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.

Maintenance free extended life cam follower for a necker machine

A cam follower for a ram of a metal can necker machine is provided. The cam follower has an outer ring and an inner ring coaxially disposed in the outer ring. A plurality of rolling elements is disposed in an annular cavity between the outer ring and the inner ring. The plurality of rolling elements is disposed between a first seal and a second seal. A shaft is received in a bore in the inner ring and is fixed relative thereto about the shaft axis. The outer ring is received in a tire. The tire has a thickness and a crown radius. The composition of the tire includes a metallic material, a plastic material, a non-metallic material, and combinations thereof.

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.

Ball bearing cam follower for an adjustable aircraft seat

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.

Bearing system for an articulating motor device

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.

Cam follower and yoke roller assemblies

A bearing assembly for a cam follower assembly for a ram assembly for a metal can production necker includes two or more bearings. Each of the bearing includes an inner ring positioned within an outer ring and a plurality of rolling elements positioned therebetween. The bearing assembly includes a tire press fit on the outer rings of the bearings. The tire has an elongate body portion that extends between a first radially inward projecting shoulder and a second radially inward projecting shoulder. A radially inward facing surface extends between the first radially inward projecting shoulder and the second radially inward projecting shoulder. The first radially inward projecting shoulder extends further radially inward than the second radially inward projecting shoulder.

Cam follower with tire having axial movement compensating features

An extended life ball transfer unit has a housing with a well of generally cup-shaped configuration with at least the lower portion of its surface being defined by a pair of radii mutually offset to opposite sides from its vertical axis to generate a gothic church arch cross section. A passage extends therethrough at the base of the housing well. Sealed in the well is a spherical conveyor ball having a radius of smaller length than the radii defining the lower surface of the well, and the well defining radii having their origins above the center of the conveyor ball. A multiplicity of spherical bearing balls is disposed between the conveyor ball and at least the lower portion of the well. The bearing balls support the conveyor ball and transferring the load from the conveyor ball to the housing over an annular area defined by an arc of about 5-15&#xb0; with its center spaced about 30&#xb0;&#x2013;40&#xb0; upwardly from the passage. A annular cap is seated in the upper portion of the well and has an inner surface portion bearing against the surface of the conveyor ball to provide a sealing action limiting debris from passing into the lower portion of the well.
