Abstract: A bearing assembly includes an outer race and an inner race. The outer race has a body extending between a pair of axial faces and defines a radially-inward facing bearing surface. The inner race is received in the outer race and has a radially-outward facing bearing surface that bears against the radially-inward facing bearing surface of the outer race. The radially-outward facing bearing surface has one or more flat surfaces removed from it. These flats on the inner race can reduce the dimensional entry requirements for insertion of the inner race into the outer race and either permits the receiving slots in the outer race to be reduced in dimension (thereby relatively thickening the wall of the outer race, which structurally strengthens the outer races) or permits the receiving slots to be eliminated altogether.

Abstract: An assembly is provided for a piece of rotational equipment with an axis. This assembly includes a static structure, a bearing within a bore of the static structure, and a centering spring mounting the bearing to the static structure. The static structure is configured with the bore, a slot, a first slot surface and a second slot surface. The slot extends radially into the static structure from the bore. The slot extends axially within the static structure between the first slot surface and the second slot surface. The centering spring includes an annular hub and a mounting tab. The annular hub is within the bore. The mounting tab projects radially from the annular hub into the slot.

Abstract: A button assembly includes a touchpad having an upper surface extending in a generally flat plane and movable between a first position and a second position displaced from the first position in response to the application of a pressing force perpendicular to the upper surface. Additional, smaller pushbuttons may be located adjacent the touchpad. A sub-bezel includes a housing defining a cavity for holding a linear bearing for guiding the touchpad in a linear path perpendicular to the upper surface. The linear bearing includes a plurality of first ball bearings and second ball bearings separated by a first distance perpendicular to the upper surface. The ball bearings may be sandwiched between a bearing outer member and a bearing inner member which includes an inner-top member secured to an inner-bottom member with a screw. A bearing carrier holds the ball bearings within troughs in the bearing outer member.

Abstract: A method of manufacturing a slotted entry bearing assembly includes inserting an inner race into a central space of an outer race. The outer race is configured to receive the inner race through at least one slot. Once the inner race is fully inserted into the outer race, it is rotated approximately ninety degrees within the center space, effectively locking the inner race within the outer race. After the inner race is rotated ninety degrees, a molded seal is molded between the inner race and the at least one slot. The molded seal adheres to the at least one slot and is made of a polymeric material. The molding process used to mold the molded seal may be compression molding.

Abstract: The ball socket assembly includes a housing with an open interior which extends along an axis. A bearing is disposed in the open interior of the housing and has a curved primary contact surface which surrounds the axis and surrounds a stud ball opening. A stud ball is disposed in the opening and is in sliding contact with the primary contact surface for allowing rotation of the stud ball relative to the bearing. The stud ball has an equator and is in sliding contact with the bearing on both sides of the equator. A stud is operably connected with the stud ball. A shoe is further provided and has a pair of supplemental contact surfaces that are biased against the stud ball. The shoe provides the stud with a predetermined rotational torque and also adjusts for wear in the assembly to maintain the performance of the socket assembly.
