VETUS Self-Aligning Inner Bearing & Triple Shaft Seal
This is a self-aligning inner bearing and triple shaft seal for extra security.
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.
Minimal friction, oil and grease resistant and with a seperate 3/8” x 10 mm hose pillar for water injection.
As the ZWBH has a threaded connection, also a valve can easily be applied on it.
VETUS advices annual lubrication with silicon grease to keep this stern gear seal in optimal condition.
ZWBH seals can withstand temperatures between -15° and + 85° and are suitable for VETUS bronze, steel or GRP stern tubes.
The set comes with two (2) stainless steel hose clamps and grease.
