I have done that back in the 70s to fit bearings on the shaft of trains. We had a 500 litters metal barrel about 2 meters diameter. Fill with oil, heat it up, fit the bearing in the box and drop the whole thing in the oil. Wait to expand, get a crane to lift the box and insert it into the shaft. Your video made me go back 50 years ago, thanks for sharing.
I have an old Convection Toaster Oven that I paid $5.00 for at a Goodwill Thrift Store about 30 years ago and that is all it has been used for since I bought it. Sure beat paying $600.00 at the time for an Inductive Bearing Heater to do the same job. I have had a few helpers over the years who have placed their meals in it and then complained that their food had an odd taste to it though, LOL
Just did something similar last week with a press on reluctor. Heated that bad boy with a propane torch and it dropped right on just like the video. I like the idea of the oil method for a bearing though. Any reason why not just use a press here? May have been faster than waiting for the oil to heat up.
Hi, it doesn't take too long to heat, plus when there are several bearings to install at a time, it really saves time. It's also so satisfying to see it seat perfectly, instantly. And while it was heating, i had plenty of other operations to do for this job. Cheers!
Not at all at 275F. Years ago I got distracted and left it on high and a bearing turned blue at 400...Some service manuals will tell you to heat certain bearings in an oven to higher temps. The oil method is nice because the lubrication also helps it go into place.
It's called an interference or pres fit. The allowance per inch of diameter usually ranges from 0.001 to 0.0025 inches. Meaning the diameter of the bearing is smaller than the shaft that it is installed on.
Brilliant job, and I thank you for the video. Another technique, use a microwave oven with the bearing wrapped in a wet cloth. I don't eat anything cooked in a microwave, only used for heating non food items epoxies, bearings etc.
Just sharing some knowledge that may save you a headache. 250 is rule of thumb. ask skf koyo ntn they all say 250 max except high heat ceramic specialties especially on roller bearings. So may want to go down a bit i go 240 and have had to just barely tap on inner once or twice barely with tightest clearance schedule. Big pumps big motors
00:48 Hey doctor, doctor, what kind of antique disease is fährenhuit??? :-// I hope it´s nothing contagious????? Thanks for the cure anyway - THUMBS UP! ;-)
I'm an idiot. I'm using the junk toaster oven to do the same thing, but I forgot to use the fancy thermometer I bought years ago because it was "cool" to have. Idiot.... No wonder the bearings just dropped 1/2 way. they weren't fully expanded.
But what does it say? “The word is near you, in your mouth and in your heart” (that is, the word of faith which we preach): 9 that if you confess with your mouth the Lord Yeshua ישוע (Jesus) and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation. 11 For the Scripture says, “Whoever believes on Him will not be put to shame.” 12 For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him. 13 For “whoever calls on the name of the YHVH יהוה (LORD) shall be saved.” Romans 10:1-13

We used that trick on semi transmissions in community college! Just found your channel liked subscribed and rang the bell!
Thanks!

Well done, sir. Well done. 👍🏻
Hello, thank you for your technique, by the way, what is the temperature for the oil thank you
275 degrees F.

Nice I'll have to use that trick
Good day does'nt that heat hurt the bearings? good idea. Thanks

Do you have a neat trick for removing them?
What type of bearing is this or the name of it? Great video of that trick on here. Great idea.
This bearing is conical. They work in pairs to provide axial and radial load bearing.
This bearing heating techniques can be useful into Machine tools spindle bearings installation ?
Does it will affect on spindle runout ?
It should work well.
Absolutely the best way to properly install a bearing.
The worst way is to pound on it.
Is the hydraulic oil safe to use on a pinion gear bearing that goes in a sports car differential?
absolutely!
Or, throw the other side in a deep freeze
I need a bearing heater
Thanks for sharing!
Let me know the tolerance between shaft n Bearing
It's called an interference or pres fit. The allowance per inch of diameter usually ranges from 0.001 to 0.0025 inches. Meaning the diameter of the bearing is smaller than the shaft that it is installed on.
I work for Koyo, if you gotta do that it’s a shitty bearing.
Hi! It has always been suggested by the manufacturer to heat certain bearings. They used to use a small oven, but this works better.

What about hot oil? Does it affect material properties?
No..not at 275 degrees Fahrenheit.

What kind of oil?
I use International Harvester Hy-Tran, but any hydraulic oil will do the job!
@@FarmallDoctor Would motor oil work? Thank you for the video!
@@jackiel9054 Yep! Engine oil will work just fine.

Haha! Very funny.. Lol
Which oil are you used
Hydraulic oil
Haha good one
Where can I find these?
It's just a cooking Wok. I bought it at a thrift store for $5.00. They sell them new as well at any major store.
Farmall Doctor How much
Farmall Doctor Also where can I buy a heater?

I don't think you know what you're doing you need to press that bearing in with the hydraulic pressure
Unprofessional use of pliers
How so?
@@FarmallDoctor Hardened teeth of pliers could damage bearing cage and pliers only on one side of the bearing can jam up inner bearing ring before rested on the shaft completely.
@@9traktor I haven't noticed this to be an issue. It's not like I'm double handing the pliers as tight as I can.. haha.
@@FarmallDoctor The Doctor is IN!!! :)
Can these bearings be removed with a hydraulic puller?
Because i know once they cool they don't come off unless you cut them
Yes.
