Your guide to finding the right Dichtomatik Oil Seal for your Application

Oil Seal Material

Dichtomatik shaft seals are made from a wide range of materials. Depending upon a customer’s application, the material color, durometer, and type can vary. Dichtomatik standard materials are NBR and FKM but other materials are available as needed and are listed below. We understand that chemical interactions play a role in your material selection. As an aid, a complete chemical compatibility guide is available here for you to use.

Nitrile – Lip Code N (NBR)

NBR seals are recommended for most common applications. Commonly referred to as a Buna Oil Seal or a Buna-N Oil Seal. The Dichtomatik standard NBR compound is a 70-durometer rubber and are compatible with water and most common mineral oils and greases.

Fluorocarbon – Lip Code V (FKM)

FKM compounds are premium lip materials offers higher temperature ratings and provide superior abrasion resistance in addition to superior wear and performance characteristics in an 80-durometer rubber. This material is also known to many of our customers as a Viton Oil Seal.

Silicone – Lip Code S (VMQ)

VMQ compounds offer the widest range of operating temperature conditions ranging from -60F to 390F (-51C to 199C). Dichtomatik standard VMQ compound is a 70-durometer rubber.

Measuring Seal Size for your best fit

Dichtomatik carries many sizes of both metric and standard sizes on the shelf, ready for immediate shipment in the most common profiles. For a fraction/decimal/metric conversion chart, click here.

Finding the proper size oil seal is based upon three dimensions:

Shaft Diameter / Inside Diameter (ID)
Housing Diameter (Bore) / Outside Diameter (OD)
Seal Width

With the case of a metric seal, numbers outlining the size may already be stamped somewhere on the exterior part of the seal. The order in which these numbers appear will represent the shaft diameter, bore diameter, and width as listed above and in this order. So, for example, a metric oil seal stamped with 35 75 10 will have a shaft diameter of 35 mm, an bore diameter of 75 mm, and a seal width of 10mm. These will closely align with the inside and outside diameter of the seal, but it won’t be exact as the seal presses into the bore, and the seal lip compresses onto the shaft.

But be careful. Standard measurement seals will have similar numbering stamped on its outer face as well. The format for standard seals however, follows an outside diameter, inside diameter, and seal width listing. A seal with the numbers of 300 212 37 embossed on its outer face would translate into 3” on the bore, 2. 1/8” for the shaft, with a 3/8” width. This dimensional listing distinction will help you in determining whether you are dealing with a metric or standard sized oil seal. When adapting dimensions from a standare size seal, the fraction-to-decimal chart above may be helpful.

If however, there are no numbers stamped onto the seal, a tool such as a caliber is recommended for most accurate results. Measuring the shaft, housing bore, and gland width in seal the seal would go into is preferable to measuring a used seal.

Standard Seal Lip Design

The five principal lip designs, shown below identify the most common lip designs for Dichtomatik shaft seals. It is important to remember that other, more complex, designs are available for special applications. However, the lip designs shown here represent those which will fill the needs of most seal requirements. These five principal lip designs are also supplemented by a range of more specialized designs for more specific application requirements. For additional information regarding available lip designs contact our engineering experts.

S = Single Lip with A Garter Spring.

Generally used for sealing lower pressure applications. However, not recommended for use in applications where the surrounding environment contains any dirt or contaminants.

T = Twin Lip with A Garter Spring.

Generally used for sealing lower pressure applications. The additional dust lip provides increased protection for the primary lip. The cavity between the two lips can also be filled with grease to limit shaft corrosion and allow brief operation without media lubrication.

V = Single Lip

Generally used for sealing a non-pressure media, especially for sealing grease or viscous fluids. These seals are also used for dust or dirt exclusion.

K = Twin Lip

As type V above, but the additional dust lip provides increased protection for the primary lip. The cavity between the two lips can also be filled with grease to limit shaft corrosion and allow brief operation without media lubrication.

Standard Seal Case Design (OD Design)

The following identifies the most common case designs for Dichtomatik shaft seals. It is important to remember that other, more complex, designs are available for special applications. However, the case designs shown here represent those which will fill the needs of most seal requirements. There are five principal case designs, described below. These five principal case designs are also supplemented by a range of more specialized designs for more specific application requirements. For additional information regarding available case designs beyond the standard listings, contact our Dichtomatik Engineering experts.

A = Outer Metal Case with Reinforcing Plate.

This type is designed with an additional inner case providing increased structural rigidity when a more robust design is required. Particularly suitable for larger diameters or when the seal is fitted from behind.

B = Outer Metal Case.

This type is most suitable for steel or cast-iron housing materials. The metal case gives a particularly firm and accurate seat in the housing, but static sealing on the O.D. is partially limited.

C = Rubber Covered O.D.

This type is preferred for soft alloy or plastic housing materials, as well as cast iron or steel. It is also more suitable to use this design in a replacement environment where minor damage to the housing surface has occurred.

F = Rubber Covered O.D.

Similar to design C but additional rubber covering fully protecting the internal steel case. Particularly suitable for applications where corrosion could be a problem.

M = Outer Metal Case with Rubber Lining

Similar to design B but an additional rubber lining covering the internal face of the steel case. Particularly suitable for applications where corrosion could be a problem.

Part Number Creation

Dichtomatik’s TCM line of radial lip seals incorporates the easiest and most complete part numbering system of any major seal producer on the market. All TCM part numbers are created from the dimensions of the shaft, housing bore, and width for each seal, together with a designation for special lip materials, and the lip and case style. Dictomatik part numbers appear differently for standard inch sizes versus metric sizes. Three dimensions, separated by X’s always designate metric seals. For example, a seal 25x50x10TC indicates a seal made for a 25 millimeter shaft, a 50 millimeter bore, a 10 millimeter width with a TC styple case and lip design. Inch sizes, however, simply show 5 digits for the shaft, bore, and width. The first two digits being the inch and and first decimal digit of the shaft size, the third and fourth digit represented the inch and first decimal digit of the housing bore, and the last being the first digit of the width dimension. An example of a standard inch size seal part number breakdown is illustrated below:

All dimensions are the actual application dimensions, not the actual seal dimensions, except for the seal width.
