Claims

7. Bearing bearing (1) according to claim 6, wherein each segment (62) comprises only an axial hole (58) positioned at the center of the circumferential length of said segments (62).

8. Bearing bearing (1) according to claim 6, wherein each segment (62) comprises at least two axial holes (58), each axial hole (58) being positioned regularly along the circumferential length of each segment (62).

9. Bearing housing (1) according to any of the preceding claims 1 to 8, comprising at least three seals (38, 40, 42) and two spacer rings (52) spaced apart from each other by one of the seals (38, 40, 42) which is axially interposed.
