Piston pings and guiding pings are made by filled PTFE material to achieve the oilless lubrication between cylinders and pistons.
The piston pings and guiding pings are made by non-metal self-lubricating materials to achieve the oilless lubrication between cylinders and pistons.
Filled polytetrafluoroethylene material (Filled PTFE) is selected to make them in series product because of its widest and ripest application at present.
The property tests and customer use indicates that selected friction materials and structure parameters are reasonable, sealling effect of seal rings is fine, properties of series products are advanced, samples can run smoothly and reliably, their noise is low.
