Figure 1 illustrates standard single lip design. The "ES" type designs are the single lip oil seal with a garter spring to provide a consistent radial load against the shaft.
Figure 2 illustrates standard double lip designs. The feature of "ET" type designs, corresponding to "ES" type, is the additional lip to prevent dirt and corrosion.
- WORKING CONDITION : suitable for "ES" and "ET" type oil seals

Note:
(1) in high shaft speed, it's more possible to use high temperature materials such as polyacrylate, silicone or fluoroelastomer.
(2)slightly higher continuous pressure is applied to shaft speed below 200 ft./min. |
