Based on the above flowcharts, the oil seal type that meets the requirements shown in Table 3 would be the type code MHSA or HMSA shown in Table 4.
Material: There are several material options. Nitrile (Blank), Viton (V), Silicone (S), EPDM (E), Carboxylated Nitrile (X), HNBR (H), Polyacrylate (P), and Teflon (T).
Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
