The present invention resides in a sensorized roller of a roller bearing. The sensorized roller includes a roller bore that accommodates a measuring device for measuring deformation of the roller bore and electronics for processing a deformation signal from the measuring device and wirelessly transmitting the processed deformation signal to an external receiver. According to the invention, the measuring device and electronics are mounted in a rigid housing that is shaped to fit within the roller bore. A radially outer surface of the housing includes at least one aperture associated with the measuring device. Furthermore, the rigid housing is resiliently mounted to the roller bore via first and second sealing elements that enclose a radial gap between a radially inner surface of the roller bore and a radially outer surface of the housing.

The invention relates to a method of forming a rolling element bearing cage assembly, comprising forming one or more segments, the forming of each segment comprising: forming a supporting frame having a plurality of spaced apart openings; forming a reinforcing frame including a corresponding plurality of openings each for aligning with the openings of the supporting frame; and inserting the reinforcing frame within the supporting frame.

A sleeve of a steering column includes (i) an outer tube and an inner tube that are movable relative to each other, and (ii) an adjustment system. The adjustment system includes a screw for adjusting the axial position along an adjustment axis constrained to move in translation with a first of the two elements by at least two guide bearings for rotationally guiding the adjusting screw about the adjustment axis. At least one of the bearings supporting the adjusting screw is a guide bearing with axial force take-up for blocking the translational movement of the adjusting screw.

A strain wave gearing unit has a unit housing, a strain wave gearing, and a bearing device. Balls of a bearing part of the bearing device are positioned on the diametrically outer side with respect to a cylindrical barrel part of an externally toothed gear. The diameter S of the balls is 0.05 to 0.15 times the pitch diameter D of the externally toothed gear. The centers of the balls are positioned between a point at a distance of 1.2 times the diameter S toward the cylindrical-barrel-part side from an inner-side end surface of a diaphragm along a center axis and a point at a distance of 1 times the diameter S toward a side opposite the cylindrical barrel part from the inner-side end surface. The bearing device can be configured to be used in common for strain wave gearing units having different axial lengths.

An outer ring case includes an annular guide groove housing an end of each of a plurality of inner rollers. A groove width representing a radial length of the guide groove is greater than a diameter of each inner roller. A radius representing a distance from a bearing axis to an inner wall face of the guide groove that is radially outer is smaller than a distance from the bearing axis to an axial center of each of rollers plus a radius of each inner roller.

A rotary table bearing 1 includes an outer ring 10, an inner ring 20, and a plurality of rollers 30. The outer ring 10 includes a first body portion 11 and a first steel strip 12. The inner ring 20 includes a second body portion 21 and a second steel strip 22. The first body portion 11 includes a first flange portion 53 of an annular shape that contacts a first end face 31 which is an end face of the roller 30 in the axial direction. The second body portion 21 includes a second flange portion 54 of an annular shape that is located to contact a second end face 32 which is an end face of the roller 30 opposite to the first end face 31 in the axial direction. At least one of an inner circumferential surface of the inner ring 20 and an outer circumferential surface of the outer ring 10 has a gear 114 formed over an entire circumference thereof.

The invention relates to a roller bearing cage comprising: a first annular ring; a second annular ring; at least one retainer portion attaching the first annular ring to the second annular ring to form the first and second annular rings in a cylinder-type structure; and a plurality of resilient tangs on each of the first and second annular rings, each tang protruding from the circumference of the respective annular ring at an angle with respect to the plane of the respective annular ring and toward the other annular ring.

This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.

An inner ring cooperates with an outer ring to form a roller bearing assembly. The inner ring comprises an outer circumferential surface receiving a plurality of roller bearing elements engageable with the outer ring upon forming of the roller bearing assembly. An inner circumferential surface of the inner ring is slideably mountable to a shaft upon forming of the roller bearing assembly and includes a base portion slideably engageable with a surface of the shaft upon mounting and at least one cutout portion opening to an outer edge of the inner circumferential surface. A clearance forms between a surface of the at least one cutout portion and the surface of the shaft upon mounting. Upon forming of the roller bearing assembly, the base portion of the circumferential surface is engageable with the shaft subsequently to the plurality of roller bearing elements engaging with the outer ring.

An ice maker includes a casing that defines a chamber. The casing extends between a top portion and a bottom portion. An extruder die is mounted to the casing at the top portion of the casing. An auger is disposed within the chamber of the casing. A radial sleeve bearing engages the auger at the bottom portion of the casing. A radial and thrust bearing engages the auger at the extruder die. A related refrigerator appliance is also provided.
