PFC-20 Synthetic Fiber Polyester Resin Guide bands

Wear rings prevent metallic contact between pistons and cylinders or rods and glands where forces act perpendicular to the direction of movement.

PFC-20 Material Structure:

Polyester resin + synthetic fiber

PFC-20 is composed of synthetic fiber, reinforced polyester resin and self-lubricating micro powders. PFC-20 features in low friction, high mechanical property, good corrosive resistance and low water absorption.

Wear Cut Styles:

Advantages
Angle cut rings improve bearing stress at the gap. These rings tend to suit reciprocating movement.
Straight Cut, also known as Butt Cut rings are the easiest style to install in many applications. Straight cut rings are best suited for rotary movement.
Step cut rings also improve bearing stress at the gap. However, they offer better resistance to contaminants and spike loads. This type of design offers the best level of performance.
