CX / DX Type oil seals

Structure
The KEMEL Seal (CX type, DX type) is composed of
three types of metal rings (flange ring, intermediate ring, and
cover ring), assembled by bolts. These metal rings form a casing,
and the sealing rings are tightly fixed between metal rings. The
metal rings are in contact with each other, which assures that the
compression of the sealing rings is always maintained to the proper
degree, preventing the risk of cracks occurring by excessive
pressure on sealing rings. These sealing rings are all identical in
design, and normally an aft seal is equipped with three sealing
rings and a forward seal with two sealing rings.

Features
1)Best sealing ring design through highly advanced technologies
The KEMEL Compact Seal (CX type, DX type) gives excellent
sealing performance, easy handling, and stable quality over a long
period of time, by utilizing the latest design technology and
specially developed sealing ring shape and material.

2)A sealing ring material with superb durabilityThe sealing rings
come in two kinds of materials - FKM (fluroric rubber) and NBR
(nitrile-butadiene rubber) - for selection depending on the
operating conditions of stern tube seal. The FKM sealing ring fitted
on the Compact Seal has superb heat resistance, with a special
fabric vulcanized on its surface to assure high strength and
durability. With its superior structure, the FKM sealing ring
features the important property of being free from the danger of
crack generation under heavily loaded conditions.

3)A chrome steel liner with superior abrasion and corrosion
resistanceA special grade of high-chromium stainless steel
developed by Kobe Steel is used for this liner. (Patent No. 5736974)
This new chrome steel liner is far superior to conventional chrome
liners in its abrasion and corrosion resistance, and is highly
effective when used as the aft liner where pitting corrosion is liable
to occur.

4)Repeatedly machinable liner Our chrome steel liners are provided
with a sufficient machining allowance, so that the worn-out liner
can be repeatedly reused after machining.
