The ring can be a seal ring or a thrust ring.

A locking collar is fixed to a stop collar of the spigot.

shaft bearing thrust ring of a valve

A first thrust ring is engaged with the rotatable bushing and a second thrust ring is engaged with the sleeve bearing.

Also provided is a thrust bearing comprising a high-melting-temperature thrust collar (40) and thrust pad (42).

The seal assembly (101, 102) can include a thrust ring (204, 404) and a seal member (202, 402) mounted to the thrust ring (204, 404).

A thrust pad (18) bears and supports a thrust collar (17), which is provided to a crankshaft (2), against a load which acts on the thrust collar (17) in the direction of the rotation axis of the crankshaft (2).

The thrust washer sits atop the castellations of the support structure.

Between the cover and the diaphragm there is a pressure ring (2) which is secured to be integral in rotation with the diaphragm by cams (13) fitted to the latter.

Said outer surface is designed in step form, whereby an axial contact surface is formed, behind which the retaining ring can reach for axial fixation of the retaining ring on the half-shells.

The stop collar is adapted for receiving a liquid gel epoxy adhesive in the annular chamber until the epoxy sets or care to secure the stop collar in place on the casing.

The adjusting washer (8) is mounted between the belleville spring (7) and the stopper ring (2).

The belleville spring (7) is mounted between the spacer pad (6) and the stopper ring (2).

A spring (7) closes the friction clutch (34) through a magnetically non-conductive actuating ring (5) which is securely attached to an armature ring (16).

This seal also provides a thrust bearing washer surface against the camshaft.
