Bearing brass

[Herm Williams]

I need to make a couple of bronze bushings 2 inch ID 1.9 in long. A friend gave me a bar of tiger brass (his title) he said that if I cut grease groves in it the life would be almost forever. The metal has circular stripes around it. My question, what is tiger brass and is good bearing material?

Herm, I have some SAE 660 that has that look to it.

Sounds like 660, which is the typical bearing brass for machining. No idea on the grease groove comment.

Sounds like 660 bearing bronze. It looks like this:

Oops, not sure where "brass" came from, I meant bronze. I've gathered quite a stock of that stuff from Enco while rebuilding my Rockwell lathe (which needed most every bushing replaced). Hey, at least it was a "b" word, and the "r" was right too. Gotta count for something, right?

I want to know how Evan manged to bend that piece

SAE 660 Bearing Bronze is good material . I use it to fix Vertical Turbine water pumps. I fixed my squirrel cage fan with it as well. The bearing still has the same shaft clearance that I made it to 3 years ago . It is a grease packed bearing/ bushing I give it couple of pumps of the grease gun every summer . I put two holes 180 apart and pump till clean grease comes out and recap . There is no seals on this application . I also turned a new shaft for it as well; tossed the old coldroll shaft and went for the good stuff . I had some bent 416 laying around turned it down to size . Straight as an arrow now .

A straight groove works well , but a helical groove is even better . This all depends on the quality of the grease and how much attention you really want to give it . If you cut a groove in the middle of the bearing is acts like a reservoir.

I can hang onto the bearing after it has been running for a while it does not get hot , which is good.

It isn't bent. This is though.

[Herm Williams]

That is it Evan, it looks just like your picture except it has straight sides.
Many thanks for all the help you all have provided.

Make one like that and stamp LCT on the bottom

[Mcostello]

Hay Evan, do you have another peice like that one, I could use some.

[Evan]

That's the only piece I have like that. I shudder to think what it would cost now. I've had that for years. I've been saving it for that special project, whatever that is. It won't be napkin rings.

[edit]

LCT???

Hello
What size piece do you need? I can check to see if more is available.
