Michell design and manufacture whitemetal (babbitt) lined, spherically seated bulkhead glands complete with grease pumps. These components provide a limited leakage seal at the point where the propeller shaft pierces the bulkhead in the event of operating under flooded compartment conditions.
A major advantage of the Michell design is that it operates in the same way as a conventional bearing throughout its operating life with no wearing parts. It accepts radial movements of up to 40mm and angular movement of ±10° and does not require activation in the event of a flooded compartment condition.
