Twin-row bearings support shaft within housing, housing support ring

摘要

A twin-row bearing supports a shaft (2) within a housing, and has two adjacent axially concentric bearings, or two radially concentric bearings arranged inside each other. The bearing has a housing support ring (3) or a shaft support ring (4). The housing support ring or the shaft support ring form the roller path for both the first and second bearings. The roller path for the first bearing is an outer path, while that of the second bearing is an outer or an inner path. The roller bearings are either of identical size or different (7,18). One bearing (8) is a needle bearing. One bearing (17) is a slip bearing. The housing support ring or the shaft support ring (4,16) are fabricated by a non-cutting method.
