the time of leather Seals or mechanically fixed elastomer
sealing lips, there had been great development in Anti-Fluid
Sealing. The press vulcanization of the sealing member &
its enhanced fluid capability and heat resistance over period
of time made possible reliable sealing newer engines.
radial lip seals fulfill the basic requirements of being
leak tight with a minimal frictional loss at the point of
Sealing & satisfactory service life over longer period
of time. The manufacturing of radial lip seals involves
comprehensive know-how, continuous development and specialized
production equipment. For this reason only the raw material
are bought in i.e., raw rubber, fillers, retarders, plasticizers,
steel sheets bonding agent & spring steel wire; all
other processing & compounding is done in house.
Seals meet the Quality requirements as per relevant standards
viz IS: 5125/5129, SAE-J-110/111, JIS-B-2402, DIN-3760.
main areas of our seals are in vehicles and engine construction
such as Crankshaft, Camshaft, Gearboxes, Rear axles, Differentials
and wheel bearings.
Seals mainly consists of either Rubber clad, Metal clad
or closed type Seals which are most common, The Sealing
lip is molded with metal ring & consists of elastomer
element and spiral spring. Other designs of Seals are also
made as per customer’s drawings and specifications.
sealing of the radial lip is affected by mean of radial
force exerted on the shaft by radial lip. In the dynamic
sealing, hydrodynamic grooves are provided for pump back
action of sealing lip towards the oil side, Seal are also
doubled and tripled lip for dust or moisture protection.
The hydrodynamic grooves are either unidirectional or birotational.
All other features meet the demand of effective oil sealing.
We are one of the few in India to produce molded lip Seals
as per International Trend.
elastomers are used in shaft sealing such as Nitrile, Poly-acrylic,
Silicone, Flouroelasotomer, HNBR etc. Selection is made
with regards to the following influences:
