STS-B Water Lubricated Propeller Stern Shaft Sealing Device

STS-B Water Lubricated Propeller Stern Shaft Sealing Device

Introduction:

Seal type STS-Bis mechanical seal device that controls specific pressure of fiction on contact surftace by cor-rugated tube expansion.

It is mainly used for boats,especially high-speed boat,and it conforms to GIB2479-95 Genneral Code for Stern Tube Seal of boats.

Features:

A: Simple structure and small amount of parts;

B: Heat-resistent and wear-resistent material for stationary seal ring: No friction to propeller shaft and sleeve

C: Long service life: thanks to flexibility of corrugated tube.specific pressure changes slightly when axial vibration rises;

D: 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 waterdrop can be seen in navigalion pause,or even no water drop at all!
