- 摘要：
- The invention relates to a sealing roller bearing, in particular, a ball bearing for support and working roller bearings on roller stands, comprising an axially multi-part outer bearing ring and an axially multipart inner bearing ring and a number of rolling bodies rolling on the running tracks in four rows between the bearing rings. The rolling bodies are retained in each row at an equal separation from each other in the circumferential direction by means of a bearing cage and the bearing chamber, formed between the outer bearing ring and the inner bearing ring, is sealed at both axial ends against the ingress of fluids and dirt by annular seals. According to the invention, each bearing cage of the roller bearing is embodied as a conventional pin cage, comprising a first cage disc, a second cage disc and a number of pins connected to both bearing discs, whereby the annular seals sealing the bearing chamber are embodied as lamellar rings with a sealing connection to the first or the second cage disc of both external bearing cages.
