How to remove this ball bearing?

[jd5000]

I want to replace this bearing (it is an SKF if that matters). As you can see in the images, there is some kind of metal washer/sleeve pressed up behind the bearing. I took a screwdriver and was able to bend the edges back away from the bearing slightly, but it is not moving. If it was not there I could just pull it off the bearing with my bearing puller, but how do I remove the bearing with this on there without damaging it (it needs to go back with the new bearing?

Use the same number of bearing with an RS metal seal.
Scrap the existing bearing and metal seal.
RS means that ONE side of the bearing has a metal seal that is integrted in the bearing and totally dust and water proof from that side.
Or use a 2RS which is sealed from both sides and lubricated for life.

Cut the bearing

Heat the bearing, Tap it off the shaft.

Bearing separator puller will do it.

It is a washer.
Why are you bending it with a screwdriver ? ? ?

If you have a shop press, use a bearing splitter and press it off. If you don't have a press, just cut the outer race off, put a heavy cut into (but not through) the inner race about 45 degrees off parallel to the shaft axis, support the bottom side of the race, and split it with a chisel.

Edit: this comment got a few likes but I want to clarify that you should have a narrow kerf and a thick chisel so that the downward strike of the chisel applies outward pressure to the inner bearing race, causing it to split at the cut. You're not trying to chisel through the race. It is hardened and you will probably ruin your chisel.

RS is rubber shield. Z is metal shield. 2RS or 2Z is both sides shielded.

That metal washer thing isn't part of the bearing, have you tried pulling everything off the shaft at the same time?

Looks like that may be a locking collar bearing. Usually they will have one set screw and a divit you can use a hammer and punch to unlock the collar from the bearing.

Just use a 3 jaw puller or a press if you have one.

 

[jar944]

You can't move the washer because it's pressed between the inner race and the flange. pull/press against the washer.

An Angle Grinder, Sharp Cold Chisel and a BF Hammer are your friends when a bearing needs to be removed from a Shaft.

A bearing seprater is the tool you are looking for to remove the bearing.

Note the bearing is most likely an interference fitted to the shaft. What that means is the shaft is a few thousands of an inch larger than the hole in the bearing. When you go to install the new bearing, you should put the shaft in the freezer for a few hours(-20F) and heat the bearing (100-150F) on an incandescent light bulb for a few minutes. This makes the shaft small enough to fit in the now larger hole when they are the same temp the bearing is locked in place.

908Jim and nadogail have the answer if you have a die grinder w/ 3-4 inch cutoff wheel. I have done many automotive bearings that way.

Serious question..

Why are some of you cutting bearings off?

I can possibly understand if you can't get a puller to the location or can't move the part to a press but otherwise?

Not every bearing survives a puller or splitter, especially if you're stuck pulling/pressing the outer race only. I've seen plenty of bearing cages fail causing the outer race to pop off leaving a firmly seized inner race on a shaft against a surface without any sort of lip for a puller or splitter so cutting the inner race off is your only remaining option. It gets worse if you're working on something that was never intended to be serviced at the bearing level.

Try to pull it all off together. If that doesn't work cut it off with a grinder or torch. Torch would be a last resort for cutting something that small.

I have to disagree about the torch, we did it all the time using a torch. comes right out.

I've done it with bigger bearings no problems but it seems like on small ones I have a hard time not cutting into the shaft.
