Abstract: 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.

Abstract: 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.

Abstract: A bearing system for a rotating vertical shaft includes a first ball bearing, having a first pitch diameter and a first axial stiffness and a second ball bearing having a second pitch diameter and a second axial stiffness. The first ball bearing is a deep groove Conrad bearing. The second ball bearing is an angular contact bearing. The first and second ball bearings are coaxial, secured to one another and rotatable together. The first pitch diameter is at least 1.5 times greater than the second pitch diameter. The bearing system has an axial stiffness ratio defined by the first axial stiffness divided by the second axial stiffness. The axial stiffness ratio is based on an axial preload force applied to the second outer ring such that an operating torque of the bearing system is within a predetermined range at temperatures from minus 40 to positive 85 degrees Celsius.

Abstract: An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.
