Hollex Seal

The Hollex Seal is an advanced solution for water-lubricated propeller shaft installations. Unlike conventional seals, this seal operates on a unique principle, providing axial sealing along the length of the shaft.

Key features and benefits include:

• Axial sealing: Seals the shaft longitudinally using a high-grade stainless steel sliding ring mounted on the shaft, which rotates against a composite counterface to ensure a perfect seal.
• Limited radial clearance: Due to the relatively small surface area of the sealing faces, only limited radial clearance is permitted, especially with smaller diameters, requiring precise positioning of the seal near the bearing.
• Long-term performance: Thanks to its low frictional resistance, the Hollex Seal lasts significantly longer than standard packing sets, thereby reducing maintenance costs.
• Elimination of run-in: Prevents leakage due to the absence of run-in on the propeller shaft, which is a significant advantage in terms of reliability and durability.
• Adjustment options: When preloading the seal, the axial displacement of the motor caused by the thrust of the propeller must be taken into account.

The Hollex Seal offers an advanced solution for efficient sealing and long-term performance in marine applications, where reliability and durability are essential.
