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. |
Typical application:
Guide rings
Bearings, Shaft sleeves, Bearing Bushes
Shipbuilding, Marine Components
Engineering Machinery Components
Hydroelectric Power Components
