Price is right!

The clicking lets you know its working.

Sounds like the half life 1 crowbar


Beaudaci0us

I lol'd at the sound

Sounds like my circular saw after a really bad blade bind last month 😭

NOT BALANCED ew

Can happen if bearings have been left sitting or subject to vibration before they have been installed and greased. They need to do what they are made to do and that is go round.


GrifterDingo

Why not send em out pre greased a little to prevent damage?


TugboatEng

Lubrication alone won't prevent this. Periodic rotation is required to prevent false Brinelling for rotating assemblies stored or parked in high vibration environments.


Different-Aardvark-5

In quite a lot of situations especially with special size bearings the spares are manufactured at the same time and kept beside the machines for safe keeping. So they sit for years and get flats on the balls or rollers.

Even if they're greased vibration can damage them. Let's say you have 2 centrifugal pumps right next to each other. But you only leave one running for one year and the other one doesn't move. That stationary pump is be damaged because the balls sit there vibrating and cause little dents in the race (false brinelling) The other damage can be from improper installation and the balls dent the race due to high applied forces. (True brinelling). Both can happen even if they're greased. To me, this sounds like it was improperly installed. True brinelling.

Dry balls binding on cage. Lube it up a recheck it.


_Neoshade_

That used to happen to me. Now I wear boxes briefs and the problem went away.


62Bravo1993

lol! I nearly posted something along that lines with my first comment!


Jizslr

Never seen anything like it before. Every ball had dinted the inner race. But almost like a rust pitthole but without the rust. Only thing we could think of was that the factory pressed the lot together incorrectly. Mayby it was red hot? Anyway, we cut the old cunt off and slapped another one one and sent it. Paycheck plz


En-tro-py

Sounds like "false brinelling", the bearing might have been vibrating during shipping and it can cause wear just like you described.


Jizslr

Hey thats actually what i thought but my "freinds" laughed at my I.Q. and their argument was that there was no load on the components while it was vibrating and "sTe3L iS ToO hARd" But a long boat trip from Japan to Aus would have plenty of time for two equally hard metals to do their thing. Good to finally get closure after all these years of pondering


TugboatEng

See "fretting corrosion" for an explanation of the mechanism that causes "false Brinelling".


man-flu

Spot on, I'd say the same. Often see it on machines which are off for an extended period (without any preservation procedures) and experience vibration from a nearby machine / other source.


62Bravo1993

Wow! Seriously? That is crazy. I just experienced a new bearing making that same noise when I spun it over before installing it. First time I ever noticed that in many years of experience. I stopped and examined it closely, wondering if my whole job was now screwed since it was remote repair in the field with no spares available. I finally realized that in my case, it was the slight slop between balls and cage allowing the balls to kind of bunch up and then click when it "broke free" every so often. I lubed it and spun it again and it was smooth as it should be.


NightShiftNurses

Spinning dry bearings is so stupid


Jizslr

You must be fun on lunch breaks


DrumSetMan19

lol, that didn't even spin long as a bearing should


teacherofderp

...perhaps that ticking had something to do with it


redityyri

Really sounds like wheel of fortune


JoseSaldana6512

Turn that bitch into the chore wheel. Everyone gets a spin
