Abstract: A bearing tracking system and method are provided, in which a bearing tracking application program is executed on a computer system to process information requests from a variety of system users received over communications links such as the Internet, and to present the users with an interface, such as an Internet browser page, containing output from processing bearing-related information stored in a database preferably hosted and maintained by the bearing supplier. The users may include different categories of entities, each with their own rights and responsibilities, such as customers or end users, third-party maintenance and refurbishing service providers, and organizations of the bearing supplier, such as engineering and marketing organizations.

Abstract: A device and method for monitoring machine components, such as bearings, in which micro-electronic monitoring devices are provided in contact with or within the component to be monitored to acquire and transmit performance data, preferably wirelessly, to a receiving device. The acquired information, which may be accompanied by unique monitoring device identification information, may be further processed and presented to an operator in human-interpretable form. The monitoring data acquisition may be conducted over dedicated communications circuits, or may be conducted, for example, by bringing a suitable receiving device, such as a receiver-equipped PDA, within data transmission range of the monitoring devices.

Abstract: A hydraulic nut having a piston which is movable in a fluid chamber of a nut body and which has a radial protrusion from the piston and a displacement bar mounted on the protrusion. The displacement bar overlies the nut body and extends past the nut body by an amount equal to the distance through which the hydraulic nut is to move a bearing assembly along a tapered shaft or move an adapter sleeve, or removal sleeve with bearing assembly on them.
