Polyester Resin Guide Strip / Tape
Polyester Resin Guide Strips are high-performance guiding elements specifically engineered for hydraulic seals and pneumatic cylinders. Installed on pistons or rod ends, they serve to absorb lateral forces, prevent metal-to-metal contact, and ensure precise axial movement. Manufactured from durable polyester resin composite, these guide strips exhibit excellent wear resistance, dimensional stability, and thermal endurance, making them ideal for demanding applications.
