Flexible inner bearing, 30mm shaft diameter, with triple lip seal ZWBH30

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 in total) for added security. With minimal friction, oil- and grease- resistant and featuring a 10mm vulcanised hose pillar for water injection, the ZWBH is always ready for another round! VETUS advises annual lubrication with silicon grease to keep this sterngear 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 stainless steel hose clamps and grease.
