DIN3760 FKM Rotary Shaft Lip Seal
DIN3760 FKM rotary shaft lip seal is a high-performance sealing component designed to prevent leakage of lubricating oils, hydraulic fluids, and other media in rotating equipment. The DIN3760 FKM rotary shaft lip seal is manufactured from fluorocarbon rubber (FKM), providing excellent resistance to high temperatures, oils, fuels, chemicals, and harsh operating environments.
The DIN3760 FKM rotary shaft lip seal is widely used in automotive systems, gearboxes, hydraulic equipment, motors, pumps, industrial machinery, and precision rotating assemblies where reliable shaft sealing and long service life are required.

Product Overview
The DIN3760 FKM rotary shaft lip seal is engineered for dynamic sealing applications involving rotating shafts. Its flexible sealing lip maintains contact with the shaft surface, preventing lubricant leakage while blocking external contaminants from entering the equipment.
FKM material provides superior performance compared with general rubber materials when exposed to elevated temperatures, mineral oils, fuels, and chemical media. The DIN3760 FKM rotary shaft lip seal is suitable for demanding applications where sealing reliability directly affects equipment performance.
The reinforced structure can include a metal case and spring-loaded sealing lip, helping maintain stable sealing pressure during continuous shaft rotation.
