Lazy Susan bearing noise

a possible solution

Bill Tindall, E.Tn.

I use them in my deer stands and indeed any I have bought are noisy. I oil them with transmission oil, I think it is 80/120 viscosity. It quiets the rattle.

I use Bostik bearing lubricant spray. Good for router bit bearings too. Lithium is too heavy and collects gunk. not cheap $13, but goes a long way.

The reason they are noisy is that the races are stamped sheet metal. Lube will help a little, a heavy load helps a little. A quiet bearing of that size costs hundreds and is vastly higher precision than you probably need.

I tend to agree with John about the construction of some these lazy Susan bearings. Some are better than others. I've got a 12" bearing at the base of my TV stand which is pretty quiet but, as John says, there's a lot of weight on it.

Possibly, the best you can do is try to mitigate the noise. If you've got the low-end style of bearing I'm thinking of, I wonder if you could fuse a black nylon rope in the channel around the bearing, unless the look would be wrong for your application. You could melt the ends and fuse in place.

correction and it works from practical experience

Not transmission oil.....differential oil. It has a big viscosity number, like 80 to 120. It is designed to stick to parts and it sticks to bearings in these

Lazy Susan things. I have 6 of them in service and none make noise any more.

I tip the device on edge and squirt in some of this thick oil into the race to make a puddle in the bottom of the race. Then slowly rotate the inner race to move the bearings through this oil puddle. When the bearings are covered they become quiet, even to a deer's ears.

This approach might not work for your application. This oil might have an odor that would be objectionable indoors. If over-oiled excess oil could seep out in some undesirable place. But it does work to quell the rattle sound of a new bearing.

Whatever you can come up with to coat the bearings to make them sticky will work. The sticky coating will slow the velocity of the bearings crashing into one another and damp the sound of them crashing into the race.

I tried veggie oil and it gummed up after a couple of years. Olive oil might have performed better as it is less prone to polymerizing. A heavy weight silicon oil would be perfect.

If it can be taken apart, I wonder how "space balls" would work?

They should be quiet if they will support the weight in your application.

Thanks for everyone's responses.

Wish me luck.
