Crescent bearing

The crescent bearing is a kind of swing dedicated bearing with special products, and its production process is extremely complex. It uses SKF3 high-purity bearing steel, which has undergone precision forging, and the workpiece adopts the most advanced salt bath bainite heat treatment in the world. In order to effectively release stress, the workpiece after heat treatment needs to undergo ultra-low-temperature freezing at minus 80 degrees, and the workpiece needs to be stored for two to three years before grinding and processing can be carried out. It is mainly applied in production fields such as metallurgy, mining, and engineering machinery, and its service life has exceeded the advanced level of world famous brand products.

The crescent bearing is a half-moon shaped bearing used on 145/190 hydraulic pumps, and is suitable for the swing parts of various imported reduction gears for engineering machinery. It can effectively extend the service life of the hydraulic pump bearing and fully meet the index requirements of the main engine.

The crescent bearing is a component that connects the swash plate and the pump body, because the swash plate needs to swing along the arc of the crescent bearing (roughly plus or minus 20 degrees), so that the displacement of the plunger pump can be controlled. When the swash plate is flat, the displacement is 0, and when the swash plate reaches the most tilted position, the displacement is the largest. The function of the crescent bearing is to reduce the friction coefficient between the swash plate and the pump body and to ensure smooth rotation.
