Abstract: A seal for a bearing assembly, including: a longitudinal axis; a first portion arranged to engage an outer ring for the bearing assembly; and a second portion extending radially inward and in a first axial direction from the first portion. The second portion includes: a first lip arranged to contact a rotatable shaft passing through the bearing assembly; and a second lip located past the first lip in a second axial direction, opposite the first axial direction, and arranged to be separated, in a radial direction, from the rotatable shaft by a first distance.

Abstract: A torque transfer assembly for a tandem axle drive train, having a first synchronizer assembly including a first portion arranged to non-rotatably connect to a power input shaft arranged to receive torque from an engine, a second synchronizer assembly, an overdrive gear assembly engageable with the first synchronizer assembly, and an inter-axle differential gear (IAD) arranged to engage first and second power shafts, and engaged with the second synchronizer assembly. In a differential mode, a first torque path is formed from the power input shaft to a first axle through the first synchronizer, the power shafts, the IAD and second synchronizer, and a second torque path is formed from the power input shaft to a second axle through the first synchronizer, the power shafts, and the IAD, and, in overdrive mode, a third torque path is formed from the power input shaft to the first axle through the first synchronizer.

Abstract: A method to ascertain measured friction torque to a bearing and a method to reduce preload variation of a hearing pair or set. Friction torque of a bearing is measured at a known load and speed. The value of the measured friction torque is then printed in a data matrix that is then applied to the bearing that was measured. Prior to assembling the bearings on a shaft system, the data matrix is read. The targeted friction torque is calculated for the shaft system based on the desired assembly preload. The bearing preload is then set and verified by measuring the friction torque of the pair of bearings assembled on the shaft. As a result of the method, bearing friction torque variation is substantially mitigated.

Abstract: A MacPherson strut tube having an upper spring seat, a spring, a strut tube, and a ring bearing disposed for engaging the spring seat, the spring and the strut tube. The ring bearing comprises an upper casing, a lower casing, and a plastic ring engaged between the upper and lower casings, thereby forming said ring bearing.

Abstract: System (1, 8, 20, 25, 30) for the securing of a roller bearing (2) in axial directions relative to a cylindrical seat (3), the system (1, 8, 20, 25, 30) with at least one first circumferential groove (4) of the seat (3) and with at least one securing ring (7, 19, 21, 22, 23), in which the securing ring (7, 19, 21, 22, 23) adjoins with a disk-form section (26, 27, 28, 29, 31) an axially outer side of a first bearing ring (10) of the roller bearing (2) and in which the securing ring (7, 19, 21, 22, 23) comprises elastically flexible first securing clips (11), projecting from the securing ring (7, 19, 21, 22, 23), which engage the circumferential groove (4).
