#50 is 500 series, im guessing #60 is what you need to look for....

yes #60 will work great!

There is a difference in #60 and 630.630 is wider than standard #60. Same is true for #50 and 530. You can use 630 chain on a 60 sprocket but not the other way around.

To answer the question tho a 630 is a wider than standard 60.

I bought some generic 50 series chain when i did mockup, it fit the sprockets... the deviation is 520/525/530, you cant use 530 sprockets with 520 chain, is that what your saying?

I read something somewhere about the chain sizes.

It was like the first number is the pin center distance.
#20 is 2 1/8's so pin center is .25"
#30 is 3 1/8's so pin center is .375"
#40 is 4 1/8's so pin center is .5"
#50 is 5 1/8's so pin center is .625"
#60 is 6 1/8's so pin center is .75"
and so on.

I think the second number follows a similar rule pertaining to the width between plates, but I can't remember it.
And there is something the third stands for too, but I can't remember it either.  I'm sure a search would explain it, or somebody else can chime in...

i think 2nd and 3rd is width...

Title: Re: Sprockets
Post by: Doug Heim on February 17, 2009, 09:03:26 PM

the 3rd I thought was for double and tripple row, Hmm maybe not.

Title: Re: Sprockets

2nd and 3rd are width reference. A(dash) -2 would be a duplex and a -3 would be a triplex and so forth.

Found this.


 Chain Size Chart
Chain Size    Pitch    Inner Width - roller
415    1/2    3/16
420    1/2    1/4
520    5/8    1/4
525    5/8    5/16
530    5/8    3/8
630    3/4    3/8

Damn, you guys were all over that!  Yes I found it.  second and third number are width between plates and are measured in 1/8's also. 

So 525 would read...
5/8ths pitch
2.5/8ths width between plates.

And Fabr is right a dash and then a number designates number of strands.

So now I am wondering how you determine sprocket width.  if you have a 520 chain then the width between plates is 2/8's or .25".  so do you want a .25" wide sprocket?  that just seems kinda cutting it close to me, but I could be wrong...

Usually there is a little jiggle between it. You need to round the sides of the teeth slightly too. I'm sure the chain is slightly over 1/4 so a 1/4 inch wide sprocket should work.
