MARINE SHAFT SEALING

WATER LUBRICATED

HOLLEX SEAL

The  Hollex  seal  has  a  new  design.  It is used with water lubricated stern gear installations. It works  according  to an entirely different principle than conventional seals. It seals axially, that  is  to  say along the length. A sliding ring made of high quality stainless steel is mounted onto the  shaft.  It  rotates  with  its  smoothly polished surface against a P.T.F.E. counter sliding ring. This  counter  sliding  ring  is  mounted in a vesconite housing, which is suspended flexibly in a rubber  bellow.  Due  to  the  relatively  small  sealing  areas  only  minimal  radial movement is allowed,  especially  with  the  smallest  diameters.  Therefore  the  Hollex  seal  must always be  installed as close to the fore bearing as possible. With its low frictional resistance, the life span of  the  Hollex  Seal  is  much longer than that of a conventional  seal .There will be no grooves due to the wearing of the packing or the lip seal, so the shaft can rotate freely.

Tides Marine Series One Seal

The Series One seal by Tides Marine is applicable for water lubricated sterngear systems. This seal is made of high quality composite material, that will not absorb water and handles temperature changes well. A water inlet is fitted as a standard on the Series One. The seal should be lubricated by the engine’s cooling water. The high flexible bellow will follow any shaft movement. The actual sealing is done by one lip seal.

Tides Marine SureSeal, For Single Engine Installations

The Tides Marine SureSeals are suitable for water lubricated sterngear installations. This seal is made of a high quality composite material, that is very endurable and will not absorb water. The material handles temperature changes well. The SureSeals have high flexible bellows and come with a water inlet fitted as a standard. The seal should be lubricated by the engine’s cooling water time as the SureSeal, a special Carrier kit can be slipped onto the shaft. These units allow lip seal replacement to be performed without releasing the shaft from the trans- -mission. And, if necessary, this replacement can be done while the vessel is in the water. SureSeals are ABS and Lloyd’s approved.

Tides Marine SureSeal, For Twin Engine Installations

This SureSeal unit has exactly the same abilities and advantages as the SureSeal for single engine installations, only this SureSeal is supplied with two water injections points. One inlet is for the suppy of cooling water from the engine, and one inlet is used to connect the seal to the second seal on the second sterngear installation. When only one engine is running, both seals will remain lubricated.

STB Seal EVO
This flexible seal is used in water lubricated sterngear installations and has it’s own waterinlet. This seal also has a grease supply tip to lubricate the lipseal. The seal consists of a flexible rubber socket and a hose clamp. Including a tube of “stuffy grease” and a water inlet.

STB Seal
This  flexible  seal  is  used  in  water  lubricated  stern gear  installations.  The  seal  consists  of a flexible  rubber  socket  and  a  hose  clamp. Comes complete with yellow protection sleeve for the seal and a tube of “stuffy grease”. 

MARINE SHAFT SEALING

GREASE LUBRICATED

Carco Seal
Carco lip seals are applied in almost every sterntube system, regardless of the lubrication. Lip seals are only applicable with housing, because lip seals are always mounted by meansof axial confinement. They are treated with the brandname Carcoflon coating. This seals the gap perfectly, they are self-lubricating and have a very low friction coefficient. The axial tension is provided by the built-in stainless steel spring.

Carco Seal – Split
Carco lip seals are applied in almost every sterntube system, regardless of the lubrication. Lip seals are only applicable with housing, because lip seals are always mounted by means of axial confinement. Uniquely, these seals are also available in a “split” version. This simplifies main- -tenance, because the propeller shaft installation does not need to be dismantled. With this design the rubber at both ends are a little softer with a guarantee to a perfect closure of the lip seal. Carco lip seals are treated with the brandname Carcoflon coating. This seals the gap perfectly, they are self-lubricating and have a very low friction coefficient. The axial tension is provided by the built-in stainless steel spring.
