A follower mechanism for use in a bore of an internal combustion engine, including an outer sleeve having an inner surface and an outer surface defining a pair of axially extending shaft grooves that are formed in the inner surface and are parallel to a longitudinal center axis of the follower mechanism, an inner cup including a side wall defining a pair of shaft apertures, the inner cup being slidably disposed in the outer sleeve, a shaft having a first end and a second end, each of the first end and the second end extending through a corresponding shaft aperture of the inner cup and being slidably disposed in a corresponding one of the shaft grooves, and a roller follower rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the outer cup.

A cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.

A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly comprises a tappet body having a shelf and defining a pair of apertures, and a follower assembly. The follower assembly has a shaft, a first bearing and a second bearing, each supported on the shaft for engaging the camshaft lobe. A beam is further supported on the shaft between the first and second bearings and has a platform for engaging the fuel pump assembly. The shaft is disposed in the pair of apertures of the tappet body and the beam is arranged in the tappet body and engaged with the shelf.

A hand mechanism includes three-dimensional cams and claw portions configured to open and close in association with a rotary motion of the three-dimensional cams and achieves a compact and multifunctional configuration. A rotor shaft is a hollow shaft provided with a hollow shaft hole, is assembled in communication with a through hole formed in a cam base portion of a cam pedestal member, and is provided with a functional part in the hollow shaft hole.

A cam assembly is provided for a pick-up reel of an agricultural harvester. The cam assembly includes a cam track, a roller bearing assembly, a crank arm, and a biasing member. The roller bearing assembly includes a baffle and first and second cam followers. The first and second cam followers are each mounted to the baffle in spaced apart relation and engaging the cam track. The crank arm is for mounting to the pick-up reel. The biasing member biases the roller bearing assembly relative to the crank arm.

A roller assembly includes an outer ring having an interior having an inner surface extending an overall axial length between first and a second axial ends. The inner surface has a radially inward facing bearing surface extending between first and second radially inwardly extending flanges. The roller assembly includes a one piece inner member extending into the interior and having a groove formed therein between third and a fourth axial ends. A retaining ring is positioned in the groove. A first row of first rollers is positioned in the interior and between the retaining ring and the first radially extending flange. A second row of second rollers is positioned in the interior between the retaining ring and the second radially extending flange. An annular seal engages the inner member and has an overall axial width no more than 6% of the length of the outer ring.
