Product Description Product DescriptionOil seals are also referred to as rotary shaft seals. They are commonly used to seal grease, liquids, or dirt. The oil seal is an essential component of any rotating and moving assembly, stabilizing the space between stationary and moving parts in mechanical equipment. Typically, an oil seal consists of three fundamental elements:A sealing material (rubber component), metal casings, and springs. It is a versatile sealing assembly.Types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others.We offer a diverse selection of rubber materials for the manufacturing of oil seals, ensuring suitability for various operating conditions. These high-performance rubber materials can endure a range of chemicals and extreme temperatures, whether high or low.

During the installation process, ensure that the oil seal is perpendicular to the shaft center to prevent tilting, and apply an appropriate amount of lubricating grease at the lip to reduce dry friction.Company ProfileOur AdvantagesFAQ
