Wear rings, or guide rings, support pistons and rods, preventing metal-to-metal contact. They absorb radial loads, reducing wear on seals and cylinder walls. Materials like PTFE, bronze-filled PTFE, or fabric-reinforced phenolics are common. Proper clearance and material selection minimize friction and extend component life. Wear rings are often overlooked but critical for maintaining... https://globalsealstech.com/hydraulic-seals/
