(1) Indicates the alarm temperature set point that the bearing should be continuously operated at on the specified generator frame size. Shutdown set points are typically 10° C (18° F) higher.
(2) All 1600 frame generators use a double-shielded grease for life bearing. Grease cannot be added to the bearing.
(3) 1800 frame generators and 3000 frame generators shipped before 2012 use double-shielded bearings with EA6 grease. There are no threaded holes in the bearing brackets for the grease tubes that are used to add grease. Therefore, no grease can be added to the bearings. Beginning in 2012, 1800 frame generators and 3000 frame generators that are shipped will use a single-shielded bearing with 2S-3230 grease. The front and rear brackets contain factory installed grease fittings, therefore, single-shielded bearings must be lubricated periodically. Reference the Parts Manual with package serial number to identify the bearing part number and to determine bearing lubrication requirements.
(4) All 2600, 2700, 1800 and 3000 frame generators shipped beginning in 2012, use a single-shielded bearing design. Replacement bearings received from the Parts Division will have a shield on each side of the bearing. The shield facing the outside of the generator must be removed when the new bearing is installed.Perform periodic bearing lubrication at the intervals that are shown
