BIDIRECTIONAL-LIMITING BRIDGE BEARING

摘要

A bidirectional-limiting bridge bearing, comprising an outer race (1, 4), an inner race (5) and a rolling member (2). The outer race (1, 4) and the inner race (5) fit with each other. The outer race (1, 4) has a rolling groove (7) disposed on a side surface thereof contacting the inner race (5). The inner race (5) has a boss (3) disposed on a side surface thereof contacting the outer race (1, 4). The boss (3) is in the middle of the rolling groove (7). Two side surfaces of the boss (3) respectively surround an empty cavity with a corresponding inner side surface of the rolling groove (7). The rolling member (2) is disposed in the empty cavity. Rolling balls are used as the rolling member, thereby achieving a bidirectional limiting effect. The bearing inner race (5) and the bearing outer race (1, 4) may have aligned or non-aligned contact surfaces, so that the bearing may fit with other components in multiple manners.
