Oil seals, often called a rotary shaft seal or grease seal, closes the gap between stationary and moving components in mechanical equipment — most often rotating shafts — helping prevent lubricant escape and stopping harmful materials, such as dirt, from moving in through the clearance. Oil seals are most commonly used in gearboxes, hydraulic cylinders, and related components.

Above, are all the components of an oil seal and all its naming conventions. Beyond selecting the correct size, the three primary selection criteria are Material, Lip, and Case. If you have an oil seal you’d like custom designed and made, send us your specifications through our Oil Seal Design Form.

Choosing the correct oil seal for your application is important. It is just as important that oil seals are installed properly, in which our step-by-step guide can be viewed here. Doing so ensures your desired oil seal fits and performs as intended. Oil leaks can happen even after replacing an oil seal if the shaft has wear groove damage, in which case restoration is possible with the installation of a shaft repair sleeve.

The oil seal size is specified by three dimensions: the rotating shaft diameter, the housing bore diameter, and the width (thickness). Because of the oil seal’s purpose, the correct size is critical to performance. The inside diameter of an oil seal is sized slightly smaller than the shaft diameter in order to seal lubricants inside and prevent harmful contaminants from entering. Oil seals are offered in both metric and inch sizes to ensure the correct fit. Oil seals can be looked up by size using the Oil Seal Size Chart, which narrows down oil seals as dimensions are entered.

Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition. When searching for oil seals via our online store, you will not only be presented with your selection but with comparable oil seals of the same dimensions. There are often viable style substitutions that are functionally compatible but with additional features. With over 50,000 unique oil seals in our database, you can cross-reference 215,000 part numbers of OEMs and Manufacturers. In the Search Bar above, simply type the OEM/manufacturer part number alone (no need to type the name), and the oil seals matching that part number will be displayed.

Oil seals offer numerous style options. With the most popular styles, each can be categorized as Good, Better and Best. The manufacturer most often uses a Good (or Better) solution which was the most economical version that would perform to specifications. When replacing that oil seal, you can use the exact style or choice a Better or Best solution if your exact style is not in stock. In the charts below, you can always move up to Better and Best styles which can be substituted. Our goal is to provide our customers with the best product fast so we will stock the Better and Best styles and price them competitively.

‘T’ Lip – dual lip with spring. The lip design includes a secondary dust lip to minimize particulates from entering the sealing region. This is the most common lip design.

Material selection is important to the life of a radial shaft seal. The elastomer’s resistance to temperature, abrasion, chemicals, weather, sunlight, and ozone can affect a profile’s longevity and performance. The two most prevalent materials are Nitrile and Viton. See our Oil Seal Materials page for details on compounds and chemical compatibility.

The most common and cost effective case materials are stamped from cold rolled carbon steel. The steel is then phosphate coated to aid in the molding process and to help eliminate corrosion during storage. A simply ‘L’ shaped geometry is the most cost effective case design but a number of case geometries are available to improve rigidity, positioning and removability. oil seal cases can also include rubber molded options which address such factors as corrosion, vibration and sealing characteristics.

‘V’ Lip – single lip without spring. This lip is designed for grease applications because the high viscosity of grease does not require a spring.

As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.

Lip selection is driven by the media type, shaft speed, pressure, temperature and contamination parameters. The media used in the majority of applications is either oil or grease. Lip designs generally include a spring when the media is oil because of its higher viscosity as compared to grease. There is also a double spring design when there is media on both sides of the oil seal. Lip designs can also include a secondary lip which purpose is to mitigate particulates from reaching the sealing lip. For additional protection of the oil seal from outside particulates, a V-Ring can be used in conjunction with the oil seal to eliminate particulates.

BR Case– The BR design is same as B with additional rubber coating on the leading edge of the case. This additional rubber coating is to ensure sealing when the oil seal is seated in the groove.

A2 Case– The A2 design also has a metal outside diameter but includes an inner case which provide structural rigidity. This case design is used when the diameter of the seal is larger and rigidity is required to maintain structural integrity during installation.
