Sealing bearing arrangement with convex bushing ring

摘要

A self-aligning bearing arrangement has a compressible packing (20) for forming a gas-tight seal between the outer housing (2) and a rotatable shaft (10). A bushing ring (22) supports the shaft (10) and accommodates any misalignment thereof by having an inner surface (26) of convex cross section. The bushing ring (22) is urged axially against the packing (20) by a drive plate (28) and urging means (30, 32).
