PSS HS 55M LOG 3-1/4

PSS 02-55M-314 - Dripless Shaft Seal 55 mm, 3 1/4" Stern Tube

The PSS 02-55M-314 Dripless Shaft Seal is a robust mechanical face seal designed for reliable performance in demanding conditions. Featuring a stainless-steel rotor and a carbon flange, it provides effective sealing between rotating and stationary components. The design ensures constant contact and accommodates variations in propeller thrust, while the floating carbon flange helps to mitigate misalignment and vibration issues.
