PFC-7 Ultra Strong Special Fiber Phenolic Wear rings

Phenolic guide/ wear rings provide a bearing surface to center the piston and rod dynamic surfaces in a reciprocating cylinder application. It can prevent metal-to metal contact and improves seal life performance.

PFC-7 Material Structure:

 Phenolic resin + strong special fiber

PFC-7 is based on modified phenolic resin reinforced with ultra strong special fiber, added with solid lubricants, processed under certain temperature and pressure. Compare to other fiber-reinforced(cotton fiber, polyester fiber, polyamide fiber and so on) phenolic products, PFC-7 has excellent compressive strength, it can adapt to the complex working conditions.

PFC-7 Material Advantages:

Excellent compressive, tensile, fire, heat and chemical corrosion resistant property

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 ring

Back-up ring for mine, coal machinery and equipment

Spare parts for shipbuilding, marine machinery

Spare parts for water conservancy wind power equipment

Spare parts for mooring system, offshore platform
