Busa chain. Where & how much ??

[Cylon]

Ok, sorry but i have spent the last 13 years of my sad little life selling chain and may use this one day to hang myself

520 chains

5= 50 over 80 (80= 1") 50 divide 80 = 0.625" 5/8 pitch chain

20= 20 over 80 (80= 1") 20 divide 80 = 0.250" 1/4 internal width (roller)

530 chains

5 same as above 5/8 pitch

30= 30 over 80 (80= 1") 30 divide 80 = 0.375" 3/8 internal width (roller)

these chains come in differant grades

O-Ring can cause friction between the plates

X-Ring this seals better and less friction

Standard none of the above

Differant colours etc this is cosmetic

Hope this helps
