bearing dimensions

[alantani]

here is a list of the bearings that i commonly use.  what's listed first are the dimensions, followed by the boca bearings part #, then the abec rating, then the cost rounded up to the nearest dollar.  tom hryniuk forwarded some interesting information on abec ratings.....

HI Alan, here is a link explaining ABEC tolerance:

http://www.mcmaster.com/library/20070314/60355KAC.pdf

You will notice that on the shaft diameter difference is .0001"(one ten thousandth of an inch).  For the O.D. (outside diameter) the difference is .0001" to .0002".  So you are looking at a difference of .0003" total deviation.  In my world, thats a lot.  In a reel that is more than likely plastic molded to a tolerance of +/-.010", at best, or machined to a tolerance of +/-.005", the price difference isn't worth it.  More important is the quality of bearings!   Just my two cents.....

Alan,

i just recently upgraded some bearings to a buddys diawa zillion. I have found that diawa baitcasters td, z, x, s, zillion, millionaire, alpha's, sol, pixy, fuego all take the bearings in size. 5x11x4, and 3x8x4

however the diawa steez takes bearing size 5x11x4, and 3x4x10

David

thanks for the info!

Hey alan,
   I have a few questions.... first is, are all Abec-3/5...bearincs created equal?  found a site selling packs of ten for 50-60 bucks vs.  bucks a piece on boca.

second is, i am having trouble finding the dimensions for all the different bearings each of  my reels have.. (trying to stock replacements for my reels) and i was hoping you could help.


reels:
penn 113 hlw
Daiwa Sealine 50 (highspeed and high torque)
Daiwa Saltist 50
Trinidad 30
Trinidad 40
Trinidad 50
Penn 555

Thanks
Marcus

hi, marcus!  yes, there can be considerable variability between designs and bearings, some are definitely better than others.  stick with abec-5 and you should be ok.  for individual sizes, i only have ones that are listed in the rebuild posts.  i do not have a separate list.  it would be a massive undertaking.

best to get a set of digital calipers and measure them.  dawn at smoothdrag.com has an excellent selection.  alan

I am looking to upgrade, or at least replace, spool bearings in four of my baitcasters. As I review the schematics of the four (Core 100MG, Curado 300DSV, Calcutta 100CTE-GT and Chronarch 100B) I am puzzled on the differences (if any?) of the spool bearings specified for each reel:
Calcutta 100CTE-GT - BNT0194
Chronarch 100B - BNT2927
Core 100MG - BNT3812 
Curado 300DSV - BNT0194
So we have three different part numbers for four reels but they are all 10X3X4 SMR103's. While I haven't pulled them all yet they "appear" to be metal shielded both sides. Do the different part numbers reflect different ABEC ratings? Or is Shimano just trying to confuse me?

[alantani]

these are just shimano part numbers and have nothing to do with the standard bearing part number used by abec.

[Nessie Hunter]

Bobby, I may be able to shed a little light on that.  
I probably work on more small reels then most. I know I do a ton of upgrades to Ceramic #7 spool bearings.......
Bass guys have a need for speed and bragging rights to how hot rodded their reels are!!
I have a Lot of bass anglers & Guides in my friend/customer list..

5 yrs ago almost all the reels had a long/full shaft that went from end cap to end cap..
Through the pinion gear.....
Almost all had 2 bearings @ 3x10x4 mm one at each end up to 700 size round reels...

But time marches on and they get more high tech each year...
The last 5 yrs have had a lot of innovation and Copy Cat-ing in bass size reels...

The reels with a short shaft (true freespool type) have 2 size bearings, the normal is a 3x10x4 at left plate and the short shaft has the second at rght end of spool/pinion,
the shaft has a shoulder and bearing is held in with a shaft pin (dreaded, hated pin)...  
That one is a 5x11x4 bearing to fit the larger Shaft Dia there..

You can tell by taking off the spool tension cap, if there is a T shaped plastic dead shaft (short) in it, instead of the end of the spool shaft.  The reel has the 2 diff size bearings & short spool shaft...
Or look at the particular schematic for that model....

Now some Shimano, Daiwa etc etc reels have a full length shaft that goes from end to end..  
BUT have a Pinion bearing also.  
This is again held at rght side of spool with that same dang hated shaft pin...
(the shaft pin also engages the pinion gear) 
So these reels actually have 3 spool bearings. 2 @ 3x10x4 & 1 @ 5x11x4...

Have to look at schematic or know the model..  
I suffer from CRS and have not got up to speed on which is which....

So now you have 2 diff size spool bearings..
 
Lets go one step further..  
The Core probably has a small Left side plate area, and takes a smaller bearing, 'I assume' (we all know what that means) that to keep some structural strength or less weight?? in a smaller size end cap/plate.?  
Left side Plate bearing = 3x8x4 for the smaller size end cap reels...

Total ~ we now have 3 Bearing sizes in the newer model & smaller size (bass) Low Profile & round reels.....
3x10x4 mm ~ 5x11x4 mm ~ 3x8x4 mm.............

No way for my low budget, CRS suffering self, to keep up with them....  
I need to make a list and keep it current...  
I often order bearings before I get the reels.  For quick turn around....
So I sort of need to know what size and how many they take..
A few years ago, I could get 3x10x4 for everything up to 700 size round reels --  Not any more!!!

Poor Dawn!!!  
I have to look at schematics (which dont give size) and or rely on Dawn to know what goes where....  
She is a blessing.......

So that is why your getting 3 different Parts numbers at Shimano for Spool bearings...
They really are diff sized bearings.....
