inner bearings question

[tonyk72]

I got some new bearings from Buffalo Bearings and they don't exactly look like my old ones. The part # on the new one is SA206-20G. Will these work? They are HBC brand. My old one is Peer. The new one is on the right...and whats with the little nipple on it?

The little nipple on the one on the right is a locator tab. You need to remove it. Grab a set of wire cutters and firmly grab it with them and pry it out and throw it away. If you cannot get it out you can use a dremel tool and grind it down til it is smooth. Make sure to pre-grease the bearings with a needle adapter.

What is the purpose of the tab and if it does not interfere with mounting the bearing does it still need to be removed?

leave that nipple their so when you line up the zerk fitting and crush the flanges together
the bearing will not try and spin in the flanges...does that make sense

It's best to remove it. The bearing will not fit properly in between the flanges when you press them together. The small space at the zerg on the flange is for the grease hole on the bearing to line up to. If you leave it in and stick the bearing nipple in that gap, grease will not be able to get into the bearing. Even the online Argo service manual shows the bearing grease hole lined up to the zerg. When you torque down the flange bolts it will firmly grab the bearing's outer race and it will not spin in the flanges.

Two opposing opinions, anyone else have any thoughts about removing or leaving the locator pin?

[Mike]

I always remove it.

[fmints]

I removed mine also.

well some people like peanut butter and some people dont

[jstout9]

I guess what I'm saying is. It has to be there for a reason. And if you remove it, does it create a void inside the race that may cause damage to the roller balls?

true.. And I do love peanut butter

Some pillow blocks have slots for the locating pin, your flanges do not. Removing the pin does not cause any damage and the remaining hole will be in between the flanges, protected from the elements just as your main grease port in the groove is.

I ended up removing the nipple too...I actually filed it down per Buffalo Bearings. It just didn't seem to fit right in between the flange halves. The bearing was also incorrect for my MAX IV. I ended up getting a 206 20 R3. I would have snapped a pic, but it looks similar to my old one.

I remove it on all mine. I seem to remember that when I replace the bearings in my Max IV last year all the bearings the previous owner had also removed it from the ones he installed.

You might just call RI and ask for Jay (Parts). He's been real good about answering my questions, or having one of the other employees get on-line and help. So far they've been real helpful even for parts (like bearings) that I haven't purchased from them. On the other hand, I know most of the employees there by voice because I seem to break a lot of parts and have to call them a lot.
