Apparatuses, systems, methods, and/or the like are provided for a transfer apparatus. An example transfer apparatus includes a bed having a first plurality of balls and a second plurality of balls having a first and second diameter, respectively, and wherein at least one of the first plurality of balls and at least one of the second plurality of balls are configured to rotate relative to the bed, wherein at least one belt of the plurality of belts is operably engaged with the at least one ball of the first plurality of balls or the at least one ball of the second plurality of balls; and a driver operably connected to the at least one belt of the plurality of belts, wherein the driver is configured to power the at least one belt of the plurality of belts.

A rolling-element bearing for an electromagnetic solenoid includes a hollow cylindrical cage with a plurality of spherical pockets formed around a first circumference and a second circumference of the cage. The pockets around the first circumference are offset from the pockets around the second circumference. Spherical rolling elements are provided in the spherical pockets and are captured for free rotation in the first pockets and second pockets.
