Product Name: Hydraulic Cylinder Piston Seal Rubber Parts Model NO.: SPGO Standard: Standard Shape: O-Ring Performance: High Pressure Type: Oil Seal Application: Cylinder Material: PTFE+NBR Ring Size: Many Color: Customized Trademark: HTong Transport Package: Wooden Box and Carton Specification: many Origin: Hebei HS Code: 4016991090 Product Description Performance and use:Constructed of awear-resistant, filled PTFE ring and O-ring. The O-ring provides apre-tightening force to compensate for the wear of PTFE square rings. Suitable for hydraulic cylinder piston seal, two-way seal. General and supporting the use of guide ring. Pore size less than 40 specifications, should be used split groove.Material:PTFE +NBR, under special circumstances using rubber fluorine rubber FKM.Working conditions:Working pressure: 0-40MPa;Reciprocation speed:≤5m /s;Operating temperature: O-ring for the glue NBR: -30 ~+120 ºC, fluorine rubber FKM: -20 ~+200 ºC;Working medium:hydraulic oil, gas, water (in the phosphate ester hydraulic oil use fluoride rubber).design standards:This series conforms to the ISO 7425/1 standard, complies with GB /T15242.1-94 and GB /T15242.3-94 standards, reference to Trelleborg GS55044 series, Merkel OMK-MR series and Parker OE series.STD seals: acombination of rubber O-ring and polytetrafluoroethylene ring. O-ring force, grid to circle for the double acting piston seal. Low friction, no crawling, small start force, high pressure. The lattice ring is usually composed of asynthetic rubbery ○-shaped seal and apolytetrafluoroethylene-filled square seal, which can be divided into holes for the ring and the ring, but the seal The role is the same, according to its own deformation on the sealing surface to produce ahigher initial contact stress, to prevent leakage of non-pressure liquid. When the hydraulic cylinder is operated, the pressure liquid is extruded through the square seal through the elastic deformation of the ○-shaped seal to close the sealing surface to produce ahigher additional contact stress with increased pressure of the pressurized liquid and Together with the initial contact stress together to prevent leakage of the pressure liquid.A rod, shaft, and swivel, used for rotation or swinging. It is atwo-way pressure or by the role of pressure acting two-way rotating ring. It consists of acombination of adynamic seal ring and astatic O-ring. Seal ring The outer ring seal is specially designed to accommodate high pressure and low speed conditions. One or two annular grooves on the sealing surface can increase the specific pressure of the sealing surface, thus also improving the sealing effect, the groove forming the lubricating oil Cavity, but also reduces the friction, which has agood operational.Technical data: working pressure: 30PMa, working temperature: -30 ºC ~+120 ºC (O-ring material for the Dingqing rubber 70), -20 ºC ~+205 ºC (O-ring material for the fluorine rubber 80), the peripheral speed :To 5m /s, working medium: mineral oil hydraulic oil and flame retardant hydraulic oil. Material: Seal ring ------ Polytetrafluoroethylene /carbon compound D32, O-ring ----- Dingqing rubber 70 or fluorine rubber.We can design and manufacture various rubber parts, custom-made is welcomematerial: NBR, FKM, EPDM, silicon rubber are available.size: hundredscustom-made is welcome.Welcome to contact anytimeterialNBR, FKM, ,VMQ ,HardnessShore 70-90 or according to orderMOQ100 PCSSampleFree,ColorsBlack, brown, red, white, black, green, blue,SizeOD can be 12mm to 2000 mmPacking10 or 20 pcs/paper, then in cartonProduction Time10-15 daysOEMAcceptableMold chargefreeTel: 0086 15933828740
