Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.

Auto oil seal Features
The sealing element makes up the interior of the oil seal, and the materials commonly used are:
0.4 to 1.6 μmRa,
1.6 to 6.3 μmRz
2. For rubber O.D. wall type:
1.6 to 3.2 μmRa,
6.3 to 12.5 μmRz
(Firmly affixes the oil seal and prevents leakage through the seal O.D.)



When the bore and shaft centers are misaligned, seal life will be shortened because the wear will be concentrated on one side of the sealing lip.
JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.
Oil seals are used to keep chemicals apart from lubricants such as oil/fat or water away to keep spinning shafts or bearings in proper working condition. Rotary shaft Seals are among the most commonly used seals for sealing lubricating oil, water or grease in different applications.
