[TowerTalk] Ham Antenna Rotator: The Teardown

[Bob K6UJ]

 Norm's Rotator Service on line says:   "either a white lithium or green emerald.  Under no circumstances should wheel bearing grease or any other grease with fibrous material content be used". 
As they said, wheel bearing grease is a fibrous grease and should not be used.  There is a large selection of greases that are non fibrous.    There are many (non fibrous) grease lubricants better than Lithium which are rated for more severe service and lower temperatures than the Lithium.  I am planning on using a synthetic grease in my rebuild.  It  will be an overkill for California but I will sleep well at night.  hihi

  Years ago I remember reading to not use grease on the ball bearings as it just attracts dust and dirt. And, that the design from the factory did not call for grease. Is this correct or should one use a grease on the ball bearings? 73, Rod/w7zrc
