Installing a thrust bearing in a tower - Dead weight (along the gravity vector) all on the rotator or all on the thrust bearing? Seeing such things as sleeves for towers, I would surmise that all of

Probably one or the other, not both. That's "overconstrained", which means anything just slightly out of true can produce very large forces. The easiest way is usually to let the rotator take the ver

The answer is in the name: "thrust" is another name for force along the axis of the shaft/mast. The classic example of a thrust bearing is the bearing in a power drill that counters the force of the

If yours are commercial ham "thrust bearings" they aren't. Rather an angular contact bearing which can handle some combination of thrust and radial loads depending on the design. It takes a mighty la

Great answer Scott. I would just like to add with some rotators such as a K7NV Prop Pitch, it is recommended to have the full weight on the rotator. John KK9A Probably one or the other, not both. Tha

In my current (about to be replaced) installation I put all of the dead weight on the thrust bearing thinking I was saving the rotator. I had heard in the intervening 20 year period that loading the
