Various lip materials are also available to best suit design challenges such as temperature and chemical resistance, while material options range from nitrile for low-temperature applications to Viton® for high-temperature and low-compression operations. Common lip materials available for use in our metric oil seals include: Nitrile — A low-cost option, nitrile has superior low-temperature capability and abrasion resistance, as well as low swell in hydrocarbon fluids. It has poor heat resistance, however, and is not resistant to ozone or lubricants containing sulphur or EP additives or hydrocarbons/oxygenate blends. Temperature range: -40° F to 225° F / -40° C to 107° C) Polyacrylate — Unlike nitrile, this higher-cost material has high resistance to EP lubricants and higher heat capabilities. It also features low swell in hydrocarbon fluids. Polyacrylate has limited to low temperature capability and poor dry running capability. It’s also subject to attack in aqueous media. Temperature range: -20° F to 300° F / -29° C to 49° C) Silicone — Good dry-heat resistance, excellent low-temperature capability, and good ozone resistance make silicone an ideal, relatively affordable lip material for many applications. It can, however, be easily damaged during installation, and has poor resistance to some EP additives and oxidized oil. Silicone also has a high swell and poor dry running performance. Temperature range: -80° F to 350° F / -62° C to 176° C) Fluoro-elastomer — Although relatively expensive, long-lasting fluoro-elastomer has excellent high-temperature capabilities and is compatible with many types of fluids. It does have poor resistance to basic fluids, and is prone to attack by high-performance gear lubes. Temperature range: -30° F to 400° F / -35° C to 204° C) Depending on your application, you may need to employ premium lip materials, such as: Ethylene-acrylic (Varmac®) — This intermediate-cost material has higher heat capabilities than both nitrile and polyacrylate, and also has a better low-temperature performance than polyacrylate. It has good abrasion and dry running capabilities. However, it has high swell in hydrocarbon fluids and limited capability in high-frequency applications or following eccentric shafts. Temperature range: -30° F to 325° F / -34° C to 163° C)Tetrafluoro-ethylene propylene (Aflas®) — More expensive than fluoro-elastomers, this material has better chemical resistance to all hydrocarbon fluids, acids, bases, and oxidizing agents. It can perform in the complete range of hydraulic fluids and has continuous heat resistance over 400° F. As for its weaknesses, tetrafluoro-ethylene propylene has poor chemical resistance to hydrocarbon-oxygenate blends and poor low-temperature capabilities. Temperature range: -30° F to 400° F / -34° C to 204° C) Available Dimensions: Shaft Diameter (d): 6 mm to 400 mm Outer Diameter (D): 16 mm to 440 mm Width (b): 4 mm to 95 mm Results Per Page : 25 50 100 200 Results 76 - 100 of 408 Unit of Measure: Metric 1 2 3 4 5 » Item # (d) Shaft Diameter (D) Outer Diameter (b) Width MS18X35X7 18 mm 35 mm 7 mm MS18X36X7 18 mm 36 mm 7 mm MS18X38X7 18 mm 38 mm 7 mm MS18X40X7 18 mm 40 mm 7 mm MS19X27X6 19 mm 27 mm 6 mm MS19X30X7 19 mm 30 mm 7 mm MS19X32X8 19 mm 32 mm 8 mm MS19X37X7 19 mm 37 mm 7 mm MS19X38X7 19 mm 38 mm 7 mm MS19X40X10 19 mm 40 mm 10 mm MS19X47X7 19 mm 47 mm 7 mm MS20X30X5 20 mm 30 mm 5 mm MS20X30X7 20 mm 30 mm 7 mm MS20X31X7 20 mm 31 mm 7 mm MS20X32X7 20 mm 32 mm 7 mm MS20X35X7 20 mm 35 mm 7 mm MS20X36X7 20 mm 36 mm 7 mm MS20X37X7 20 mm 37 mm 7 mm MS20X37X8 20 mm 37 mm 8 mm MS20X40X7 20 mm 40 mm 7 mm MS20X40X7 20 mm 40 mm 7 mm MS20X42X7 20 mm 42 mm 7 mm MS20X42X10 20 mm 42 mm 10 mm MS20X46X7 20 mm 46 mm 7 mm MS20X47X7 20 mm 47 mm 7 mm Results 76 - 100 of 408 1 2 3 4 5 »
