Self-aligning inner bearing ZWB

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

The traditional design has a bronze body which attaches to the stern tube with a rubber cuff; and a seal unit the two lip seals for added security.

ZWBH seals are designed for use with water-lubricated stern gear and are supplied with a 10mm hose pillar (inner bearing for 25mm, 30mm & 35mm shafts) or 12mm (inner bearing for 40mm, 45mm & 50mm, shafts) for connection to the engine cooling system or to a dedicated skin fitting. The seals are supplied with stainless steel hose clamps and grease.

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

Please note that these self-aligning inner bearings are not usually stocked and as such, a lead time of 2-4 weeks will usually apply. Please contact us before ordering for availability information if your order is urgent.
