Breaking Down the Features of PSS Shaft Seal 1″ Shaft 1-3/4″ Tube
Specifications
- Shaft Diameter: 1″. This is the critical measurement to ensure compatibility with the propeller shaft.
- Stern Tube Diameter (D): 1-3/4″ to 1-7/8″. This measurement ensures proper fitment to the vessel’s stern tube.
- Total Length (A): 6.975″. This dimension is important for ensuring adequate space within the stern tube area for installation.
- Total Length (compressed) (Compressed A): 6.225″. This compressed length indicates the amount of pre-load achievable during installation.
- Rotor Diameter (B): 2.375″.
- Carbon Cuff Diameter (C): 2″.
- Stern Cuff Length (E): 1.5″.
- The PSS Shaft Seal is a mechanical face seal using a rotating stainless steel rotor against a stationary carbon flange. The carbon flange “floats” to compensate for misalignment and vibration, improving reliability.
These specifications matter because they dictate the fit, compatibility, and performance of the seal within the specific vessel. Correct measurements ensure a watertight seal, preventing costly damage.
