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 10mm hose pillar for water injection.
