A sensor assembly includes a wear sensor and a seal member. The wear sensor has an encapsulation body with a wear face, a sacrificial conductor embedded within the encapsulation body and spaced apart from the wear face, and a monitoring lead extending into the encapsulation body and connected to the sacrificial conductor. The wear sensor is fixed relative to the seal member and the encapsulation body has a wear coefficient that is greater than a wear coefficient of the seal member. Bearing arrangements and methods of monitoring seal wear in bearing arrangements are also described.

The disclosure discloses a high-precision wheel assembling device, which is high in size and shape precision, good in dynamic balance, high in fatigue strength, good in rigidity and elasticity, light in weight, attractive in appearance and recyclable in material.

A gas blower includes a housing, a motor and a resilient sealing member for safety improvement. The housing has a receiving space and receives a fan wheel inside the receiving space, and the housing has an inlet and an outlet in communication with the receiving space. The motor has a base and a shaft. The base couples with the housing, and the shaft rotatably couples with the base and firmly connects with the fan wheel. The resilient sealing member is arranged between the housing and the base and is in a ring shape. The resilient sealing member has a central through hole for the shaft to extend through, a radial extending portion extending in radial directions of the shaft, a first surface and a second surface opposite to the first surface, with the first and second surfaces abutting against the housing and the base respectively.

A damper system may include an inner damper having a first annular geometry and a textured surface. An outer damper may also have an annular geometry and be disposed about the inner damper. The outer damper may have a textured surface. The textured surfaces of the inner damper and outer damper may define a cavity that is configured to contain a viscous fluid.

An end plate for an electric machine includes: a bearing receptacle in which a magnetic bearing which is configured for rotatably mounting a rotor of the electric machine can be accommodated; and a radially outwardly pointing circumferential contour on which a number of at least three supporting elements are provided, which supporting elements each protrude radially beyond the circumferential contour by a determined protruding amount, with the result that the supporting elements define a discontinuous external circumferential contour of the end plate. The respective protruding amounts of the support elements are dimensioned such that the end plate can be fitted in by making a center of the magnetic bearing correspond to at least one of a geometric longitudinal axis of the electric machine and a magnetic longitudinal axis of the electric machine.
