A seal body includes a flange that supports a lip configured to make sliding contact with a fixed surface. The flange includes a groove for receiving a garter spring on one face, and inwardly and outwardly facing conical surfaces on the opposite surface, the conical surfaces defining a lip where they meet. The ratio of the thickness of the portion of the lip located to one side of a plane that includes an edge of the groove to the thickness of the portion of the lip on the other side of the plane is about 44%.

In a sealing device having a combination of a seal lip and a seal flange which slidably come into contact with each other, and having a thread groove in an axial end face of the seal flange, the seal lip installed to a not-rotating housing side slidably comes into contact with an axial end face of the seal flange in a rotating shaft side, and the thread groove achieves a fluid pumping action at the rotating time in an axial end face of the seal flange. The thread groove has an inner peripheral side inclined surface as a part of an inner surface thereof, and an angle formed between an inner peripheral surface of a leading end portion of the seal lip and the inner peripheral side inclined surface is set to a range of 0 degree3 degrees. The sealing device can suppress generation of a static leakage.

A seal assembly extends along an axis and seals an axial (and/or radial) gap between a first component and a second component. The seal assembly includes a seal carrier and a seal element. The seal element extends axially (and/or radially) between a first portion and a second portion. The first portion of the seal element is slidingly arranged within a slot in an axial end (or a radial side) of the seal carrier. The second portion of the seal element is configured to axially (and/or radially) engage the second component.

A sealing apparatus 1 includes a sealing apparatus body 2 and a slinger 3. The sealing apparatus body 2 includes an annular reinforcing ring 10 and an annular elastic body portion 20 formed of an elastic body mounted on the reinforcing ring 10. The slinger 3 includes a flange portion 31 which is an annular portion extending toward an outer peripheral side. The elastic body portion 20 includes an end-face lip 21 which is an annular lip extending toward an inner side and contacts the flange portion 31 from an outer side. At least one groove 33 is formed on an outer side of the flange portion 31 of the slinger 3, on a surface of the end-face lip 21 on an inner peripheral side, a plurality of radial projections 23 are formed side by side in a circumferential direction, and at least one circumferential projection 24 is formed.

A sealing arrangement includes a stationary spindle and a wheel hub rotatably mounted to the spindle. A seal assembly is disposed between the spindle and the wheel hub and includes an outer carrier case having a first cylindrical portion disposed in the inner bore of the wheel hub and a first radial portion extending radially inward from an end of the first cylindrical portion. An inner seal element has an inner metal case having cylindrical portion received on an outer surface of the stationary spindle and includes an annular portion extending radially outwardly from an end of the cylindrical portion and axially spaced from the first radial portion of the outer carrier case. An oil seal lip extends radially outwardly and axially from the annular portion of the inner metal case and engages the first radial portion of the outer carrier case.

A rotary seal arrangement has a rotatably mounted machine part and a machine part that forms a bearing for the rotatably mounted machine part. One of the machine parts forms a seal accommodating structure and the other one of the machine parts has a surface forming a sealing surface. At least one rotary seal is arranged in the seal accommodating structure. The rotary seal seals off a high-pressure area from a low-pressure area between the machine parts.

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.

A seal arrangement includes a first and a second machine part which are arranged spaced apart from one another with the formation of a sealing gap and can be moved relative to one another about a movement axis. A seal element with a base section is arranged on or in a seal holding structure of one of the two machine parts. A sealing head bears in a dynamically sealing manner by way of a sealing section against a sealing surface of the respective other machine part in order to seal a high-pressure side from a low-pressure side. The seal element on the high-pressure side has at least one flow element, wherein during relative movement of the two machine parts fluid on the high-pressure side in the area of the sealing section of flows onto the sealing head.

A spring seal for a joint assembly pivotally joining a lever arm to a machine frame includes an annular body having a W-shaped cross section. The W-shaped cross section includes a first cantilevered arm, a parallel and spaced apart second cantilevered arm, and a spring leg joining the first and second cantilevered arms. The spring seal is disposed between a bearing surface on the lever arm and a lug on the frame. The W-shaped cross section of the spring seal can collapse and relax to accommodate movement between the lever arm and the frame lug. A second spring seal can be disposed between a second bearing surface on the lever arm and a second frame lug opposite the first lug.

A sealing apparatus which seals an annular gap of a hole into which a shaft is to be inserted, includes a sealing apparatus body to be fitted into the hole, and a slinger to be attached to the shaft. The sealing apparatus body includes a reinforcing ring annular around an axis line, and an elastic body portion attached to the reinforcing ring and annular around the axis line. The slinger includes a flange portion extending toward an outer periphery side and annular around the axis line. The elastic body portion includes an end-face lip extending on one side in an axis line direction, contacting the flange portion from another side in the axis line direction, and annular around the axis line. At least one groove is formed on the other side of the flange portion, and a plurality of projections are formed side by side in a circumferential direction on an inner periphery surface of the end-face lip extending in a spiral manner in a rotation direction of the shaft from the other side to the one side and being formed on an inner periphery side of a slinger contact portion of the end-face lip.
