A bearing unit for a marble cutting machine has a radially outer ring, rotatable with respect to an axis of rotation (X) and is provided with a radially outer flange portion. Additionally, the bearing unit is provided with a stationary radially inner ring with a through hole in which the ratio between a dimension of an internal diameter (D) of the through hole and a dimension of the axial thickness (T) of the radially inner ring is between about 6.7 and about 11.1. A row of rolling bodies is interposed between the radially outer ring and the radially inner ring. A sealing shield is made of composite material and interposed between the radially inner ring and the radially outer ring, rotatable with respect to the rotation axis (X) and steadily anchored to the radially outer ring. The shield is provided with a sensor molded in it.

Tooling for clocking dual eccentric bushings of a clevis so that the clevis and a lug can be pinned together, comprises a pin and a sleeve. The pin comprises a pin cylindrical portion, a plate-engagement portion, and a stop surface. The sleeve comprises a sleeve cylindrical outer surface and a sleeve interior channel that has an interior-channel central axis, which is parallel to and offset from a sleeve-cylindrical-outer-surface central axis. The pin cylindrical portion is configured to be received by the sleeve interior channel with a slip fit. The tooling further comprises a squaring plate that comprises a squaring-plate abutment surface, configured to contact the stop surface, and a squaring-plate opening configured to receive the plate-engagement portion of the pin with a slip fit.

A pumping device includes a single-use device and a reusable device. The single-use device is to be inserted into the reusable device and includes two pump units in series, one behind the other. Each pump unit includes a rotor for a bearingless motor, and can be magnetically levitated and driven without contact for rotation about an axial direction. The reusable device includes a stator for each rotor which form an electromagnetic rotary drive for rotating the rotor about the axial direction. Each stator is a bearing and drive stator with which the rotor can be magnetically driven and levitated without contact with respect to the stator. An independent control device is provided for each stator, and can independently activate a respective stator.

A bearing monitoring apparatus including at least one interface for receiving strain signals detected by at least one strain sensor mounted on a bearing and at least one data processing unit configured to monitor the bearing by detecting bearing defects based on the strain signals is provided. The data processing unit is configured to subject the strain signal to a high pass filtering. A limit frequency of the high pass filter is set higher than a typical ball pass frequency of the bearing to be monitored, to calculate a quantity representative of the amplitude of the envelope signal of the high-pass filtered strain signal, to compare the peak hold of the envelope signal with an envelope threshold value, to classify the bearing using the result of the envelope comparison and to issue at least one warning signal if the bearing is classified as defective.

A rotating shaft assembly comprising a rotating shaft 1 mounted within a casing, and a primary bearing assembly in bearing engagement with the shaft and the casing and positioned between the shaft and the casing; the assembly further comprising a secondary bearing assembly comprising a secondary bearing normally radially spaced from the shaft and arranged to engage with or contact the shaft in the event of failure of the primary bearing normally in contact with the shaft, and means for insertion and/or removal of an inspection member to provide an indication of frictional engagement of the secondary bearing with the shaft.

Improved systems and methods facilitate precise adjustment of wheel-end tapered roller bearing preload force on an axle spindle with a diameter, a longitudinal groove or flat, and a thread pattern to receive a hexagonal adjustment nut with six outer edges. A basic system includes a flat round inner washer having an inner diameter corresponding to the diameter of the axle, an outer diameter, an inner surface, and outer surface and an outer edge. The inner washer includes a tab or D-shape to cooperate with a groove or flat, respectively on the axle to ensure that the washer does not rotate following installation. A plurality of markings are provided on the outer surface or the outer edge of the inner washer, each marking indicating the amount of rotation needed to cause a 0.001″ lateral movement of the adjustment nut as a function of the diameter and thread pattern of the axle.

The invention relates to a method for producing an axle housing of a vehicle axle, by means of integrally connecting an axle tube (1) to an axle shaft (2) which is positioned on the longitudinal axis (L) of the axle tube, is equipped with bearing surfaces (3) for mounting a vehicle wheel, and has a tube cross-section facing said axle tube (1) which is substantially the same as the tube cross-section of the axle tube. In order to develop a welding method for the production of an axle housing that consists of an axle tube and an axle shaft secured thereto, which method is optimised in terms of the dynamic loads to which the axle housing is typically subjected in a driving operation, the method comprises the following steps: •—arranging the axle tube (1) and the axle shaft (2), with the abutting surfaces of their tube cross-sections positioned coaxially to one another, in a workpiece receiving portion of a welding installation (10), said welding installation additionally comprising an arc welding device (11) and a laser welding device (12) which is operated in parallel, •—continuously miming a weld seam (20) in the peripheral direction of the tube cross-sections, both welding devices (11, 12) being directed, actively and from the outside, onto substantially the same peripheral section of the abutting surfaces, wherein the laser beam (S) meets the outside (14) of the tube at right angles, and intersects the longitudinal axis (L) of the axle tube (1), and •—stopping running the weld seam (20) once this has passed over a peripheral angle of at least 360°. A corresponding axle housing is also disclosed.

In one aspect, the present disclosure provides a sliding bearing system, comprising (a) a base plate, (b) one or more force measuring sensors, wherein each of the one or more force measuring sensors includes a top surface and a bottom surface, and wherein the bottom surface of each of the one or more force measuring sensors is coupled to the base plate, and (c) a first sliding surface coupled to the top surface of each of the one or more force measuring sensors.

A bearing assembly includes a first bearing ring and a second bearing ring that are movable with respect to each other, and at least part of the first bearing ring and/or at least part of the second bearing ring is provided with a first thermochromatic coating that has a first color in a first temperature range and a second color in a second temperature range.

A bearing includes a first ring, a second ring, at least one row of rolling elements arranged in a rolling chamber disposed between the first ring and the second ring, and a cap attached to the first ring that is configured to close the rolling chamber. At least one vibration sensor is attached on the inside of the cap, and the vibration sensor is mounted in a metal block connected to the cap.
