Shaft seals
Self-aligning inner bearing and triple shaft seal for extra security
ZWBH seals have been 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. Minimal friction, oil- and grease-resistant and with a separate ⅜” x 10mm hose pillar for water injection. As the ZWBH has a threaded connection, a valve can also be easily applied to it.
Depending on the length, diameter and RPM of the shaft, one, two or three cutless bearings will be required.
