Where to buy a small strong spring?
Hi,
Hopefully someone will be able to help. I’m needing just two 14mm diameter by 50mm long springs which each have a rating of around 8kg per inch
travel. Hmmm
Where on earth would I get that? Any ideas?
Thanks in advance

RS do some but no idea what 4N/mm is compared to 8ld/inch
edit, just read again and you say 8kg/inch not 8lb/inch in that case if google right, 8kg/in = 17.6lb/inch = 3.08 N/mm so the RS @£8 for 10 @ 4N/mm =
22lb/in = 10kg/inch??
but you better check if the RS ones do the job and my maths, God i feel as if ive finally done something productive in my lunch time for once.
eithe special order or what about motorbike valve springs? but sxpect they will be stronger than 8ld/inch
RS Stock No. 121-220

Will,
gsxr1100 valve springs are 40mm long and require 20kg force to compress by 4.4mm
So that is a rate of 5kg/mm (50N/mm). A bit stiffer than is desired.
Nice link to that springs site pity the minimum order is £15.
