Axial seal TFTB type
TFTB AXIAL SEAL
A new generation of TFTB Axial Seal for lubricated shaft lines in sea water has been introduced by Eliche Radice.
The planning was carried out following solid and reliable criteria in order to guarantee a perfect hold, even in the worse conditions.
The TFTB Axial Seals are easy to fit and they guarantee an excellent hold even in the presence of shallow, sandy waters.
The range covers a shaft line of 50mm up to 105mm diameter.
The TFTB works due to the contact between the flat surface of the stationary fixed part composed of graphite carbide and a stainless steel 316L rotating ring that is fixed onto the propeller shaft.
The contact function between the two surfaces is guaranteed thanks to the linear and concentric pressare exerted by the correctly loaded rubber part and by the water pressure inside the seal.
The interfacing materials, with their special caracteristics, are highly resistant to abrasions and they noticebly reduce the negative effects of galvanic corrosion.
Thanks to its particular design in a static position, rubber body of the seal absorbs the misalignments and vibrations, so reducing maintenance costs.
The rubber body of the seal is fixed mechanically onto the bronze stuffing box head complete with a bushing made from hydrolubricated rubber, in order to guarantee
a perfect locking and render any unscrewing impossible.
- Scratches, corrosions and overheating of shaft lines due to the stuffing box packing are elimi nated.
- Easy to fit and substitute.
- Dry bilge.
Differently to other lubricated seals with polluting oil or grease, these seals are lubricated with a sea water, a natural ecological lubrification.
The elastometric ‘CR’ rubber body is self-extinguishing and resistant to heat.
The rotating ring and the stationary fixed part have a symmetrical shape and they allow the use of any contact surfaces, so having a double life span.
- They absorb the vibrations and the misalignments of the shaft.
- Reduced encumbrance dimensions.
- Long intervals between maintenance operations.
- Almost no maintenance and low costs.
No corrosive material containing of hydrocarbons or battery sulphuric acid vapor must come into contact with the seals.
The rubber sleeve must be inspected regularly and substituted every 5 years. If any scratches are noticed, it must be replaced immediatly.
