Badly worn # 80 chain link

Got this baler and rolled 2 1/2 bales and the chain broke. Guy said it put this new chain on last year and did almost 300 bales. Anyone ever seen this happen? The rest of the links seem normal.

ar for the course if it Chinese chain.
 
Yup had it happen on my vermeer 605G. It has a drip oiler for the chain that wasn't working, replaced chain and fixed oiler no more trouble.
 
I have a couple of balers that have baled thousands of bales and the chain isn't even close to being worn like that and I worked in an industrial plant with lots of roller chains under severe conditions and it takes a lot of use for a chain link to wear that much.I'd say he misspoke it wasn't last year it was last century.
 
I'm going to say defects in materials or workmanship. Reason is what you said about the rest of the links appearing to be OK and the stark difference between the two links posted in the picture. If it were a wear problem all would show some of it. I got mine at TSC if you don't have a source. Seems Every time I buy a baler the chain is rusted out and the baler shows evidence of chain breakage, especially on green ones.
 
There are many things around here that I try to cheapshot as possible, but two things I refuse to cheapen are bearings and chain. I'll steer clear of ANYTHING that has made in chin a on it on both. J A Pan is bad enough, but the red stuff is way too much trouble for as long as it lasts.....
 
Well if it is cheap chain and a worn sprocket then 300 bales could easily wear the chain that much.

I only use Diamond chain on my round balers. It will out last the cheap(China) chain two to three times as long. Plus a worn chain is terrible about wearing out sprockets.
 
I agree with Texasmark1, a defect will do just that. I worked in a chrome factory and seeing all the defects in the shafts that we had to cut out made me realize why some don't last as long. The defects in the shafts looked like a knot in a piece of wood, then when chromed it put a dimple in that spot.
 
A drip oiler may help as been mentioned. This heavy field dynamometer was chain driven and we made sure the chain oiler was working as those chains were a pain to change. Hal
PS: The trailers were chain drive too.

Vermeer baler I see?

Once, and it can be a defect.

Happens again, have to look into alignments of sprockets, that idler tends to wear and deflect the chain, worn sprockets, and so forth.

If rest of chain is good, press out a pair of links and put a splice in, good to go.

Does the wear pattern on the next roller back look off center or is it the camera angle and reflection that just makes it look that way.
