Abstract: A bearing having two rows of rolling elements has a flange extending outwardly from its outer ring. The flange is affixed to a facing surface inside of an aluminum housing, with a portion of the outer ring extending, with a play fit, in a bore of the housing.

Abstract: To determine the load distribution over the drilling head region of mining machines or roadheading machines the loads occurring at the individual roller drilling tools and simultaneously also the rotational running condition of the roller drilling tools are determined by determining the tangential deformations occurring at one of the races of a roller bearing associated with each tool. For this purpose, a measuring point with a strain gauge is associated with each roller bearing, that is, with either the outer race or the inner race of the bearing. With only this single measuring point, information is obtained on the magnitude of the load on the roller drilling tool and on its rotational running condition, this taking place via a great number of pulses per revolution. As a result, substantially more accurate information is obtained, as well as a simplification of the device from the constructional point of view, in comparison to prior devices.

Abstract: A rolling element bearing has annular seals between the races for preventing entry of dirt into the lubricant space. The seals are held to one of the races, and have weakened portions on at least one location about their periphery to enable excess pressure within the lubricant chamber to escape.

Abstract: A device for measuring axial force in a shaft journalled or mounted with two roller bearings arranged side by side in a housing, such measuring occurring by means of wire strain gauges or the like. The inner ring of the roller bearing on the shaft side engages a shaft shoulder, and the end faces of the roller bodies of the roller body row facing the bearing cover are supported by the flangeless inner ring of the adjoining roller bearing against a flanged ring or angle ring which is disengageably arranged on the shaft. This device is especially intended for wheel-set shafts of rail vehicles during travelling operation. Those end faces of the roller bodies of the two roller body rows facing each other are supported on a central flanged ring which transfers force and is movable in the direction of force when force is applied.
