13.5mm OD Stainless/Carbon steel Compression spring up to 1000mm long
These are Cut springs!
Note: these springs are cut from continuous lengths so they do not have the conventional machine finished ends, even if I do show a finished end on my images!
We have limited stock at the moment but will be ordering more, so if you have any requirements or questions please ask.
To order lengths not listed, please order multiples adding up to the length you require - or nearest length above (i.e. 250mm = 2x100mm + 1x50mm) , the prices are per mm so there will be no extra charge doing this.Then 'contact seller' to tell me exactly what you want (i.e. one length uncut of 250mm). If no further instructions are given, all springs will be cut to the ordered lengths i.e. 2x100mm & 1x50mm.
To calculate the inside diameter, subtract 2 x the wire diameter from the outside diameter, then take off another 5% from your answer. This should give you a safe measurement.
How to calculate the Rate of a spring
The Rate given in the listings (N/mm/cm) are for a 1 cm length and are given ONLY as a guide. NOTE: The Rate is dependant on the number of active coils in the spring, so will change with the length ordered.
