Oil Seal
An oil seal is a sealing gasket for rotating shafts and is essential for any material that needs lubrication. Its main components are a metal bracket, a toroidal spring, and an elastomer.
| Categories of Oil Seal |
| End cap |
| The end cap is a gasket that provides an axial seal against a static surface. |
| Lip seal for sealing |
| The lip seal for sealing is for rotating shafts and is indispensable for any material that needs lubrication. |
| GIL Single-lips oil seals |
| Single-lip GIL seals are gaskets with a retaining lip on the rotating shaft. |
| GIL Double lips oil seals |
| Double-lip GIL seals are retaining seals on the rotating shaft. |
| Silicone seals |
| Silicone seals have good dry heat resistance, excellent low-temperature capability, and good ozone resistance. |
| GIL high-temperature seals |
| Those seals are characterized by good operation at high temperatures and good chemical resistance. |
Selecting a Standard Seal Design
I. "S" and "T" Lip Designs
The table below illustrates "S" and "T" lip symbols for general non-pressure applications. The "S" design is a single lip oil seal with a garter spring to provide consistent radial load against the shaft. The "T" design is a single lip oil seal with an auxiliary dust lip to provide effective light duty dust exclusion.
The table below shows approximate limits of the "S" and "T" oil seal lip designs.
| Shaft Diameter | Nitrile Lip Maximum Continuous Shaft Speed¹ | Maximum Continuous Pressure² | Maximum Total Eccentricity³ |
| General | 3,500 rpm | 5 psi | .020″ |
| .500 | 8,000 rpm | 5 psi | .004″ |
| 1,000 | 7,000 rpm | 5 psi | .006″ |
| 2,000 | 4,500 rpm | 5 psi | .010″ |
| 3,000 | 3,800 rpm | 5 psi | .013″ |
| 4,000 | 2,750 rpm | 5 psi | .017″ |
¹ Higher shaft speeds are possible using high temperature materials
² Higher continuous pressures are possible for shaft speeds below 200 ft/min
³ Higher eccentricity is possible if shaft speed is reduced
II. "V" and "K" Lip Designs
The table below illustrates "V" and "K" oil seal designs. The "V" design is a single lip oil seal. The "K" design is a single lip oil seal with an auxiliary lip for light dust exclusion. These are low cost seals designed primarily for retention of grease and similar viscous fluids.
The table below shows approximate limits of the "V" and "K" oil seal lip designs.
| Shaft Diameter | Maximum Shaft Speed | Maximum Continuous Pressure | Maximum Total Eccentricity¹ |
| General | 2,000 rpm | 4 psi | .005″ |
| .500 | 4,000 rpm | 4 psi | .003″ |
| 1,000 | 3,000 rpm | 4 psi | .005″ |
| 2,000 | 2,300 rpm | 4 psi | .006″ |
| 3,000 | 1,700 rpm | 4 psi | .008″ |
| 4,000 | 1,400 rpm | 4 psi | .010″ |
¹ Higher eccentricity is possible if maximum shaft speed is reduced
III. "WP" Lip Designs
The table below illustrates "WP" oil seal designs. The "WP" were designed as dust wipers (or, scrapers) for reciprocating applications such as hydraulic cylinder rods.
The operating limits for the "WP" design are only slightly different from the "V" and "K" designs:
Nonstandard seal designs, shown in the table below, are best for special applications that cannot be satisfied by standard designs.
Table Notes:
Metal O.D. seals are most suitable for steel or cast iron housing materials.
Rubber covered O.D. seals are preferred for soft alloy or plastic housing materials. They are also suitable for steel or cast iron housing materials.
Sealing
Sealing is a protection system for materials that prevents the flow of water and other fluids by means of the construction of impermeable surfaces or barriers.
| Categories of Sealing |
| Collars |
| Sealing collars are mainly used in hydraulic and pneumatic applications. |
| Gaskets |
| The gasket is a sealing washer applied to the rod or piston of the cylinders of heavy hydraulic systems. It consists of a head, rings, and a base. |
| Guide Tapes |
| The function of guide tape is water-proofing, guiding the piston rod or, absorbing the radial forces of the system and preventing contact between the sliding metal parts and fixed elements. It is also in a band format. |
| Joints |
| Gaskets for sealing are components of different materials that prevent the leakage of fluids to the outside of generally mechanical, hydraulic, or pneumatic elements. |
| Mechanical Seals |
| A mechanical seal is a sealing item that is typically used in industrial pumps. It prevents leaks, reduces friction, prevents the shaft from being worn, reduces the cost and maintenance time, and allows working at high pressures. |
| Oil Seal |
| An oil seal is a sealing gasket for rotating shafts and is essential for any material that needs lubrication. Its main components are a metal bracket, a toroidal spring, and an elastomer. |
| Rings |
| The sealing rings have the function of preventing the intrusion of fluids in generally hydraulic and pneumatic components. They have different designs. |
| Scrapers |
| Scrapers for sealing are pieces whose function is to prevent dirt from entering the cylinder. However, they must allow a light film of lubricant during the shaft's return. |
| Sealing Thread |
| Sealing thread is a material used for static sealing of caps or in the manufacture of tailor-made O-rings. It is recommended to use it under less demanding conditions not needing excellent resistance. |
