Examples are directed to detecting an oil film state of a bearing device. An arrangement obtains background impedance, background admittance, static and dynamic admittance, and determines electrical contact resistance for a rolling element. When the electrical contact resistance is greater than the high resistance value, the arrangement calculates inner capacitance and outer capacitance from the impedance or the admittance; calculates central film thickness in the contact region; and calculates inlet distance and dimensionless meniscus distance. The arrangement determines when the inlet distance is not less than the dimensionless meniscus distance and stores the central film thickness. When the inlet distance is less than the dimensionless meniscus distance, the arrangement recalculates the central film thickness. When the electrical contact resistance is not greater than the high resistance value, the arrangement calculates inner capacitance and outer capacitance from the impedance or the admittance; and determines and stores the central film thickness.

A system for determining an absolute position of a device includes a high resolution track (14), a sensor and processing unit (22) associated with the high resolution track (14), a reference track (18) having a plurality of pole pairs arranged to define a single-track Gray code segment, and an array of Hall effect sensors (26) associated with the reference track to output a reference signal to the sensor and processing unit indicative of the coarse absolute position of the device over the single-track Gray code segment. The sensor and processing unit (22) combines the reference signal with the position of the device over the high resolution track to determine an initial, fine absolute position of the device. An up/down hardware counter (34) increments the initial fine absolute position using a signal generated from the high resolution track, and without any further software-based processing, to maintain and continuously update the fine absolute position of the device.

At least some of the bridges include a projection on a radially inner side such that the plurality of proj ections together define an inner diameter of the cage, the inner diameter of the cage being smaller than the outer diameter of the inner ring to create interference and deformation of the cage as the cage is installed over the flange of the inner ring.
An apparatus for preloading a bearing assembly on a shaft includes a first annular threaded member positioned about the shaft and a second annular threaded member positioned about the shaft. The first and second threaded members have intermeshing threads such that rotation of the second threaded member causes axial translation of the first threaded member to apply a first axial force to the bearing assembly to preload the bearing assembly. An actuator is operable to rotate the second threaded member relative to the first threaded member to apply the first axial force to the bearing assembly.
