Oil
Seals -
Introduction
1)Oil Seals are used to
prevent oil leakage from rotary shaft and housing
clearance.
2)It has a flexible lip that
rubs against an shaft or housing to prevent leakage or ingress of
fluid and dirt.
3)Seal selection is based on
shaft diameter, housing bore diameter and width, shaft speed,
working termperature, fluid, pressure differential and service
conditions. Common configurations include single lip, double lip,
triple lip and four or more lips.
4)Rubber sealing element or lip
material choices for oil seals include: Nitrile Rubber (NBR),
Acrylic Rubber (ACM), Silicon Rubber (VMQ), Fluorocarbon Rubber
(Viton/FKM), Ethylene Propylene Rubber (EPDM), Tetrafluoroethylene
Resin (PTFE). To resist wear, the compound durometer (hardness) is
typically *0 to *5 shore A.
Notes
1) Metal encased seals are most
suitable for steel or cast iron housing materials, with low
coefficient of thermal expansion and fine
finishers.
2) Rubber covered O.D seals are
most suitable for soft alloy or plastic housing materials and also
suitable for steel or cast iron housing materials, with high
coefficient of thermal expansion and rough bore
finishes.
Material are available in
Buna-N (NBR) and Viton® (Fluorocarbon

| Type | Temp Range (C) | Features | ||||||||
| Lower Limit | Upper Limit | |||||||||
|
Nitrile Rubber (NBR) |
**0 | ***5 |
This material is most often used in oil seals due to its excellent resistance to mineral oil and abrasion ; however, oil seals made of this rubber cannot be used for polar solvents, such as ketone or ester. |
|||||||
|
Hydro-genated Nitrile Rubber (HNBR) |
**5 | ***0 |
This rubber has similar characteristics to nitrile rubber for oil seal use, but has better resistance to heat, oils, and weather than standard nitrile rubber |
|||||||
|
Acrylic
Rubber (ACM) |
**5 | ***0 |
This rubber has the same good oil resistance as nitrile rubber, and has good heat resistance similar to silicone rubber. Weather resistance is also excellent. Resistance to alkalis or water is inferior to that of other types of rubber |
|||||||
|
Silicone
Rubber (VMQ) |
**0 | ***5 |
This rubber is highly resistant to heat, cold, and weather, but its resistance to alkalis or water is inferior to that of other types of rubber |
|||||||
|
Fluoro-carbon Rubber (FKM) |
**0 | ***0 |
This rubber has heat resistance surpassing that of silicone. It also has excellent resistance to oils and chemicals. This material is the best rubber for oil seals due to its well-balanced characteristics. |
|||||||
|
Ethylene- Propylene Rubber(EPDM) |
**0 | ***5 |
This rubber has excellent resistance to water, polar solvents, inorganic chemicals, and weather, 7Its oil resistance is inferior. |
