Self-aligning inner bearing ZWBH

Flexible inner bearing with triple lip seal. Suitable for Vetus bronze, GRP or steel stern tubes. The flexible design absorbs shocks and vibration.

The updated monoblock design works in the same way as the trusted ZWB seals, but with the addition of one extra lip seal (three in total) for added security.

ZWBH seals are designed for use with water-lubricated stern gear and are supplied with a 10mm hose pillar, for connection to the engine cooling system or to a dedicated skin fitting. The seals are supplied with two stainless steel hose clamps and grease.

We advise lubrication once a season with silicon grease to keep the lip seal in optimal condition.
