Nut to Be Located and Babbitted in Place?

I don't know that I've ever see anybody do this. Here's babbit that you could use

Sort of odd loc-tite, eh? What kind of application?

Glad to see you posting.

What is the nut that will be babbitted in place?

Curious, sinec never came across this type of event.

I Know the nuts located/tightened and staked in place (break the threads by punching so that it does not try to disengage).

Instead of, "Nut to be located and babbitted in place?". What if you said," Nut to be located and soldered in place?"

Hi wingman.

Wingman needs to come back with more explanation. I suspect we are dealing with Chinese English versus American English.

Therefore, I will agree with Lynlynch that it is to be soldered in place after locating.

Hi Lehman57,

Unlike us, Wingman gets the weekends off. He always comes back.

My sense is the you would locate the nut and then attach it (babbitt it) so that you could later thread a bolt into it. But............................Who knows?

Some babbitt materials have (almost) the same composition as Sn/Pb solder.

The two don't go together. A nut is just well.....just a nut. Babbit is a soft low melting metal that is used to cast bearings. Babbit can take enormous loads due to it's great bearing surface.

I wonder if this is a babbitt formed nut. The bolt is babbited in and after colling, removed to leave a threaded holein the babbitt.

I would say babbitt is weak for this use, but for low torque uses it might be done.??

the other way is to make a babbit captive nut for some application, musg like soldering it...

Babbitted is a light lead that is used in a varity of mechnical assembly like a seal ring for cones on a rock crusher or use for bearing, due to it's lightness,if thats what your looking for good luck

Hi

Babbet is a lead based bearing mateial and this link shows the process.

I assume the bearing housing would have some nuts in the area where the babbet is poured and would be locked in place by it.

Actually this sounds like a clever way of locking a nut from loosening that found its origin in a time when mass produced hardened lockwashers were still in the future and the master mechanic in the shop had seen enough poor installations of locking pins and tabbed washers to decide a greater degree of reliability was needed for some situations of bolted joints.

Prior to 1930 or so any machinery maintenance facility would be set up to melt and pour babbitt bearings for either cylindrical oil lubricated journal bearings or linear bearings such as found in the crossheads of steam locomotives. So the capability to pour babbitt into a cavity around a tightened nut was there. I believe a perusal of the subject of babbitt in 19th century mechanical practice will disclose examples of it's use solely for retaining two parts together that might otherwise be impossible to mate. J.G.A. Meyer, "Modern Locomotive Construction", John Wiley and Sons, New York 1892, Page 151 describes a method of using babbitt to retain a glass plate with tapered edges in a shallow metal cavity with tapered walls.

As long as the equipment operating temperature was kept well below the melting point of the babbitt metal and the volume around the nut had proper locking features the nut would stay in place until a mechanic applied the heat of a blow torch to melt it away.

I can also see how using melted babbitt to cover over fasteners in machinery moving through a liquid like lubricating oil or say the impeller nut on a pump could be construed to improve efficiency slightly.

Hi Wingman 1985, After locating the nut, you are going to position it in that place. Babbitted here means secured in place. Any vibration should not alter the position of the nut.In otherwords it should not get loosened. Rangasamy

Thanks every one for your kind response. I prefer to define "Babbitted " as "secured' here.
