An integrated hanger bearing monitor is provided for reducing installation time and added weight that includes a sensor and an interconnect on a mounting bracket that is sized and configured to be attached to a hanger bearing mounting bracket via connectors that mount the hanger bearing mounting bracket to the helicopter.

A bearing system includes a bearing housing configured to house a bearing and enclosing a free volume for receiving a lubricant, a bearing, a pump configured to pump lubricant into the free volume, a shaft in an opening in the housing rotatably supported by the bearing, an exclusion seal between the shaft opening and the shaft that is repeatably and non-destructively shiftable from a sealing state in which it substantially prevents lubricant from leaving the free volume and a release state in which it allows lubricant to escape between the exclusion seal and the shaft. The exclusion seal is caused to shift by increasing and decreasing a pressure in the bearing housing, and the system includes a controller configured to repeatedly shift the exclusion seal by raising and lowering the pressure in the free volume to continuously maintain a lubricating film between the exclusion seal and the shaft.

A bearing assembly is disclosed, comprising: an outer race and a plurality of rolling elements associated with the outer race. An inner race adapted to receive a shaft therein is rotatably disposed within the outer race such that the plurality of rolling elements are disposed between the inner and outer races. A cylindrical extension forming a plurality of tabs symmetrically arranged around the entire periphery of the extension is adapted to engage the shaft. A clamp collar that is installable around the cylindrical extension is defined by a circular wall with at least one threaded opening extending through the circular wall. The threaded member extends through one of the threaded openings to make contact with and apply a biasing force on one of the plurality of tabs towards the shaft when the shaft is disposed in the inner race to secure the inner race on the shaft.

A casing of a bearing unit for food applications may include a base having at least one hole for housing at least one fixing bolts, a spherical seat for housing the bearing unit, and at least one reinforcement rib located between the hole and the spherical seat.

A pillow block bearing seal for sealing the shaft opening around the shaft of a pillow block, having a stator assembly, a rotor, and a resilient cylinder sleeve. The stator assembly has a cylindrical base having an axial length that is configured to accept the shaft passing there through, and a stator extending annularly from an axial end of the cylindrical base. The rotor is configured to attach to and rotate with a rotatable shaft, and has an axially inward-facing surface that confronts the axially outward-facing surface of the stator to define labyrinth interface passage. The resilient cylindrical sleeve is fixed to an outer surface of the cylindrical base for contact with a pair of annular ribs of the bearing housing, for stabilizing the alignment of the center line of the shaft with the bearing housing.

A device for capturing and transmitting data of a bearing of a steel mill or rolling mill includes a sensor with a data processing unit arranged in a bearing housing capturing and storing data of a bearing. A data transmission unit in the bearing housing wirelessly transmits data of the sensor to a remote receiver. An energy receiving unit in the bearing housing receives energy wirelessly and transmits it to the data transmission unit and the data processing unit. An energy source with an energy transmitting unit arranged outside the bearing housing supply the energy unit wirelessly. The energy transmitting unit is covered by the bearing housing and is arranged on or in a structural part which adjoins the bearing housing and is part of the supporting structure of mill and remains on the supporting structure of the mill when the bearing housing is removed for maintenance purposes.

A flexible guide for a rotary resonator mechanism, in particular of a horological movement, the guide including a fixed support, an element movable relative to the fixed support, at least one main flexible strip allowing the movable element to move relative to the fixed support by bending the main flexible strip(s) in a rotary movement about a centre of rotation, the flexible guide being arranged substantially in a plane, and includes at least a first translation table joined to one end of the main flexible strip, so that the first translation table is configured to move in translation at least in part under the effect of the bending of the main flexible strip, the flexible guide including a device for adjusting the rigidity of the first translation table.

A sensorized supporting device for bearings (1) comprises: • a bearing housing (2), configured for being secured to a mounting structure and defining at least one seat (2c) for a bearing (3); and • a sensorized supporting base (4), having a supporting body (4′) prearranged for being at least partially positioned between the mounting structure (S) and the bearing housing (2). The supporting body (4′) has a detection surface (4c) which extends in a longitudinal direction (L) and a transverse direction (W) and is configured for resting, directly or via interposition of at least one further element, on a corresponding surface of one of the bearing housing (2) and the mounting structure, the supporting base (4) being provided with a mechanical-stress sensor. The mechanical-stress sensor comprises at least one piezoelectric transducer (10.sub.1, 10.sub.2, 20) defining at least part of the detection surface (4c), the at least one piezoelectric transducer (10; 20; 10.sub.1, 10.sub.2) being configured for generating an electrical potential difference that is substantially proportional to the magnitude of a mechanical stress (SS) applied to the bearing housing (2).
