An aliphatic polyketone compound including 85.0 to 99.5 wt % aliphatic polyketone and 0.5 to 15.0 wt % ultra-high molecular weight polyethylene. An aliphatic polyketone compound described where the ultra-high molecular weight polyethylene is 2.0 to 8.0 wt %. An aliphatic polyketone compound where the ultra-high molecular weight polyethylene has a molecular weight greater than 1.0 million g/mol.

Polyketone compound

A seal having a substantially H-shaped sealing profile.

Seal, method for producing same and sealing arrangement therewith

The present invention provides a sealing ring having at least eight sealing edges. Sealing rings, such as O-ring seals, are generally known. These universal sealing rings can be used for statically or dynamically sealing machine elements. They have the advantage of being suited for a wide variety of possible applications, and of being simple and cost-effective to manufacture.

Sealing ring

A supporting disk for providing bearing support to a rotor of an open-end spinning machine, the supporting disk including a bearing ring and a supporting ring which is made of an elastic polymeric material and mounted on the periphery of the bearing ring. The bearing ring has a side ring on at least one of the sides of its outer edge. The side ring is located at a distance from the outer edge, connected to the bearing ring via holding members, and is also provided with a supporting ring on its periphery.

Supporting disk for providing bearing support to a rotor of an open-ended spinning machine, and method for manufacturing said supporting disk

A supporting disk for providing bearing support to a rotor of an open-end spinning machine includes a hub ring () and a supporting ring () that surrounds the hub ring () at least partially with radial clearance. The hub ring () and the supporting ring () each are made of a polymer material, and the hub ring (), at least on its outer peripheral surface (), has a metal coating () which is located at least partially in the gap () formed by the clearance, and which contiguously adjoins the inner circumferential surface () of the supporting ring (), and extends axially up to at least one of the end faces () of the supporting disk.

Supporting disk

A supporting disk for supporting a rotor, in particular the rotor on an open-end spinning rotor, having a hub ring and a supporting ring situated on the outer circumference of the hub ring, made of a polymer material, and having a running surface for the rotor, wherein the supporting ring ( ) has at least one lip-shaped projection ( ) on at least one of its axial end faces ( ).

Supporting disk for supporting a rotor

A supporting disk for supporting a rotor, in particular the rotor in open-end spinning rotors, having a hub ring and a supporting ring positioned on the outer circumference of the hub ring, having a bearing surface for the rotor, the outer circumference of the hub ring and the inner circumference of the supporting ring being connected to each other with form locking; the supporting ring ( ), in cross-section, being formed from a running part ( ) provided with bearing surface ( ) for the rotor and at least two anchor legs ( ) extending from running part ( ) and directed radially inwardly as well as axially outwardly.

Supporting disk for mounting a rotor

Supporting disk for supporting a rotor of an open-end spinning machine, including a hub ring ( ) and a supporting ring made of polymeric material secured to its outer circumference ( ). The hub ring ( ) is formed as a composite part, and is made of at least two different materials.

A supporting plate for the support of a rotor, in particular of an open-end spinning rotor, having a hub ring and a support ring arranged on the exterior periphery of the hub ring. The support ring has a contact surface for the rotor, the exterior periphery of the hub ring and the interior periphery of the support ring are joined to each other with positive locking. The support ring has a cramp-like shape in cross-section and is formed from a bridge part, provided with the contact surface for the rotor, the bridge part having two lateral clamping anchors emerging from the respective ends of the bridge part and oriented to the inside both radially as well as axially.
