This marine integral-type rubber bearing is designed in accord with the CB*769-2008 standard. It is suggested to be used when the lubricating medium of stern tube is water and the water lubrication pressures is mo more than 490KPa(cooling water temperature is less than 55℃). It not only can save resource and reduce loss but also can be maintained without going into a dock. This integral structure may be used within Φ200 and the embedding structure would be used if excess Φ200. We can design our products according to customer’s requirements.

Features:

1. Material: rubber

2. Standard: CB*769-2008
