Polypac Cylinder Guide Ring

Polypac Cylinder Guide Ring — Reliable Guidance for Hydraulic Cylinders

Polypac Cylinder Guide Rings are engineered to keep piston and rod movement smooth, stable and wear-free. Designed for hydraulic cylinders in industrial, mobile and offshore equipment, these guide rings reduce metal-to-metal contact, prevent scoring and extend seal life. Built from advanced materials and produced with strict quality control, they perform reliably in both standard and harsh environments.

Why choose Polypac Guide Rings?

Polypac combines decades of sealing expertise and modern manufacturing to deliver guide rings that stand out:

• Low friction: Filled PTFE and engineered polymers lower stick-slip and improve efficiency.
• High wear resistance: Bronze-, carbon- or glass-filled compounds resist abrasion and retain shape under load.
• Dimensional stability: Precise molding ensures tight tolerances and consistent guidance.
• Custom solutions: We tailor designs and materials for special working conditions.

Materials and applications

Our experience began with filled PTFE formulations, and today we offer guide rings in a broad range of materials for optimal performance:

• Bronze-filled, carbon-filled, graphite-filled, MoS2-filled and glass-filled PTFE for high wear and low friction.
• Elastomer-backed options for improved damping and assembly fit.
  Applications include hydraulic cylinders for construction machinery, presses, agriculture, material handling and marine equipment.

Manufacturing strength and quality assurance

Polypac’s custom rubber ring and O-ring factory spans over 10,000 m2 with 8,000 m2 of production space and advanced testing equipment. Founded in 2008, we have grown into one of China’s largest seal developers, collaborating with universities and research centers to refine materials and processes. Every guide ring undergoes dimensional, hardness and wear testing to meet demanding performance standards.
