Our main objective is to continuously exceed our customer’s expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Laminated felt seals are made by combining grades of felt with layers of impervious elastomer. This sandwich construction permits use of two or more felt grades or densities in one seal; one grade for oil retention and a second for dust exclusion. The impervious layers of oil-resistant elastomer also stop leakage of low-viscosity liquids through the felt. Ball mill machines – if you are a mining industry expert, you are probably familiar with ball mill machines. It uses felt seals in trunnion sealing. You may also find seals holding batter doors, valves, and pumps. Resilience – if you choose high-quality wool felt, you will be surprised by how effective it is in withstanding severe weather conditions. Whether it is constant pressure, wear, and there, or harsh environmental factors, these seals can continue delivering continuous results. Plain felt seals are precision-cut washers fabricated from standard grades of felt. They are usually presaturated with lubricants of slightly greater viscosity than that used in the bearing. Plain felt seals afford positive bearing protection and provide a reservoir for lubricant storage -- making it available as needed. If run dry, they protect and polish rather than score a shaft. They seldom fail through aging, embrittlement, or disintegration. At temperatures from -60 to 250°F and operating speeds up to 2,000 fpm, plain felt seals are highly economical and require replacement only when the machines in which they are used are overhauled. These seals should not be used with oils of extremely low viscosity or to retain pressurized lubricants. For these applications, laminated or impregnated felt should be considered.

Low friction: The coefficient of friction averages 0.22 for dry felt against steel and is substantially reduced when felt is presaturated with oil. This felt is similar to S.A.E. F-5 in quality, but recommended for uses where abrasion and wear are not important factors. These felts are often used for grease and oil retention, fluid storage and delivery, dust shields operating under less severe conditions, as well as for plug filters for gas and air.

Low Density Woolen Felt

Temperature limit: The usual temperature limits of felt seals are -60 to 250°F. However, synthetic-fiber felts offer a wide range of strength and chemical resistance at temperatures up to 400°F. Felt gaskets | Felt seals | Felt strips J A Harrison – the leading supplier of felt gaskets, felt seals and felt rings Felt processed parts The felt seal is pressed fiber to prevent leakages or connect two items. We mostly use wool to make these seals, although synthetic textiles can be an alternative. It is a type of mechanical sealused in many industries. These strips exhibit exceptional resistance to wear, abrasion, and moisture, making them ideal for long-term use. Their superior texture and density ensure effective insulation, sound dampening, and surface protection.

Shaft speed – the experts suggest that you shouldn’t use these seals in environments where the FPM is higher than 2,000. You can design smooth and hard shafts, and use generous seal lubrication to make them accommodate 4,000FPM, but that is only for extreme application.We are able to offer additional treatments to the majority of our wool felts (subject to minimum quantities), these include:
