Product introduction:
1.Skeleton Support:A stamped thin steel plate component is embedded inside to act as a rigid skeleton. This maintains the oil seal's overall shape and prevents deformation during installation and operation.
2.Auxiliary Functional Layer:The sealing lip is coated with Polytetrafluoroethylene (PTFE) and equipped with a garter spring. This design enhances sealing pressure and improves conformity to the shaft journal, effectively reducing the risk of oil leakage.

Advantages of Crankshaft Seal:
1.Superior resistance to harsh engine internal working conditions
The main sealing layer is made of Acrylic Rubber (ACM), which is specially formulated to withstand the high temperature, oil corrosion and high pressure inside the engine. It boasts excellent anti-aging and wear-resistant performance, maintaining stable sealing properties during long-term continuous operation and adapting to the extreme working environment of the engine compartment without premature performance degradation.
2.High-rigidity structural stability, anti-deformation design
A precision-stamped thin steel plate skeleton is embedded in the seal as a rigid support structure. This design firmly maintains the overall shape and dimensional accuracy of the crankshaft oil seal, effectively preventing structural deformation during the installation process and dynamic operation of the engine. It ensures consistent fitting precision with mating components and avoids seal failure caused by shape distortion.
3.Upgraded precision dynamic sealing performance, zero oil leakage guarantee
The sealing lip is professionally coated with Polytetrafluoroethylene (PTFE) and equipped with a garter spring. This optimized structural design significantly enhances the sealing pressure of the lip and improves its adaptive conformity to the shaft journal surface. It achieves a tight and reliable dynamic seal between the seal and the crankshaft, effectively reducing the risk of engine oil leakage and ensuring the integrity of the engine lubrication system.
