All weld-ring gaskets should have a surface roughness ot Rz- 25 to 50 cHemClC I nc Hollow Lip Weld-Ring Gaskets Weld-ring gaskets with hollow lips according to profile A24, A25 and A23 offer improved stress conditions in the seal weld. The use of weld-ring gaskets w th hollow lips is

Advantages: Secure sealing on unpaved and stainless steel shafts. No traces of damage on the surface. No need for treatment of the shaft surface (coat, temper, nitrate,), nor the use of extra sleeves. Thanks to the tangential and radial tension on the lip seal, no pump effect is provided. Low friction coefficient, low friction losses. Longer

Extruded lip seals and extruded gaskets are available in a wide variety of standard cross sections and materials. Lips are engineered to seal as a wiping motion to clean and/or prevent dirt and liquides from contaminating your enclosures. Munaco Sealing Solutions has the right extruded lip seals for you application. FEATURES

Novotema works in close collaboration with customers to design and develop application-specific lip seals, v rings, axial shaft & radial shaft seals Custom

This guide is intended to give design engineers the basic facts needed to begin the process of designing effective rubber seals, gaskets and weather 

SPETECH® has been in the industrial sealing systems for 30 years. Through all this time we've been collecting experience and supplying our products to 100 

Single lip hydrodynamic rotary seals utilize a specially formed sealing lip that offers a hydrodynamic sealing advantage to retain fluids throughout the dynamic 

Traditionally, lip seals have been used to seal low (7-psi to 10-psi) pressures, but newer lip seals designs now can seal 150-psi or greater on rotary equipment. This relatively new version of the older technology has evolved because of the advancements in sealing element materials.

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 oil seal normally consists of three basic components: the rubber sealing element, the metal insert (case) and the garter spring. The purpose of the sealing 

FlexiLip seals are rotary seals incorporating a deflected lip seal geometry. Anti-rotational devices such as flanges and. O-rings are often 

If it becomes apparent that you need a custom design to meet your unique needs, or if you just want us to confirm the standard seal choice you've made, please contact Parker's PTFE Engineering team at 801-972-3000. As with all design engineering, tabulations contained herein are provided for use as a guide only.

Therefore, soft rubber materials for gaskets (nitrile rubber, fluororubber) should be combined with soft resin materials for back-up rings (PTFE), and in the case of use in a high-pressure area, a combined use of PTFE with polyamide resin, which is a harder material for back-up rings, is desirable. Example of use of gaskets (U-gaskets)

The typical geometry for a radial lip seal, commonly known as an oil ring, is shown in Fig. 14.16 These seals are used to retain lubricants and exclude dirt, and are well suited to moderate-speed and low-pressure applications. The use of a radial lip seal for a bearing is illustrated in Fig. 14.17.

SPETECH Weld Ring seals are manufactured to fit to EN, ASME, DIN,. GOST, JIS, WN, OST or any other standards flanges. Commonly they are individually designed 

Whatever you call it, however you may use it, this book is dedicated to helping you design a successful sealing solution. We hope you turn to it often and we 

The hollow lip optimises the state of tension in the gasket seam between the two halves of the weld ring. If a closed design and non-destructive testing are deemed to be of value, or if the assembly expense is to be significantly lower, we are happy to design our type A42 weld-ring gaskets, corresponding to your requirements.

Lip Seals Energized lip seals comprise of a high modulus elastomer, (or high grade engineering plastic) jacket and a low modulus elastomer O-ring energizer. The low modulus O-ring energizes the jacket under low pressure conditions to increase the sealing force allowing them to be used in low and high pressure applications.

In terms of seal history, the crimped case seal, or CCS, is a relative newcomer, entering the market about 10 years ago. The crimped case seal's hallmark design feature is that it can use as little as 2 components: the sealing lip and case. This is in contrast to a traditional design that usually requires 4 components to accomplish the same task.

The RSH heavy-duty seals replace the RS1 seals currently used. Fig. 4 shows the difference between the two seal designs. The lip of the RS1 seal makes radial contact with the outer diameter of the inner ring. With the RSH seal, the lip of the seal is in contact axially with the inner ring in a groove at the side and incorporates a secondary lip.
