188-4217 150.05 mm Bore Wear Ring Piston Guide Rod
Cat® Plastic Wear Ring Piston Guide for Hydraulic Cylinders
Description
Cat wear rings guide the hydraulic piston or rod to maintain alignment and prevent metal-to-metal contact, reducing wear and distributing pressure evenly across the seals.
Applications
Used as needed for servicing hydraulic cylinder components to ensure leak-free equipment. Refer to your Operation and Maintenance Manual or contact MECHSC for more information.
