A Wear Ring is also known as a wear sleeve or wear band. Its primary function is to minimize wear and tear on the rotating and stationary parts of the boom cylinder, reduce leakage, maintain efficiency, and prevent metal-to-metal contact between the moving parts.

Attributes:
• Helps to absorb the impact and vibrations caused by the movements
• Ensures the proper sealing function

Applications:
A Wear Ring is used to minimize the clearance between the pump actuator and its other supporting components within the boom cylinder and create a tighter sealing connection.
