scope:

NOTE: This guide specification covers self-lubricated bearing materials for waterway and marine construction. These bearing materials are used for lock and dam applications ranging from critical bearing applications to light duty and electro-galvanic isolating applications. This section has been developed for USACE Civil Works projects.

In accordance with ER 1110-2-109, the USACE Hydroelectric Design Center (HDC) in Portland OR is designated as the Mandatory Center of Expertise (MCX) for hydropower engineering and design. HDC's policy is to use self-lubricating materials in hydroturbine applications. For applications involving turbines, consult HDC (Phone: 503-808-4200).

Sections have also been included on self-lubricated bearings used for product lubricated vertical shaft pumps. Product lubricated pump bearings are used for applications that require minimizing or eliminating the exposure to petroleum lubricants to be in compliance with environmental, biological, or other applicable regulations.
