PTFE Piston Guide Rings & Piston ring
PTFE Piston Guide Rings & Piston ring
For preventing metal-to-metal contact between piston and cylinder during sliding (particularly in case of lateral forces), PTFE guide ring is simple assembly and wear-resistant. Thanks for its good media resistance, the piston guide ring can be used in several media ranging from mineral oil-based hydraulic liquids, environment-friendly hydraulic liquids and water-oil emulsions to flame-resistant hydraulic liquids and dry-running applications. Piston guide rings offer very good gliding behavior, good emergency running properties and also a high wear resistance. Additionally, they help to attenuate mechanical vibrations. For an efficient seal, our piston rings provide a consistent and tight radial fit between the cylinder wall and the piston ring's running surface. The radial fit is produced by the piston ring's inherent pressure. The piston ring is also designed to keep the piston ring lands sealed. Cylinder wall contact pressure is another piston ring style that we provide. The flexibility of the piston ring material, the free piston ring gap, and exposure to combustion gases all influence this pressure. Commonly use in the industries of: Compressors operating Gas rotary pumps Liquid gas and vacuum pumps Rotary compressors Food processing Pneumatic hammer drills Automotive Moreover, at DCW, we design and manufacture various of products in high performance fluoropolymer material, such as PTFE, modified PTFE, PTFE compound, PEEK, PFA, PCTFE and PVDF, deliver reliable and stable quality for our clients. When it comes to raw material, we only work with the best suppliers such as Shandong Dongyue Polymer, POLYFLON , Dyneon, because the quality is always the heart and everything we did. All the products are manufactured to order, so you can get exactly what you need.
