A thrust bearing comprises an electromagnetic stator with a stator surface and a rotor disk with a rotor surface facing the stator surface. The rotor disk comprises a radially inner portion made of a first material directly and exclusively connected to a radially outer portion made of a second material. The first material is a corrosion resistant metal or metal alloy and the second material is a ferromagnetic metal or metal alloy.

A method for preparing a surface of a substrate for bonding a material to the surface. The apparatus employed includes one or more optical amplification devices (OAD), one or more drivers, the substrate and a base. The one or more OAD and/or the substrate are moveably coupled to the one or more drivers. The one or more OAD is activated to emit a beam of energy. The one or more OAD and/or the substrate move relative to one another while the one or more OAD is activated. The movement of the one or more OAD and/or the substrate relative to one another forms (via the beam of energy) a pattern on the surface of the substrate. The pattern formed on the surface of the substrate allows the material to bond with a greater degree of adhesion.

A procedure for mounting of a hub bearing assembly having a rotatable hub, and a bearing unit having a stationary radially outer ring, and two bodies rolling crowns disposed between the radially outer ring and the hub. The assembly process involves the following steps: a) pressing-fit a first seal on the hub, b) mounting an axially external cage and the axially outside rolling bodies, in correspondence with a track of the axially outer hub, c) the radially outer ring assembly and inclination of the same outer ring of a predetermined angle with respect to the hub, d) mounting of the axially interior rolling bodies in correspondence with a track of the axially inner hub, and the radially outer ring alignment to the hub, f) snap insertion of the axially internal cage on rolling bodies and g) the pressing-fit a second seal on its seat.

Retaining clamps for retaining an over-molded plastic component to a substrate are disclosed herein that include a generally annular band having an inner surface, which defines an inner cavity for receiving a substrate rotatable about a central axis, and an opposing outer surface, which receives an over molded plastic component. The clamps have a plurality of axially extending retaining features formed in the annular band. The retaining features define a trough in the inner surface and a first crest in the outer surface or define a coupling portion forming a second crest. The retaining features are evenly spaced a distance apart along the generally annular band. A pulley body assembly is disclosed having a retaining clamp seated about an outer ring of a bearing for retaining a pulley body over-molded thereto. A method for over-molding a plastic component to a substrate using the retaining clamp is also disclosed herein.

A system and method that includes a device that is used in a particular method to install bearings into a lift cylinder yoke bore. The device includes use of a hollow bore hydraulic push cylinder that maneuvers a push plate along a threaded rod. The push plate sinks or sets into the bearing and applies pressure through the movement of the hydraulic push cylinder to place the bearing into a fit position without the abrasion that is usually associated with the installation of bearings into the lift cylinder yoke bore. The threaded rod attaches to a threaded bushing that is inserted into the bore and secured with the use of a pin. The threaded rod extends out of the bore opening and allows for the attachment of a bearing, push plate, hydraulic push cylinder, washer and nut.
