Abstract: A pinion mounting with direct tapered roller bearing arrangement for differential gear mechanisms includes a first tapered roller bearing and a second tapered roller bearing to provide support for a pinion shaft, the pinion mounting and pinion shaft being removable from the differential gear mechanism without disassembly of other components of the differential gear mechanism. The first tapered roller bearing incorporates a continuous seal and o-ring, with the first tapered roller bearing either mounted to the differential gear mechanism case by retaining a mounting flange on the bearing cup, or threaded into the differential gear mechanism case by threads on the exterior of the bearing cup. A plurality of shims are used to set the bearing preload and to dimensionally set a pinion shaft gear with a ring gear of the differential gear mechanism.

Abstract: Rolling element bearings capable of both axial and radial restraint are readily removably mounted on the shaft of each screw rotor so as to allow a clearance type radial fit between the bearing and shaft. A washer engages the inner race of the bearing which also engages a shim. A bolt squeezes the inner race between the washer and shim to secure the bearing in place while the shim thickness/height determines the position of the rotor within the casing.

Abstract: A radially disposed thrust bearing assembly for air cooled and lubricated mining type rotary cone rock bits consists of a first non-rotating radially disposed steel thrust bearing disc and an apposed, non-rotating carbide thrust bearing disc. One of the thrust bearing discs is pressed into a disc retention socket formed in the end of a spindle bearing extending from the end of a main axially aligned bearing cantilevered from a leg of the bit and the other thrust bearing disc is pressed into a disc retention socket formed in the rotary cone. An edge of the carbide disc is formed with large valleys and peaks, the robust undulations resist cracking when the carbide thrust bearing disc is pressed into its respective socket. Unique air passages and channels are formed in the main and spindle bearings to direct cooling air to the apposed thrust bearing discs.

Abstract: A combination of two angular type ball bearings provided in a face-to-face arrangement to form a ball bearing unit in which the diameter of the balls of the second ball bearing is less than the diameter of the balls of the first ball bearing.
