V Belts?

[johnakay]

from center to center it is 10" to 12", pully's are 3".
am I right in thinking 2x3=6 + 20= 26" v belt?
or is there a different way of working it out.
I've made my own pedestal polisher same as the picture below.

Run your tape measure round them.

If the pulleys are 3" you want to use 1/2 the circumference of each pulley, which will add up to the circumference of one pulley.
Pi x D =9.4" then add on 2 x center distance.

Is there a branch of Eriks near you?

Or you can buy online, Bearing Boys have loads of types/lengths listed, and a handy calculator.

make sure you check your section, small belts are normaly A sections, tho they could be Bs, Z, or Vs

I use the old Zeus book to check me sections and normally by pulleys to suit per app.... Our local bearing boys are second to none, they've have even opened Sundays and evenings for me when iv been in the Shiite, worth trying your local place....

Which bearing supplier do you you Snowy - the one in Wickford?

 

[johnakay]

pully are 'A' sections.

If the centre distance is 10" you'd be looking at something like an SPA 750.

If the distance is 12" then around an SPA 850.

They are probably fan belt sort of sizes ?
