Product Advantages:
The inner wall of the bushing is evenly distributed with blind holes with conical cross-section.
The lubricating oil wedge is formed naturally during the grinding process of the inner hole of the bushing
The oil storage capacity of oil pocket is large, which is 3~5 times of that of ordinary oil tank and can be free from maintenance for a long time.
The oil pockets are evenly distributed on the inner wall, and the center distance of the oil pockets in the circumferential direction is fixed. No matter how large the bushing is, it only needs a small rotation angle to fill the inner surface of the bushing with the oil cloth,without lubrication dead area.
The oil pockets evenly distributed in the inner holes do not damage the bearing capacity of the inner wall of the bushing and prolong the service life of the bushing.
Material:20CrMnTi,20CrMo and other low carbon alloy steels
Surface treatment: Molybdenum disulfide spraying
