摘要： The invention relates to a sealing device for roller bearings, comprising a journal seal (4), which is arranged upstream on the roller-ball side of the annular seal (8) which is connected in a rigid manner to an annular projection (7) of the bearing housing (5). The sealing lip (18) of the sealing device is applied to the front side (10) of the roller (1) by means of a sealing contact. The aim of the invention is to improve the sealing device in such a manner that the sealing lip of the annular seal is barely impinged upon by cooling means mixed by impurities, making it long lasting and ensuring that no undesired water can penetrate into said outlet. According to the invention, an L-shaped profile (11), in the cross-section, is rigidly connected to the first side (12) thereof by means of the front side (14) of the roller (1), such that the sealing lip (18) is applied to areas of the first side (12); such that the second side (13) of the L-shaped annular profile (11) is sealed to the roller balls at a certain distance from the annular seal (8) and regions of the annular projection (7); and such that the annular projection (7) comprises an outlet groove (9) which is arranged on the outer side and is open towards the outside.

摘要： A bearing has a mount relative to which can move a part to which hydraulic fluid must be supplied. A connector has a housing fixed to the bearing mount and formed with a central bore centered on an axis and with a radial bore extending outward from the central bore. A tube axially shiftable in the central bore forms at the radial bore an annular compartment and has a passage opening radially into the compartment and axially at one end of the tube. A conduit is connected a coupling at one end of the tube and the part. Another coupling at an outer end of the radial bore connects to a source of hydraulic fluid under pressure so that the fluid can flow through the radial bore, annular compartment, and passage to the coupling at the one end of the tube and then through the conduit to the movable bearing part.
