How To Remove Pillow Block Bearing From Shaft

Pillow block bearing puller
Tin can anyone recommend a puller that works well for pillow cake bearings? I take several 2 jaw and 3 jaw pullers, but none seem to work well on pillow cake bearings....

If you lot employ two small cutting hammers you tin can usually smash the external bandage iron housing off the actual bearing then employ a standard puller to remove the bearing.
Some other option is to utilise a 4 1/two" angle grinder to divide the whole housing and begetting down to the shaft and so only slide the remains off the shaft.

If the bearing is stuck on the shaft, I've ever notched it with a grinder. Quick, clean and easy.

I've done both of they above, but idea there might be a puller defended to the chore. Grinder is a cumbersome option in facilities that require burn down permits or where occupants are sensitive to the smell...simply if at that place'due south nada else out there, guess I'll stick with cutting them off. Btw...what is a "cut hammer"?

Then use a wide flat screwdriver or chisel & hammer to carve up the housing.Eric

I clean up the shaft on both sides of the pillow cake,real adept. And so I put a length of blk pipe over the shaft ,up to the bearing and hammer the bearing back a few inches,clean the shaft where the begetting was and so the onetime bearing slides right off the shaft.

I only spent 6 hours getting a 3" pillow cake bearing off a shaft. I couldn't just cut it because it was up confronting the bracing so I had to pull it a couple of inches. I bankrupt the casing off and then sheared a class 8 bolt on the puller and finally got information technology to motility to where I could cut it. The shaft was badly fetted so ended upwardly replacing it also.

- That'due south my method with condenser fan blades and it always works. Tried it last calendar week with a begetting and got into a cluster F where the bearing was pushed into an area I couldn't cut information technology with grinder...won't try once again. Originally Posted by TechmanTerry

Or a cut torch. For those that empathise oestrus transfer and how a cutting torch works.
Got a pretty proficient story near how I showed a former employer how to do that. Remind me afterwards. Information technology would take a bit to blazon information technology all out, and go the grey matter working correctly. Starting to get the drinks going, and getting dinner together . . .
Seems every few years I burn a bearing off.

That'due south a fob that works very good. The thought being to get the bearing on a clean piece of shaft, and so clean where it was, then slide it off.
I learned that play a trick on from a tech I had piffling respect for. I had to give him more respect after I saw him do that.

Servicerunner,something lost in translation. Doing the make clean/slide/clean/slide method does not involve cutting,or grinding.That a diff story. I do it that mode also ,only sometimes.

A cutting hammer is a minor short-handled 'sledge-esque' hammer with a two-iii lb. head. Originally intended for utilize with a stone chisel for cut / shaping rock, for boring holes in stone with a star-drill, and for 'feather & wedge' slab cutting. They are available now in 1 piece with a metal handle but whatsoever cutter with his cocky respect intact would only employ a wood handled cutting hammer in my opinion.
My suggestion was based on either smacking the pillow block from contrary directions at the same time - which takes a bit of artistry to become only right - or to 'dorsum-upwards' with ane cut hammer held firm confronting i side of the bandage fe housing while you smack the other side with authority with the other cutting hammer.
A cutting hammer is not really a sledge hammer (the smallest "sledge" hammer is iv lb. anyway - even with a short-handle) although the terms are now used interchangeably so far equally I tin can tell. It is a pity that and then few workmen seem to know the proper names for things now - or even intendance to it seems.
Still; at present You are 1 less. <g>

- Nobody calls them "cut hammers" anymore, apparently. They take "rock masons" hammers that also have a wedge-shape on the opposite side of the sledge-manner end, just the hammer that I have is chosen an "engineer's hammer" which looks like a small sledge hammer but only weighs 2 lbs or then.

It is a pity that so few workmen seem to know the proper names for things now - or even intendance to it seems.
However; now You lot are one less. <thou>

- Sorry, should have said that's what I tried to do (button bearing dorsum, clean shaft, and so slide off). What happened was that it was a tight space and when I pushed it dorsum and cleaned shaft I still couldn't go it off. And I had pushed information technology into an area that I could no longer go the grinder on it. Originally Posted by TechmanTerry

Here'south one you might like. Many years agone, had a reckoner room with bunch of upright air handlers in a row with bearings that needed to be changed. Made this bearing puller that worked totally awesome.
The photo below is on a different air handler. But I've used that puller a lot. And it works peachy. Takes a bit to setup, but and then you just crank on the all-thread basics until the bearing breaks loose. Yeah, yep, I know . . . The rest of you lot like to sweat when pulling bearings . . .

Something else you tin practice is to make clean the shaft behind the begetting and then knock the bearing in onto the cleaned area.
So clean the shaft out to the end and slide the new bearing on. Leave the erstwhile bearing in there.

The photograph below is on a dissimilar air handler. But I've used that puller a lot. And it works cracking.

Aye, made completely from scratch.
I paint my tools yellow to differentiate them from visitor tools.
Bought some iv" round stock and so paid a machinist to make it wait pretty. If I had to do the same thing today, I might do it all myself. Just in the case of that task, I asked the customer if he wanted to human foot the neb to take that made, or pay a lot more for my labor to dick around and not get annihilation done.
