150201020088B001 Oil seal skeleton Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core model of high-end oil seal skeletons, Sany 150201020088B001 boasts four major advantages: “sealing, wear resistance, stability, and compatibility.” It is widely used in heavy equipment such as cranes, injection molding machines, marine anchor winches, and mining machinery, playing a crucial role in sealing and protection. It provides stable support for the oil seal, maintains its shape and tension, ensures radial tightness of the sealing lip, blocks hydraulic oil and lubricating oil leakage, prevents dust and impurities from entering, protects the core components of the equipment, is compatible with various machine models, and is easy to install and can be put into use directly.
Compared to ordinary oil seal skeletons, this product is manufactured to Sany’s original standards, strictly adhering to the quality control system for industrial sealing components. The skeleton is made of high-quality cold-rolled steel sheet, stamped and formed, with a galvanized surface for corrosion protection. It is paired with an oil-resistant fluororubber sealing lip, and undergoes precision machining and sealing testing. It exhibits excellent impact resistance, wear resistance, and high and low temperature resistance, effectively solving problems such as seal failure and skeleton deformation, reducing maintenance costs, and extending the service life of oil seals and equipment. Its optimized inner-enclosed structure completely encapsulates the metal skeleton in rubber, combining elasticity and rigidity. The sealing lip is equipped with a self-tightening helical spring to compensate for self-tightening force, ensuring reliable dynamic and static sealing. It is suitable for complex working conditions such as high pressure, high and low temperatures, and high dust, meeting the core requirements of industrial equipment.
