The standard version of our stainless coil flat spring for industrial use, produced at established force and travel combinations. Where the standard covers the requirement, it is the faster route to delivery than a wholly custom design.
Proven configurations that cover a broad range of industrial retracting and tensioning requirements.
No new design cycle when a standard fits, which shortens the path to production.
Identical material and forming as the custom version, at established dimensions.
Measure the existing spring's strip width and thickness when ordering a replacement, and tell us the drum diameter. Those three figures identify the configuration faster than anything else.
Custom design cycles for requirements a standard configuration would meet
Obsolete coil springs in existing equipment with no remaining supply
Dimensional and load figures are set per order against your drawing or sample, so they are marked TBC rather than filled with catalogue numbers.

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
The standard and custom coil flat springs are the same part in different configurations. Start from the standard unless your requirement falls outside it.
Send us the force and the travel you need and we will say directly whether a standard covers it.
Yes. It is a reference configuration rather than a fixed catalogue item.
Yes. Send the original, including a failed one, and we will reproduce it.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
