Question: Can this be used for a 36 inch diameter turntable? If not then what is the ideal sized bearing that I should buy?
Document: I used this for a 30 inch lazy Susan that I made and I really like it. Great price, and quality.
I had a particular situation that needed to spin a cash register around. three of them in fact. I found this roller bearing lazy sue and it fit the bill. These units have been in use now for several years and still going strong. Buy 'em.
We've had this for about 8 months, and are using it as a turntable for airbrushing custom cakes. It hasn't given us any problems despite being on a cabinet on our back porch and exposed to occasional blowing rain. I would buy another again if we ever need one.
The 12 inch Lazy Susan makes a loud rattling noise, even after lubricating. I thought about returning it, but decided that it was not worth the time and simply threw it away.
Easy to install. Sturdy construction. Never binds up. Great for custom storage upgrades. I used mine for making Lazy Suzan platforms inside a corner cabinet.
It rolled pretty smooth the whole night. Looking down in it, it seems there is a light coating of grease included on the bearings, though just a touch noisy. Ultimately, I think I will make a dedicated table with a revolving center using this bearing as I have good faith that this thing is solid and will last a long time.
Why don't you lubricate them in the factory. Or, better yet, use sealed bearings. Oh, BTW, the bearings are in a 2"-deep slot, so you'll be needing a straw. Without lubing, the bearing turns very rough.The cryptic instructions I can forgive. **6-MONTH UPDATE**The bearing have seized up. This lives inside a cupboard with 100 lbs of cans on it, so replacing it is a pain. I'm demoting them to 1 star.
A downside is no screws provided. I glanced at the directions, but it wasn't hard to figure out for yourself.I went to the local hardware store and bought a 23.75" round wooden platform. I brought it home, found center, drew a 12" circle, and threw this on. I Found 4x screws I had laying around and attached through the provided hole on the bottom of the bearing.
Straight out of the package it wouldn't turn at all. I tried greasing the ball bearings and sliding it but could hardly get it to move. When I looked inside the bearings were all jumbled up and the more I tried to move it the worse it got and eventually bearings started to fall out. Hopefully I was just the unlucky one and got a bad mechanism. Buy with caution.
We use these with a granite turntable. Because of their weight capacity they can easily stand up to a 24&#34; wide circular slab.
Answer: If your load is balanced then it might be ok.
