Guide Rings—also known as Wear Rings—are critical components used in hydraulic and pneumatic cylinders to guide the piston and rod, prevent metal-to-metal contact, and absorb side loads. Manufactured using high-performance materials such as filled PTFE, PEEK, and composite thermoplastics, our guide rings are engineered for high wear resistance, low friction, and excellent thermal and chemical stability. These rings are available in split and solid configurations and are custom-machined to match application-specific groove dimensions. With reliable dimensional control and long service life, our guide rings help ensure smooth cylinder operation and extend the lifespan of seals and mating parts.
Prevents piston rod misalignment and metal contact in hydraulic cylinders.
Designed for precise fitment and minimal clearance in grooves.
Reduces wear on seals and improves performance consistency over time.
