Hearing of sealing mechanical objects, we think of O rings automatically. Another very practically usable name that is heard of is the Lathe Cut Gasket. These are manufactured from a tube of rubber. During production, a mandrel is inserted into the tube and the rubber is cut while the mandrel is turned by a high-speed lathe machine. This technology gives a strong seal that can maintain its shape under stress.

When looking for a static seal, this is probably one of the most effective options for keeping lubricants in or contaminants out of your machinery’s sealed areas.Consider opting for lathe cut gaskets when you need beveled edge gaskets or tight tolerance gaskets. Due to the ability to maintain their design and shape under continuous stress, these have a long sealing life. Lathe cutting is also less expensive than some molded alternatives, making it a great economical option for large projects and the choice for industrial use.

The varieties avaialable in Lathe cut makes it another reason for the popularity.

Square
Its the most common one. The biggest difference between each kind of lathe-cut seal is the cross-section.there being around eight different types of cross-sections. Square is slightly bigger than the typical gasket cut, but it is the closest to that typical gasket size when compared to other cuts.

Cylindrical
Cylindrical cross-section lathe cut gaskets are the second thickest cut available on the market today.This gives you a thicker seal surface that is able to endure higher levels of pressure.

V-Groove
The v-groove cross-section is used almost exclusively on shafts. These gaskets seal against both dry and wet contamination and are great for rotary shafts as these use a centrifugal action that is perfect for rotary shafts.  

Chamfer
If v-groove gaskets are the most niche cut of all the lathe cut gaskets, chamfer seals come in as a close second. These are very similar to o-rings and traditional square cuts, with a small exception, that the Chamfer cuts offer six sides, like a pentagon with a flattened top. It gives you the option of doubling up on these seals and the surface can be set on both the inside and outside of a radial surface. It also has the ability to handle pressure better than simple gaskets or o-rings.
