Sealing rings / Guide bands
OLYMPUS DIGITAL CAMERA
Mainly used for “oil-free” compressors and sectors in which it is necessary to produce “clean” compressed air without lubrication.
The rings and the guide bands are used to maintain perfect coaxiality between stem and cylinder, avoiding problems during linear movements or piston rotation. Usually mounted on tailored seats, they can be manufactured according to customer designs using the most common materials for these products, chosen subject to the kind of lubricants eventually used and other application data.
The most common materials are:
- FLON-CHEM 1040: PTFE + 40% bronze;
- FLON-CHEM 1060: PTFE + 60% bronze;
- FLON-CHEM 1040M: PTFE + 40% bronze + Mos2;
- FLON-CHEM 1001M: PTFE + 25% glass + Mos2;
- FLON-CHEM 1002: PTFE + 25% Carbographite;
- FLON-CHEM 1000: Virgin PTFE;
- FLON-CHEM 1002: PTFE + 25% carbographite
- FLON-CHEM 1100J: PTFE + polyimide
- FLON-CHEM 1009: PTFE + aromatic polyester
- PE 1000 UHMW;
- POM-C
FF.GI Srl can also offer technical advice based on the compressor type or the chamber material/coating. Guide bands can be manufactured from both tubes and tape. The sealing rings are made with a special machine that can cut everything in one procedure, granting maximum quality, precision, and finishing accuracy. The cut can also be made according to customer requirements.
