Acrylonitrile Butadiene Rubber (NBR)

Hardness	Spareage Code
NBR 70°/75° Shore 'A'	NT4/b
NBR 80°/85° Shore 'A'	NT5/b
NBR 90°/95° Shore 'A'	NT6/b

Commonly known as NITRILE or BUNA-N.
Nitrile rubber is the sealing material most frequently used in Hydraulic & Pneumatic systems because of its excellent resistance to mineral oil based fluids, greases, water & hydrocarbon fuels. It has good physical characteristics such as abrasion resistance and good compression set.
NBR is not suitable to Aromatic hydrocarbons, chlorinated hydrocarbons, automotive brakes fluids, and some fire resistant hydraulic fluids.

Hydrogenated Acrylonitrile Butadiene Rubber (HNBR)

Hardness	Spareage Code
HNBR 70°/75° Shore 'A'	NT42/a
HNBR 80°/85° Shore 'A'	NT42/b
HNBR 90°/95° Shore 'A'	NT34

HNBR has good heat resistance, oil resistance & resistance to number of aggressive chemicals. The material exhibits high mechanical strength and improved abrasion resistance. It also has superior resistance to weathering, ozone and hot air and very good resistance to technical oils, even in the presence of hydrogen sulphide and amines.

HNBR with PTFE Filler

Hardness	Spareage Code
HNBR 80°/85° Shore 'A'	NT34/b

This specially developed compound is very good for low friction and low abrasion resistance. Mostly this material are used for seals subjected to dry run.

---

Polyurethane (PUX)

Hardness	Spareage Code
92°	PUX

PUX material is a special grade polyurethane capable to withstand temperature upto +110 C, compared to normal grade PU material. Besides temperature resistance it exhibits good wear & tear properties, abrasion resistance, extrusion strength and good flexibility.

---

Polyamide (Nylon)

Hardness	Spareage Code
M 95°	NY-X

NY-X grade polyamide have capability to withstand temperature upto +290°C compare to other grade polyamide. It has good slide and wear characteristics. The materials are continually resistant to solvents, grease, fuels, oils and acids. Strong acids, alkalis and hot water attack polyamide.

Taper Roller Bearing Seals -
Marina Engineering Corporation (Spareage) had developed inner & outer seals for Taper Roller Bearings used in work roll and intermediate roll chocks. AZI & AZZ seals are constructed with a metal insert with rubber covered outer diameter. Spring loaded single and dual lip made out of FKM or HNBR elastomer.
