Product Description

Product Description

 

Such Type seal is mechanical seal device that controls specific pressure of fiction on contact surface by cor-rugated tube expansion. It is mainly used for boats, especially high-speed boat, and it conforms Io GJB2479-95 Gen-eral Code for Stern Tube Seal of boats.

Features:

1. Simple structure and small amount of parts
2. Heat-resistenl and wear-reslstent material for stationary seal ring
3. No friction to propeller shaft and sleeve
4. Long service life: thanks to flexibility of corrugated tube, specific pressure changes slightly when axial vibration rises
5. Beable to operate in water with high silt content

Technical Parameters:

Propeller shaft linear velocity<6m/s
Propeller shaft axial travel<8mm,axial play 4mm
Propeller shaft radial jump: ±3mm
Low water leakage: below 40 litres/ day, only waler drop can be seen in navigation pause, or even no water drop at all.
