Abstract: (EN) The invention relates to an installation device (3) for installing a sealing ring (1) on or in a component (2), for example a shaft or a housing, comprising a coupling member (4) for transmitting an installation force (F) to the sealing ring (1). The invention further relates to a sealing ring (1) comprising a rubber elastic base body (11) and a reinforcing ring (12), wherein the reinforcing ring (12) is embedded at least sectionally into the rubber elastic base body (11). The invention further relates to a method for installing a sealing ring (1) on or in a component (2), wherein the sealing ring (1) is inserted onto or into the component (2) in the axial direction.

Abstract: The invention relates to a welding device comprising electrode carriers (6, 12) which are actuated by a servomotor (9). The inventive welding device is characterized in that the servomotor (9) and the electrode carriers (6, 12) constitute a unit that is floatingly mounted on a linear guide (1) and that is maintained in a base position by means of equilibration elements (21).

Abstract: In a device for measuring forces by means of an anti-friction bearing which is provided with strain gauges at various measurement points, which serve to detect overroll extensions, two strain gauges connected as a half-bridge are used in each case, which are adapted to materials with different coefficients of expansion. By the use of such different strain gauges, temperatures and forces can be measured with one and the same measuring device, while force-dependent alternating-voltage fractions appearing at the center tapping of the half-bridge are filtered out of the total signal by a filter.
