Верхний подшипник скольжения рычага Caterpillar 6554216

An Upper Arm Sleeve Bearing allows controlled movement and rotation of upper arm components by providing a low-friction interface. It reduces metal-to-metal contact and helps absorb radial forces that occur during operation. Maintaining alignment and reducing operational resistance helps equipment move more efficiently and reliably. The part also improves handling stability and protects adjoining surfaces from damage caused by continuous motion.Attributes:• Ensures stable pivot movement in upper arm joints.• Provides a low-friction surface for smooth rotation.• Helps maintain alignment during joint movement.• Supports load distribution through the joint assembly.Applications: An Upper Arm Sleeve Bearing is located within the pivot joint of the upper arm assembly, enabling smooth rotation and maintaining alignment during movement.
