ROTARY SHAFT SEAL

Radial shaft sealsRadial shaft seals are used between rotating and stationary machine components (fig 1) or between two components in relative motion and consist of two main parts:

A cylindrical outer covering of sheet steel (case) or an elastomer that has the requisite interference fit to seal statically against the housing bore.
A sealing lip made of an elastomeric or thermoplastic material that seals dynamically and statically against the shaft. The lip has a sealing edge that is formed by moulding, cutting or grinding. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring. The edge of the sealing lip and the shaft counterface surface form the most important functional area of a radial shaft seal. The sealing effect of the lip can be enhanced by designing the contact area of the lip with hydrodynamic features.

fig 1Some radial shaft seal designs have an auxiliary lip that protects the primary sealing lip from dust and other contaminants. A suitable lubricant in the space between the primary sealing lip and the auxiliary lip can reduce wear and delay corrosion. Contaminants that have passed the auxiliary lip will eventually cause damage in the counterface surface area. A build-up of heat can also occur between the two lips, resulting in premature wear.

Radial shaft seals are used in a multitude of applications. Because of the importance of radial shaft seals for the operational reliability and service life of machines and equipment, both seal manufacturers and users are equally interested, to some degree, in standardization. This has led to the establishment of national and international standards and guidelines listed in the table. These cover boundary dimensions, tolerances, material specifications, test methods and terminology as well as the basic outside diameter constructions and sealing lip arrangements.

Oil seals are used to protect shafts and bearings from ingress of dirt and foreign matter and egress of oil or grease. An oil seal generally consists of an outer circular metal part and an inner flexible member that does the actual sealing and is bonded to the metal part by chemical adhesive agents.We offer the following types of oil seals:

General Purpose High Performance Oil Seal.
Rubber Fabric Oil Seal.
Rotary V-Seal.
PTFE O-Ring Energised Oil Seal.
PTFE Metal Case Oil Seal.
PTFE Spring Energised Oil Seal.
PTFE Lip Oil Seal.
Rotary Shaft Seal
Double Lip Oil Seal

Oil Seals (Rotary Seals)

Oil seals (also known as rotary seals or shaft seals) cover a wide range of applications ranging from domestic equipments to automotive and power plant machinery, industrial pumps, gas and aircraft turbines and compressors.

If yours is a modern system, the surface speed can go up to 30 m/s and operating temperature can be as high as 250 degree Celcius. For these type of oil seals, our general purpose high performance oil seals can be employed. When the speed is increased up to 90 m/s, the lip will be produced using PTFE based compound to reduce heat generation. For high pressure applications, we offer a wide range of oil seal profile made using PTFE based compounds.

Here at Bright Indotech, we make and design reliable oil seals for your demanding tasks. If the oil seal is not selected properly, then even a few percents of leakage can be inconvenient and incur expenses to a large number of users, as well as cause environmental pollution. Note that the oil seal is not only to seal lubricating oil, it can also be used to seal other fluids such as water, foodstuff and chemicals. We understand that the reliability and reputation of your system depends on the well functioning of these oil seals.
