The connecting rod bearing is generally used in bulk, rod bushing is generally used in the middle part of the connecting rod bearing head connecting rod bushing connecting rod and crankshaft is connected to the piston pin and connected in the middle part of high speed engine, connecting rod bearing need coating, generally without coating. The connecting rod bearing generally no oil tank, oil hole, and the connecting rod bushing generally has oil groove or oil bearing and sliding bearing bushing belongs to the category of connecting rod bearing connecting rod bearing rod bushing is matched with a pin connection, to reduce the wear of the crank pin connecting rod bearings.

The connecting rod bearings for sliding bearing partition. End bearing of crosshead rod is often made by oneself, and the connecting rod bolt and the rod body are fixedly connected, and often on the inner surface of direct casting antifriction alloy. End bearing without crosshead rod, the upper part and the rod body are made into a whole, and the lower part of the bearing cover is made separately, and then the connecting rod

The upper part of the bearing is fixedly connected with the upper part, and the inner surface of the upper part of the bearing and the lower half is provided with a bearing bush. In order to lubrication, in the end bearing of drilling a hole, and the antifriction alloy on the surface of oil tank and open garbage tank etc.
