Need a bearing, not sure what to ask for

Bret4207 · Dec 2, 2020

I need what I'd call a pillow block type bearing for a horizontal shaft, but I can't use a self centering type. I need something that is more like a solid bushing type of thing that would work to support the 3 "U" joints in the power line. This is for the PTO for a dump box trailer I am tol was built from a 1938 Federal dump truck. The original set up disappeared years ago and the hardwood block "bearing" gave up the ghost on me. What do I look for? I suppose I could use a bushing in a pillow type block too, but I can't find those either. Thanks!

Take the parts to a bearing supply house. If they can't find a number on it somewhere and cross ref. they can "mike" it and get you something that fits.

I don't think there are many bearing houses that can match up wooden bearing blocks, that were likely home made.------------------Loren

OOps, missed a pertinent detail again.....shucks. Grin

measure the shaft and go to a brg. house and tell them what you are needing. its the same principle that some grain augers use on the shaft.
would be like a brg. shaft support. i know what u are talking about. even a brass bushing bushing works on them . just keep it greased. even
the farmall 560 has those on the steering shaft.

The split housing ball bearings shown here can be shimmed to rigid when assembled. This would allow the mount to accomodate the shaft, then be solid.

Not sure what your shaft diameter is, but maybe a hanger bearing from a heavy truck might work? Don't know, just
thinking out loud.

Maybe this doesn't apply, but the fleet I worked for had PTO's on almost everything, the PTO on the transmission and the pump near the back of the truck, what a mess of shafts and u-
joints. We started relocating the pumps near the PTO and running hoses to the rear. Eliminated most u-joints, worked for us.

two bolt pillow block bearing,, use them all the time on drives, there is also a 4 bolt flange bearing same type self-aligning bearing just for horizontal four bolt mounting

VicS · Dec 2, 2020

I would think a self centering pillow
block bearing is what you need. U-joints
need to move in and out a little. Also
need to be timed. All the same. With 3
joints just need to hold longest shaft up.
If other joints are pined.

My fathers dump truck had a long shaft going back to the pump, and it was whipping a little and sounded bad. We were afraid it would fly out at higher speeds. I made a wooden bearing with a grease zerk in it, worked until dad passed away, but it didn't get a lot of hours, we sold the truck at the auction, it was still working fine.

1958 -2002 Chevy autos used a 2 piece driveshaft and they used a center hanger bearing. They are available at Speedway
motors Lincoln Nebraska for 12.99. This might work for you. Working at the local Chevy garage in the early sixtys and
replaced quite a few of these. Being a part-time high school kid I always got the dirty jobs!

Bret4207 · Dec 3, 2020

Well, thanks for trying guys. Janicolson came closest to what I need I guess. Can't use a self centering bearing because there are 2 U joints behind the bearing, 1 ahead of it, plus the u joint at the PTO attachment end and the trailer is pined to the tractor draw bar. Way too much movement and the self centering bearing allows things to go cattywumpus. I may make up another hardwood block but line it with a metal bushing if I can't find something locally. It's a 1" shaft, so it's not a high HP application.

Take two 4-bolt flange-style pillow block beatings and mount them back-to-back with a pieces of flat steel between them to mount and support them.

Obviously, the support piece will have to have a large hole for the shaft to pass through and 4 smaller holes made in it to attach the blocks.

I guess you wanted what I call a carrier type bearing then,, used on drivelines,, I must have missed you had three u-joints, my Dodge grain truck has a couple of the greaseable bronze type ones in it,, I need to read posts better before sounding off sorry about that

Bret4207 · Dec 3, 2020

No problem. Something like a carrier bearing is pretty much what I need, something that keeps the shaft lined up. The self centering swivel around and with the u joints it ends up in a mess.

DUNNO exactly what a "carrier bearing" is, reading between the lines I think some of the posters are talking about a "hanger bearing" for a truck driveshaft.

Typically, those are mounted in a (very) flexible rubber "donut" which isn't going to meet your needs (IF I understand exactly what you are doing).

For a more rigid support that will keep things from flailing around, may I suggest you read and reconsider my previous reply?

"Carrier bearing" was what I grew up calling them and understood that to be the nomenclature in the parts book. Yes, your suggestion of 2 bearings would work if there was room for them. I'd have to fab up a whole new mount to use 4 hole flange bearings. 2 self centering bearings in pillow blocks would also work if there was room. There isn't room. I think I'm going to just make a bushing if I can't find a mounted one of some sort somewhere. But thanks for the suggestions, I probably should have taken a pic so folks would get the layout easier.

yes some are mounted in rubber the ones I am speaking of for that app are solid mounted and can have either a ball bearing or bronze, I sold parts in a industrial warehouse for years,, I might have a clue, there are a lot more types of a carrier bearing than on a pickup or truck style,, I know better than to comment on this page some day i will learn to let the REAL experts answer

Yupper! There's a zillion "experty experts" out there ready to pounce on people that might actually have a clue. Gets irritating sometimes, but most of them are well meaning...I think.
