Description

Standard Fin Sizes: 45 sq.ft. (4.18 sq.m), 53.8 sq.ft. (5.00 sq.m), 64.6 sq.ft. (6.00 sq.m), 75.3 sq.ft. (7.00 sq.m)
Fin Attachment:  Precision machined oversized self-locking taper. A precision machined spiral groove along the length of the tapered surface allows for easy, hydraulically-assisted fin installation.
Main Shaft:  8.0 in. dia. (203.2 mm) heat-treated stainless steel.
Fin Actuator Housing Material:  High strength ductile iron; 2.5 times stronger per square inch than aluminum.
Upper AND Lower Bearing: Heavy-duty tapered roller bearings by a leading manufacturer such as Timken (TM).
Lower Seal:  Three double-lip seals for maximum seawater protection. Easily accessible in a 316 stainless steel retainer.
Upper Seal:  Double-lip, spring-loaded seal for grease retention. The double-lip design also provides protection of the fin actuator against external contaminants.
Lubrication:  Pre-packed with high quality Lubriplate (TM) water-resistant grease for lifetime maintenance-free service.
Hydraulic Connections:  SAE O-ring ports and (JIC) 37° flare fittings (not pipe fittings) for leak-free service.
Hydraulic Cylinder:  Custom engineered for NAIAD stabilizer applications in collaboration with a world leading cylinder manufacturer. Double acting twin cylinder arrangement. Steel body construction with high strength tie rods for heavy-duty service. Self-regulating shock reducing cushions.
Cylinder Mounting:  Head Trunnion mount allows most compact Fin Actuator design. Trunnion freely pivots in dual high capacity roller bearing assembly.
Maximum Working Pressure: 
Cylinder Bore Diameter:  4.00 in. (101.6 mm)
Rod Diameter:  2.50 in. (63.5 mm)
Rod End:  High strength hardened steel rod end with sealed heavy duty precision double row spherical roller bearings.
Rod End Pins:  Through-hardened, ground and passivated stainless steel.
Torque Arm:  Cast and heat-treated high strength ductile iron, cadmium plated for corrosion resistance. Honed bore for precise Rod End Pin fit.
Shaft-Torque Arm Connection:  Oversized clamped precision spline for maximum torque capability.
Overall Weight: 
Overall Dimensions:  See dimensional drawing.
Fit & Finish Throughout:  High ‘yacht’ quality, painted, plated and polished.
