传送带链

精密传送带链，就像传动链一样，由一系列轴承组成，通过约束链板相互间保持精确的关系。

     Each bearing consists of a bearing pin and bush on which the chain roller revolves. The bearing pin and bush are case-hardened to allow articulation under high pressures, and to contend with the load carrying pressure and gearing action imparted via the chain rollers.
