Got a job of rebuilding a gearbox off a New Holland type 56 hay rake that was made long ago (pre 1970 by the looks of it)..Looks like they decided to use a non standard bearing in it...deep groove ball bearing ID 1.250 OD 2.500.

I cannot find it listed anywhere online, quite annoying when engineers decide to build things using non standard bearings.....One of my lathes is the same, it uses a flanged Timken roller bearing for the main spindle that is no longer available in a flanged variant..

Why do engineers like to use non standard bearing sizes??????

so you have to buy the spares off the company who made the machines, at inflated prices ..

the autotrade does it a lot .

May be it was plenty standard when made. Most bearings now are metric, at least the ones I have run into. Gary P. Hansen

Tell me about it!
Had one a while ago with an NTN number on it and had one hell of a time getting one...even though I had the damn NTN number. Not listed in the NTN catalog, no cross reference from any body's catalog!
Nobody could match one up dimensionally. It's like it didn't exist.
Finally talked to a good local bearing supply guy who pulled a one out of a special drawer for $70.
Oh yeah, local OEM had lots, for a little over $400 each!:eek:

Can you bore the housing to fit these:

I need the thickness but I think it is a
1654 ZZ - 2 metal sheilds
2RS --- 2 rubber seals

1654 Bore 1.250"
OD 2.500"

Should be able to get at any good bearing shop

Thanks for that motor works, I think the original number should be XLJ 1-1/4 but it is worn off the bearing...The modern XLJ series start at XLJ 1-3/8

Just a tip:

Bookmark Peer bearings and look there first for odd bearings in inches
They have a good listing of odd stuff.
ex 6204-3/4", 6205-1" ,6203-5/8", 1600, and "R" types etc.

Their quality was never great, but
that may improve now that they are owned by SKF.

HAHAHAHA ...
Non-standard bearings, yep.
When I 'inherited' a beat-up old chinese vise, I had to replace the bearing near the handle.
Yeah Right.
The O.D. was metric, and the I.D. was 1 inch. ?????:confused:
What the He...???
My solution was to turn a bronze bearing.:)

Kidd,

That is not all that uncommon. There is a whole series of electric motor berrings that have inch ID and metric OD. This is a special case due to the common inch size shafts used in American electric motors.
