Cat® Stick Arm is a structure component used to tilt and lift the attachments. Cat® Stick Arm must endure high loads and frequent direction and position changes. Cat® Arms are designed and manufactured to meet these types of demands. They transmit motion from the boom to the attachments with the help of sleeve bearings. On the whole, six sleeve bearings are used in the stick arm. Cat® Sleeve Bearings are built with high grade steel and hardened for exceptional strength and wear life. They work as a system for your specific Cat® machine and are tested and proven in the world's most severe applications. They give you maximum strength and resistance and result in a lower overall cost, outstanding strength and fatigue life, superior resistance to abrasive wear and exceptional protection against pin spalling and galling, even in high-load conditions.Application:Cat® Stick Arm is used to transmit swing motion to the attachments, used in Cat® machines.
