    摘要： The rolling bearing comprises an inner ring 1, an outer ring 2, at least one row of rolling elements and at least one seal 7 provided between the outer and inner rings. The seal 7 has, in cross section, the overall shape of an H and comprises internal lips 21, 22 and external lips 23, 24 forming the two substantially parallel branches of the H. The inner and outer rings 1, 2 comprise opposite radial ribs 25, 26 located axially between the internal and external lips 21 to 24 to axially retain the seal.

    摘要： A seal device for sealing in a liquid medium includes a first seal assembly disposed on a primary side facing the medium and configured to seal a stationary component with respect to a rotatable component, a second seal assembly disposed on a secondary side facing away from the medium and configured to seal the stationary component with respect to the rotatable component, and a sensor connected to a volume located between the first seal assembly and the second seal assembly and configured to detect a change of a moisture level in the volume. The stationary component further includes a bore located axially between a contact surface for the first seal assembly and a contact surface for the second seal assembly, and the volume is connected to a pressure tank by the bore.

    摘要： A seal assembly for sealing a grease lubricated large rolling-element bearing includes a radial shaft seal having at least one seal lip configured to sealingly abut against a shaft to seal a bearing interior and substantially prevent a grease discharge from the bearing and a grease flow regulation device, such as an annular pumping ring, for regulating a grease pressure at the at least one seal lip, the grease flow regulation device being mounted adjacent to the radial shaft seal at a side of the radial shaft seal that is intended to face the bearing interior in an installed state.

    摘要： A seal assembly for sealing between first and second tubular members includes an annular seal body disposeable within an annular gland between the tubular members and formed of a generally compressible polymeric material. The seal body has a first axial sealing surface disposed against a first tubular member end surface, a second axial sealing member disposeable against a second tubular member end surface and a recess(es) defined partially by an angled activation surface. An annular backing ring formed of a substantially rigid material is disposed the body recess to couple the backing ring with the seal body. The backing ring has an outer axial end disposeable against the first member end surface to prevent radially outward displacement of the portions of the seal at the first member end surface and is biased axially toward the first member end surface when compression of the seal body displaces the activation surface axially.
