PFC-22 Synthetic Fiber Polyester Resin Wear rings

Wear/guide Rings have the task of guiding the rods and pistons of hydraulic cylinders preventing direct metallic contact with the cylinder housing. They must have the capacity to absorb strong transverse forces even over a short guide distance while keeping frictional losses low. Kintowe can offer the right Guide Ring for every type of cylinder, with maximum reliability and longevity.

PFC-22 Material Structure: 

Polyester resin + synthetic fiber

PFC-22 is composed of specialty synthetic fiber, reinforced polyester resin and solid lubricants and other ingredients. PFC-22 has superior wear resistance and almost no water swell; compares to metallic material, good elastic deformation allows it operating well under high loading. It is ideal for underwater operation (even in sea water) and offers maintenance-free solutions for special equipments.

Wear Cut Styles:

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, Shaft Sleeves

Stern Tube Bearings, Rudder Bearings

Main Hatch Bearings, Hatch Cover Pads

Cargo Pump Bearings, Propeller Bearings

Sheave Bearings, Deck Machinery Bearings

Mooring System Bearings, Offshore Platform Bearings
