Product Details

Products:PFC-5 hydraulic wear rings

This type hydraulic wear ring is composed of high quality cotton fabric, soluble phenolic resin and MoS2 and processed under certain temperature and pressure. It can guide the rod or the piston and prevent matallic contact with the cylinder when radial forces act prependicular to the direction of movement.


Material structure: phenolic resin+ cotton fabric +MoS2


Typical Application:

Engineering machinery guide rings, bushings, shaft sleeves

Water conservancy machinery bearings

Hydraulic machinery, forging machinery tool guide bushings

Marine bearings
