lip seal vs oil seal

The seal carrier is made from reinforced polyamide (coloured black), while the seal lip area is made from thermoplastic PU elastomer (coloured green). Sealing rings SD are also suitable for use as wipers on shafts undergoing axial motion and allow stroke speeds of up to 3 m/s, depending on the surface quality of the shaft.

A grease seal, often called an oil or dirt seal, is a type of seal utilized to retain grease in a case or housing. Grease seals close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. Preventing harmful containments from entering machinery is another critical function of a grease seal.

The purpose of any seal is to protect a joining in a piece of equipment. Seals serve to keep lubrication or other liquids inside and contamination outside of the joint. A lip seal is also known as an oil seal or a rotary shaft seal. Oil seals or rotary shaft seals and mechanical seals are designed for moving parts.

As long as a lip seal is operationally effective and has not degraded to the point of shaft wear or elastomer lip wear, it is reasonable to assume that 160 watts of frictional energy are consumed by an average seal. At $0.10/kWh, that equates to $140 per year.

MSO Seals and Gaskets can custom machine lip seals as well as mold any lip seal you may require, Metric or Standard or special. Rubber grade used include: 

Operating temperatures for engine oil seals (see Fig. 14.1 1 and cross-section of lip seal with garter spring in Fig. 14.2 2) vary widely, depending on engine design and location within the engine.Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling.

TC oil seals feature a dual lip with a garter spring and utilize a rubber cover for improved sealing ability. SA seals, also known as Rotary Shaft Lip Seals, come in a variety of materials. Van seals, also known as radial lip seals, are used in a variety of industries including automotive, consruction, power generation, medical and aerospace.

The term interstitial seal is used for seals that allow unrestricted relative motion between the stationary and moving components (i.e. no seal to shaft contact) 

Trelleborg's portfolio of rotary seals includes the commonly known radial oil seal, rotary shaft seals, radial and axial lip seals, double-acting O-Ring energized Polytetrafluoroethylene (PTFE) rotary seals for shaft and bore, rubber V-Rings, mechanical face seals / heavy duty seals and many more.
