Fail to design or design to fail

[rumrocks]

Engineers designing locking collar bearings with the outer race grease hole on the wrong side for most applications. Has anyone tried grinding a groove in the race with an angle grinder.

It's a pain in the ass to change a greaseable bearing prematurely because by design you can't get grease into the bearing.

It's good for the share holders, but engineers need shop time, then maybe they would behave.

Are you talking about the beater bearing on a deere combine? The one that has started many fires because no matter how many times you think you have greased it ...you haven't.

Tried to explain it to a couple service managers...blank stares.

yes, that one.

[bucket]

yes, that one.

Pretty phucking stupid that they wouldn't issue a recall...


Mine was working fine...stopped, moved to another field and got an alarm ..no bearing left just the races.

I think I have changed 3 over the years...no one at deere would even acknowledge the issue.

The bearing on the pulley side is hard to check with belt tension on it, started a fire when that failed.

Could a guy cross the pillow blocks and see if you can get one with the opposite side greasable? We have one like that on an OLD orange Brandt swing auger. You have to go to a bearing shop to get the pillow block to match a new bearing, or you have to get a bearing with opposite side grease holes to fit into the old pillow block. The one's Brandt supplies are guaranteed to last just into next year.

Pillow blocks are all standard SAE.
Just order an SKF or some good quality that haven't gone to China.

We found same on PU front roller bearing, hole on wrong side? Replace beater one, don't recall hole location.

Replaced original Brandt "china bomb" main flighting bearing with a much better cast housing, Non china bearing. Second year we had it.

This particular bearing is held in place by two flanges, [one with a grease zerk], one on each to the side of the bearing that bolt to the side of the combine. To make this work you would have have the locking collar inside the combine right against the beater [ probably not doable ] and have the grease zerk outside or have the collar outside and the grease zerk lined up with the grease grove in the race but inside the combine, not practical. Simply put it's the wrong bearing.

Anybody notice the "new" fafnir bearings that have laser etching instead of stamping for #s? They dont even say where they're made except for on the sku printed on the box... 5 letters with the first being a C.

That seriously pisses me off! When I think fafnir, I think quality. If these things are the same quality as the rest of the chinese junk they'll sink their reputation! I'll GLADLY pay double for something made in Japan, Korea(the better half), europe, or N.A. I have yet to find a bearing that's *fun* to change.

Do you have that dorky little extension hose?

I am sure in the past in talking to my local bearing retailer different brands of greasable bearing have the hole in the outer race on opposite sides because he always asks which side it is greased on and this will dictate the brand of bearing I need..

If Deere made a motor vehicle there probably would have been a recall, but off road, it's not that important.

The first time I lost the beater bearing I took it back and told them it was the wrong bearing because it couldn't get grease...They said its all they had for a part number...I asked if they could find one that would work..the next time was the same thing ...but they just keep stocking that part.

I should have went to a bearing place to find the right type.

[shtferbrains]

I would assemble the flanges on the bearing an the bench and without any shaft and hold it in the vice. See if it will take grease as the flanges don't fit that close on the bearing surface.
If not modify till it will but try avoid cutting a slot across the race as it may cause it to split under load.

Hamloc suggestion is best but that bearing has odd inner race.
