Подшипник скольжения, внутренний диаметр 70,23 мм Caterpillar 1607864

The Sleeve Bearing, also known as a plain bearing, provides support and reduces friction between a rotating pin and the thumb link assembly. It consists of a cylindrical metal sleeve that fits with the pivot pin and the mounting surface in the idler link. The inner surface of the sleeve bearing is lined with a low-friction and self-lubricating material.Attributes:• Hardened to withstand the high level of shear force without deformation• Provided with a lubrication hole for better circulation of the lubricantsApplications:The Sleeve Bearing is used in the thumb to reduce friction and wear between the rotating pin and the idler link that are in relative motion with each other, allowing for smooth linkage.
