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 Clipper Oil Seal is the anchor of the rotary seal product line. The Clipper design features an integrally molded rubber fiber outer case and an elastomeric

Lip seals are items which, if cut across, show the presence of one or more sealing lips on the inside or outside diameter. This type of seal is necessarily used for all types of dynamic

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

V-ring seals are mounted on shafts and their thin, tapered lip seals against a surface (counterface) at right angles to the shaft. No special demands are placed on the surface finish of the shaft seating and the V-rings act as flingers, since they have an interference fit on the shaft and rotate with it.

PTFE LIP SEALS. PTFE lip seals are formed or machined from wear resistant PTFE or TEFLON™ (trademark is owned by The Chemours Company) composites for long life, low friction, high surface speeds, poorly lubricated conditions and soft shafts. Available with metal backing or o-ring on the seal OD for support and to prevent seal rotation.

When the wide contact principal; is applied to PTFE lip seal designs - especially spring-activated elements - the design parameters of the seal must prevent "bell mouthing." This effect will create an oil wedge and produce high leakage rates. Levels of interference between the element ID and shaft OD may vary.

Lip seals. Lip seals may be considered as a special type of precision gasket. They are available in different shape of the cross section, as for instance with single lip, with double lips, with

The innovative 33K split design eliminates the need and associated costs for equipment disassembly while improving seal performance of conventional lip seals. Installation time can be reduced from hours to minutes because the split assembly is unitized installing quickly and easily. The patent pending split design eliminates the need for

Lip Seal Gaskets - High Pressure Seal Weld Gaskets - By Spetech - Diaphragm Metallic Gaskets

Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals. Rotary Shaft Seals for Grease Also known as grease seals, these are designed to retain thick lubricant at low pressure.

2020. 8. 14. · If weld ring gaskets are used with auxiliary gaskets, the flange and bolt calculations must be carried out once for the weld ring gasket with the seal diameter to the outermost seal seam and once for the auxiliary gasket. With the use of auxiliary gaskets, a gap of 0.3 mm remains between the weld ring gasket halves, depending on the design. Note:

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

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.

General-purpose seal technology. Seals are indispensable sealing devices used in automobiles, airplanes and other vehicles, construction machines, equipment at petrochemical plants, home appliances, and various other machines. NOK offers a wide variety of seal products of very high reliability, including oil seals, based on its constant and focused research on materials,

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 FlexiCase seal is a metal-cased rotary lip seal suitable for applications where elastomeric lip seals fail and mechanical seals are too costly. The filled PTFE element provides greater chemical compatibility, wider temperature ranges, higher pressure capabilities, and longer life than elastomeric lip seals. ** Elgiloy® is a registered mark

How lip seals work. Lip seals work with a small contact area on the liner, which in turn is placed around the shaft. The seal works due to a hydrodynamic lubricating film between the lip seal

Radial shaft seals that are primarily used for contaminant exclusion should be installed with the lip pointing outward. When additional protection is needed,
