5.3.2 LUBRICATION

American Rotary phase converter idlers/generators are custom made and come with pre-packed bearings

using the lubricant specifically designed for this idler . Exxon Polyrex EM high temperature bearing grease or

equivalent polyurea lubricant is recommended for the Baldor Idlers and can be purchased through American

Rotary .

DO NOT use Lithium based lubricants . These may cause premature bearing failure and will void the warranty .

Be careful not to force so much grease into the bearings that the excess finds its way into the windings of the

idler . Some idlers have sealed bearings and will never require greasing even though they contain grease fittings

(applies to all 5, 10 and 15 sizes) . For all other units use the following rule of thumb for scheduled maintenance:

For use of the phase converter that is less frequent, add grease to the idler bearings approximately every 6

months . For more frequent use, add grease to the idler bearings about every 3 months . When adding grease,

one or two pumps for each fitting will be enough .

If your unit requires greasing, remove the plastic circular cap on each side of the AMP enclosure to gain access

to the grease zerk as seen in the photo below .
