摘要
The cross link (15) has journals. Each journal has an end surface, a cylindrical bearing surface and at least one adjoining sealing surface (23), and seating part (24). Each journal has a bearing bush (9) with a tubular cylindrical casing with inner surface, a base covering the end surface, and an open end (25) with a contact surface (28). Rollers or needles are (22) positioned in the annular gap coaxially around the journal. Each bearing bush has an annular main seal (26) and at least one sealing lip (29,30) and an annular preliminary seal (27) on the seating part of the journal, and a sealing lip (47). The preliminary seal has spaced apart grooves (40). The main seal has an annular support (31) protruding from the open end of the bearing bush, and has an outward pointing collar (34). The preliminary seal has a holder ridge (48) and or a second sealing lip.
