshaft.

A differential includes a unitized double row angular contact ball bearing supporting a pinion stub shaft. The bearing includes two inner rings which are slightly separated before assembly. As the stub shaft is inserted into the bearing, one of the inner rings is pushed against a land such as the back of the pinion gear. Pushing the inner rings together ensures a suitable pre-load. The inner rings have an interference fit with the stub shaft such that friction maintains the pre-load without a nut. The bearing and shaft are then inserted between halves of a two-piece case.

A turbocharger assembly can include a housing that includes a bore defined by a bore wall and a pin socket that forms an opening in the bore wall; a bearing that includes a pin opening defined by a pin opening surface; a pin, where the pin includes a longitudinal pin axis and a pin surface; a groove in the pin opening surface or the pin surface, where the groove includes an axial length; wherein, in a positioned state of bearing in the bore and the pin in the pin socket with part of the pin in the pin opening, a clearance exists between the bearing and the bore wall, where the groove is in fluid communication with the clearance to form a supply path for lubricant from the clearance to an interface between the pin surface and the pin opening surface.

A modular wheel-hub bearing unit having an outer flanged hub for mounting the unit on an upright of a vehicle, provided externally with an assembly surface and internally with a mounting seat; and a bearing provided with an outer ring, two inner rings and two rows of rolling elements arranged between the outer ring and the two inner rings. The bearing being mounted inside the assembly seat independently of the outer flanged hub and having an outer diameter, the dimensions of which are related to the dimensions of an outer diameter of the assembly surface of the flanged hub by a first coefficient (α) according to the relation: D2=α*D1, where 0.80≤α≤0.95.
