Swivel-joint roller bearing for e.g. paper machine has guide ring supported on outer bearing ring and formed with transit channels such that recirculating roller series are passed through trajectory spaces relative to bearing axis

摘要

The roller bearing has a cage device (C) to guide the rolling elements (W1,W2), and a guide ring (4) arranged between the fist and second recirculating roller series (R1,R2). The guide ring is radially supported on the outer bearing ring (1) and is formed with several transit channels (5), such that the first and second recirculating roller series are passed through trajectory spaces relative to the bearing axis (X) in the outer bearing ring outside the radial level (NR) of raceway outer edges (K1,K2) of the outer bearing ring lying radial level.
