VETUS ZWBH Self-Aligning Inner Bearing with Triple Lip Seal | Ultimate Driveline Protection
Ensure the absolute integrity and smooth operation of your vessel’s driveline with the VETUS Self-Aligning Inner Bearing featuring an advanced Triple Lip Seal. Engineered for the discerning mariner who demands reliability and peace of mind, this essential component for boat motors provides a superior, watertight barrier for your propeller shaft system. The ZWBH represents the next evolution in marine seal technology, offering unparalleled protection and performance for water-lubricated stern gear.
This is a flexible inner bearing with a triple lip seal. The ZWBH seals are developed for use with water lubricated stern gear. This updated monoblock design works in the same way as the trusted ZWB seals, with the addition of one extra lip seal (three total) for added security. This enhancement provides an exceptional defense against water ingress, keeping your bilge dry and protecting critical components from saltwater corrosion. Experience exceptionally minimal friction, which translates to improved efficiency and reduced wear on your propeller shaft. The robust construction is both oil and grease resistant, ensuring longevity even in the demanding engine room environment. A built-in 10 mm vulcanised hose pillar for water injection guarantees optimal lubrication and cooling for the shaft, a critical aspect of modern stern gear systems. The ZWBH is ready for another round of dependable service, season after season.
Peak Performance and Unmatched Reliability
The genius of the VETUS ZWBH lies in its self-aligning capability. The housing is ingeniously flexible to absorb shocks and vibrations from the engine and propeller shaft. This significantly reduces noise for a quieter, more enjoyable ride and minimizes stress on the entire powertrain, from the engine mounts to the propeller. By accommodating minor misalignments, it prevents premature wear on both the seal and the shaft, extending the life of your entire stern gear assembly.
Maintenance is straightforward and designed for convenience. VETUS advises annual lubrication with silicon grease to keep this sterngear seal in optimal condition, a simple task that ensures years of flawless performance. The ZWBH seals can withstand a wide range of operational temperatures, from -15° to +85° C, making them suitable for boating in diverse climates. Versatility is a core feature, as these seals are perfectly suitable for use with VETUS bronze, steel, or GRP stern tubes. To facilitate a complete and secure installation, the set comes with two high-grade stainless steel hose clamps and the necessary grease.
