High Quality Red Colour Silicone Fabric Reinforced Rolling Rubber Diaphragms

Product DescriptionRolling Rubber DiaphragmsRolling rubber diaphragms are special diaphragms shaped like top hats which provide the properties both of bellows and diaphragms. The rolling diaphragms have deep folding parts, which allow smooth rolling action. A long stroke is possible, and the effective pressure receiving area will be maintained the same throughout the operation.Because the Rolling Rubber Diaphragm will move with a rolling action, it will not be necessary to pay special attention to the surface finish, materials, and hardness of the piston and the cylinder. In addition, these rolling rubber diaphragms can respond to minute pressure variations, greatly contributing to improving the performance of equipment in the air pressure and liquid pressure control fields. The design of the rolling rubber diaphragms enables their use without any lubrication. The rolling action of this type of diaphragms allows no friction loss in addition to extremely small hysteresis loss. MaterialHardness  (Shore A)TemperatureStandard SizeAvailableNBR(Buna, Nitrile)FKM(FPM)EPDM Silicone(VMQ)HNBR FFKM(FFKM, Kalrez)60~90 70~90 60~90 40~70 60~90 70~90 -40ºC-110ºC  -20ºC-220ºC  -45ºC-150ºC  -55ºC-204ºC  -48ºC-180ºC-18ºC-326ºCAS-568(USA)JIS-B2401(Japan)DIN-3771(Germany)BS-1516(UK)ISO3601(International)R(France)ID≤2000mm     CS≤40mmResistanceColorCertificateApplication Hydraulic Fluid  Engine OilChemical  Ozone & UV Steam & Hot Water  Low Temperature  High TemperatureBlack  Brown  Red  GreenWhiteBlue  ClearCustomizedISO9001SGSRoHSREACHAuto Industry  Construction Machinery  Machine Tool Equipment  Food Health  Water Treatment Chemical Processing  Hydraulic Pneumatic  Industrial Manufacturing   Detailed Photos     Company ProfileWe Tianjin SWKS is a manufacturer of rubber products and plastic parts with many year experience in China.
