摘要:
A seal assembly for sealing a space between a housing and a component against a liquid medium includes a seal element fixedly connectable to the housing, the seal element including a seal lip that is movable at least in a radial direction, the seal lip being disposed at an angle with respect to the radial direction and a support element in abutment with the seal lip. The support element and the seal element are configured such that a pressure exerted on the seal lip by the liquid medium is transmittable in the radial direction to the support element, and the seal assembly also includes a further seal assembly on a side of the support element axially opposite the seal element, the further seal assembly including a first seal having a first seal body and a second seal having a second seal body.
摘要:
A sealing device for a bearing unit, where the unit has a radially outer ring, two rows of rolling bodies arranged, respectively, between the radially outer ring and a pair of radially inner rings. The sealing device further provides a spacer including an annular groove and configured to be arranged between the radially inner rings of the bearing unit and a seal housed inside the groove of the spacer. The seal is “U” shaped, defines a volume internally and is configured to be mounted in the annular groove with the concavity directed towards the axis of symmetry of the bearing unit.

A friction device for a bearing assembly includes an annular friction module defining a friction surface that extends around a revolution axis of the friction device and that is configured to lie against and to exert a friction torque on a cylindrical surface rotating with respect to the friction device, the friction surface being cylindrical before the friction device is mounted around the rotating cylindrical surface.
