SAF / Split Blocks: Features, Installation & Maintenance
PTI Features Installation Maintenance
3 components to the assembly:
1. Housing - with 2 seals, fixing ring
2. Spherical Bearing
3. Adapter Sleeve - including Lock Washer and Nut
This video reviews the features of the housing (pry slot, oil relief channel, solid base, etc.), how to measure the internal clearance, fixed vs. float bearings, and mounting the assembly to the shaft. We'll also show how to make final adjustments and review installation tips.

Well explained, it makes a lot of sense, I didn't know about clearance part at all.
Thank you sir, the video explained the installation very well.
It's really helpful to use, how the parts were going to be place and where it will been installed...you just clear my doubt with single video...Tq ❤
thanks lot to share this kind of practical video, we expect more. ..
Thank you so much for the important and helpful video
very good Assembling techniques and servicing .
its very informative video.... very nice explained. every body can easily understand. thank u so much making such a video
Very informative and nicely explained. Thank you so very much. Namaste....
I can only understand some parts, it is professional works. I'm from China. This engineer is so great!
Very beautiful explanation .🙏
Excellent video. Thank you
perfect explanation...thank you
Great informative video Sir.. Thanks for the video!
For new engineers, in real life situations, the bearing is almost always assembled in the bearing housing and not dropped in after, although I wish it was. When assembling a bearing in its housing in a real life situation never take a reading with the feeler gauge in one place and lock off, turn the assembly every so often and take a measurement as you tighten, it will make a difference. Also when knocking the locking tab down, don’t drive it all the way home, ( it will be easier to lift it up later ). When greasing the bearing push it in from one side of the race until you see it coming through to the middle, then grease the other side. Great classroom video though.👍

A question about regreasing. Does a bearing housing like this, not filled full with grease, work as an (air) pump and still eject grease? Or does regular regreasing gradually fill up the housing up to a point that it is so full the grease cannot move anywhere but past the seals?
สุดยอดไปเลย ผมจะเรียนรู้ต่อไปครับ
Good job
goood video, thanks for the information
Hell yeah dude.
Awesome vedio.
Good explanation, it helped me a lot to change and check bearings and pillow blocks to change them, but I have a question, where can I find the specific measurements of the bearing set.
I’ve never tightened a bearing outside of the housing. While working on site it’s almost impossible to do so. Also for the floating bearing you have to make sure you account for the taper lock and the fact the bearing will move on the taper. Has to be almost pushed to one side in certain situations so the bearing has room for expansion side to side
Does the locknut positions (arrangement) in DE and NDE plummer blocks has any affect on bearing reliability. Should they be in opposite or same direction
Thanks dear sir
Thanks sir
This was an amazing video. Can we have one on lubrication maintenance? How much grease do you put in and how often?

Thank you very much.I think the fit between bush and shaft is too loose.You adjust the clearance and loose the nut.After that you slide the bush onto the shaft EASILY and this makes a contribution to premature failure.You can not tighten the nut more after putting the bush on its original position otherwise the clearance will be decreased.
Nice
Thanks for this video. I have just one comment on your clearance measurement that you should measure 3 points (3, 9 o’clock and 12 or 6 o’clock direction) and divide the sum by 2 to get a correct clearance. For more info, you can get it from p.52 of SKF bearing maintenance handbook.

thanks... if I don't have a feeler or I don't want use it, but I tighten the nut against the bearing by hand, how many turn I can tighten the nut more by the spanner wrench ? I have seen in a video that I need to turn it 120°, is that right?
Buen video, pero lo mejor para medir el juego interior , seria pasar la laina por los dos rodillos ya que se podria inclinar asi un solo lado y podria dar una medida equivocada

Hello a question the adapter sleeve should still move on the shaft after clearance has been done?
@MrSlpierce
Жыл бұрын
No, as you tighten the locking nut the sleeve grips the shaft and the bearing clearance decreases, so if you tighten the nut until you get the correct clearance by default the sleeve will be locked onto the shaft.
Having high axial vibration in sleeve mounted roller bearing drive end side of ID FAN.. WHAT should be done?
What is done as far as "re-greasing" is concerned? Does there need to be a grease relief port for online re-greasing in high speed applications? Or will it just push out through the labryinths?

90% ok, solo que el anclaje hay que hacerlo dentro de la cajera y en su posición de eje real. Una vez apretado, no se desliza por el eje. Tercera Ley de Newton. Si no se apreta bien en su sitio el eje se desplazara hacia la turbina. Si lo es, claro.
Why no any lock system for rotating side labyrinth seal?

Is it optimal to oil these bearings or use grease?

That’s going to depend on quite a few things, what kind of load, rpm, stuff like that. At my work, we have ones for arbors that we oil feed while running, and others on a grease schedule. Skf have a lot of good info on their site, not sure if they still send free info packets by mail or not, but you can get pdf files Freon them for free too.
We have a mill with Timken FSAF520 bearings. These use grease and not oil correct? A drain plug on bottom of housing has me wondering. Also, what's recommended greasing interval? I'm guessing every 8 hours.
@d4hoppy
Жыл бұрын
Mill's can either be grease or oil bath. Most housing will have the drains in them and just plug them in the event going with grease. Depending on the size of the mill normally larger mills, will be oil and smaller ones grease. Due the cost of adding a lube skid vs times needed greased a day.
for one side like tjis work temperature about 80 Celsius .. 24 Time work... how many grass we need?
Great explanation . Thank you But if we doing like this some times bearing getting heat up to 65 degree cent grade why ? Which thing will cause to raising temperature please Explain.

GADDAM JAIPAL REDDY overhearing is caused from several things but a few common issues we see are over greasing. Another very important thing to note that over tightening a bearing is almost always worse than under tightening. It causes the bearing to drag, which causes temps to skyrocket and premature bearing failure. Third but often common is bad alignment. Either the bearing housing is not square to bearing or shaft alignment is bad. That can cause high temps and failure too.
