What is Oil Seal, a component of machine that seals lubricants, an oil seal is constructed of rubber,garter spring, and an internal case. While preventing the leakage of lubricants,water,or chemicals,an oil seal also prevents the entry of dust and dirt into a machine.
Oil seal also called as dynamic seal is use to prevent leakage of fluid between two components having relative rotary or sliding motion.
Skeleton oil seal is normal for a variety of mechanical bearing, especially the rolling shaft parts, to guarantee the normal work of the bearing and other pure rotational parts. its function is to put the oil cavity and the outside world, photosensitive oil sealing, sealing outside and dust.
U shaped coil is commonly used in the hydraulic cylinder seal, it is a kind of typical lip seals, whether for piston rod, can obtain good effect. Polyurethane u shaped coil is mainly used in hydraulic cylinder, it has good mechanical properties, good oil resistance, is the most commonly used in hydraulic oil cylinder, high sealing material.
