  • Cageless thrust bearing with unguided rollers
    Patent number: 4120542
    Abstract: The cageless thrust bearing with unguided cylindrical rollers comprises a pair of thrust bearing races with axially separated flat thrust raceways. Cylindrical rollers all having the same diameter are located between the separated flat thrust raceways. The spacing of the rollers is such that the rollers become radially aligned in the bearing under a rotating thrust load, without side or end guidance of the rollers.

  • Roller thrust bearing cage and roller assembly
    Patent number: 4077683
    Abstract: The roller thrust bearing cage and roller assembly includes an annular cage with a plurality of circumferentially spaced pockets. Each of the pockets is shaped to give proper guidance to the roller when the extended center line of the roller passes through the axis of the annular cage. Preferably each pocket has two radially, inwardly converging sides and preferably, the pockets are trapezoidal. A cylindrical roller is preferably located in each of the pockets.

  • Separator ring for retaining rollers in a thrust bearing
    Patent number: 3999817
    Abstract: The separator ring to be used with thrust bearings is an annular member with a plurality of circumferentially separated roller engaging portions. The rollers have outer ends constructed to mate with the roller end engaging portions of the annular member. The roller engaging portions on the annular member may be protrusions extending radially inwardly toward the axis of the bearing with the rollers having depressions on the outer ends for receiving the protrusions or alternatively, the roller engaging portions may be radially outwardly extending depressions with the rollers having outer surfaces which fit into the depressions.

  • Thrust bearing with locking tabs
    Patent number: 3994546
    Abstract: This is a two-piece roller thrust bearing cage. Two retainer members, each with a plurality of circumferentially separated pockets which are aligned, are held against relative circumferential movement by one or more locking tabs extending from one retainer member into one or more pockets in the other retaining member.

  • Method of making a thrust washer
    Patent number: 3981060
    Abstract: The thrust race comprises circumferentially spaced tabs on the outer flange with cutouts located circumferentially adjacent each side of each tab.The thrust race is formed from sheet metal. Annular blanks are blanked in the sheet metal, the cutouts are made on the outside perimeter of the annular blank, the tab between each pair of cutouts is formed, and the annular blank then removed from the flat sheet metal. The outer portion of the annular blank is bent to form an axially extending outer flange having a plurality of circumferentially spaced tabs extending inwardly from the flange toward the bore of the thrust washer with cutouts located circumferentially adjacent each side of each of the tabs.
