Standard and custom made lip seals

Darcoid Nor-Cal Seal has been providing standard and custom-made lip seals for a wide range of applications and industries for a long time as an industry leader and has been providing lip seals for various applications where quality is of utmost importance. A lip seal is nothing but a rotary seal incorporating a deflected lip seal geometry. Anti-rotational devices such as flanges and Orings are often utilized to prevent the seal from rotating along with the shaft. Lip seals are suitable for sealing corrosive and abrasive media. A wide range of geometries and materials are available, depending on specific application requirements. Lip seals are often used on motors and compressors and other components with high speed rotary shafts for their ability to resist extreme pressure.

The most common lip shape is the chamfered or back-beveled design and is available with the V and C Series spring types. This design allows for ease of installation and permits lubrication to nest under the lip and feed through in reciprocating dynamic applications. The result is a microscopic film of lubrication that increases seal and hardware service life. Since contact point of a chamfered lip is a single point, all of the sealing force is concentrated on that point, yielding the highest sustainability and lowest friction.

Lip seals

Applications often involve media with abrasive particles that can get caught between the seal lip and the mating hardware. This increases wear and tear to both the seal and the mating surface. To prevent particles from accumulating, the scraper lip design is available with all three spring types. The scraper lip contact point is positioned directly over the load point of the spring in each design for maximum scraping action. The scraper lip can be positioned on the ID, OD or both. The scraper lip also stays in place better in a stepped gland where the step is not very large.

The beaded shape contacts the surface in much the same way as an O-ring, and is available with the V and H Series spring types. Similar to the chamfered lip, it is easy to install and helps to lubricate the reciprocating sealing surface. In fact, the beaded lip yields a film of oil that is slightly thicker than that of a chamfered lip, making it advantageous for applications with rapid reciprocating motion. Standard and custom of lip seals sizes are available with a wide selection of PTFE materials. Darcoid Nor-Cal Seal is an excellent supplier of lip seals.
