Further to our inquiry and agreement, I am sending a drawing of the washer for which we require a price quote.
This concerns a washer compliant with the NF E 25-104 standard (French standard for dynamic disc springs; equivalent to DIN 2093 / NF EN 16983) with an outer diameter of 80.4 mm and a 41 mm bore.
It does not matter if you have a version with a smaller bore, as we need to machine the hole to a diameter of 49 mm anyway.
The annual volume is 3,000 units, with staggered deliveries of 500 pieces.
