Topic tags/keywords: tablesaw bearings ridgid 4511

Has anybody else with a Ridgid 4511 experienced arbor bearing failure.

My problems started about 3 weeks ago when I noticed a different noise coming from the saw. It first showed up when using a full stack of dado blades. It sounded like a rough bearing, changing frequency, and even a little chirping. The saw also seemed to have a little difficulty cutting through a 2 by. I kept my ears on it, didn’t use it a lot, but enough to finish a small project.

I took the blade off and cleaned the saw completely. Turned the saw on, without the blade, and it sounded rough, though a lot different without the blade. I called an engineer friend over to see what he thought of it. First thing we did was remove the belt and run the motor by itself. It purred like a kitten. You could tell by turning the arbor by hand that the 2 arbor bearings were a problem.

He was game to dig into it so we had the arbor carrier off in about 20 minutes and it was real clear that the bearings were bad. We popped the bearings out of the race and examined closely. They basically were running dry. It sounded like there was no lubricant in either bearing. They were bearing# 6004-z. Looking in the saw’s parts manual and at Ridgid’s site, the bearing spec is 6004-zz. A z model bearing has one metal shield, a zz bearing has two metal shields. It appears to me they put the wrong bearings in my saw.

The saw is regestered under the lifetime warranty, so I’ll call them tomorrow to see if they will mail the bearings to me. In any event the bearing is a very generic model and costs little (about $6 per). I’ll order and change out the serpentine belt at the same time.

I was just curious if anyone else had a problem with their Ridgid 4511 arbor bearings.

Update – I got a hold of Ridgid’s authorized repair center – Ed at Allen’s Tool Repair in Billings Montana, about 125 miles from where I live. He was familiar with the saw and had the right parts. Mailed them that day and I got them the next. I asked about which bearing should be used and he said that Ridgid used a shielded bearing to save a few bucks. But he sent sealed bearings which should last much better. Now I have to get them put back in.

Final Resolution- I recieved the sealed bearings from Allen’s the next day. They went in without a problem and the saw again sings while passing the nickel test.

One note though. Not knowing how long it would take, I had ordered replacement bearings from Gardner which is where the Ridgid web site directed me. They sent shielded bearings, it took 10 days, and one of the bearings was froze, obviously someone elses defective part. When contacted, Gardner readily agreed to send a replacement, though I don’t know if it will be any faster than the 10 days. Not the greatest of service but anybody can make a mistake.

I owned that saw for 2 years and used it in our small cabinet shop before selling it on CL. I had to spray white lithium. Grease into bearings every 2 weeks. We never ran a dado on the saw. I personally was not happy with that saw. But we bought it new for 300, used it 2 years then sold it for 350. So cannot complain to much.

I’ve not had any problem with mine. Sounds like the first time I turned it on.

Glad you figured it out and fixed it so easily. My Craftsman saw is a 1996 and I dread the day I have to change the bearings. Not sure I’ even know where to start.

Just make sure the bearing is lubed and it should be fine. We use our saws a bit more then your average bear.

I have the 3650, trouble free since 2006.
My bud had the 4511 and he said he had the same trouble with his. He got bearings through fastenal for about 15 bucks. Been Ok since changing them out.

I restored a used 4511. The arbor bearings were bad due to weather and abuse. New bearings run great. Not sure about the z versus zz thing.
