A general industrial compression spring made to your specification, covering the broad middle of the range where most machinery springs live. This is the part that gets designed when a catalogue spring is close but not close enough.
The spring is built around the force you need at the height you need it, which is the specification that actually matters in service.
Carbon steel, 65Mn, music wire and stainless, with any of nine finishing routes, chosen against the working environment.
Open, closed, closed and ground ends, chosen against how the spring seats in your assembly.
Specify the force at working height as your primary requirement and let dimensions follow. Specifying dimensions alone leaves the force as an accident of the design.
Catalogue springs that are close on dimensions and wrong on force
Machines held up waiting for a spring size that nobody stocks
Dimensional and load figures are set per order against your drawing or sample, so they are marked TBC rather than filled with catalogue numbers.

Every batch follows the same seven step route, with tensile testing and magnetic powder flaw detection carried out before packing.
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.
Against a stock spring from a distributor, a custom part matches your requirement exactly instead of approximately, at the cost of a production lead time rather than shelf availability.
That is the better starting point. Give us the force, the working height and the space available and we will design the geometry.
Yes. A broken spring still carries wire diameter, coil diameter and coil count, which is most of what is needed.
Standard production is 7-15 days after order confirmation, including surface finishing.
Send your drawing, dimensions or a sample. We will confirm the specification and come back with a price and a lead time.
