*This product is handled as mechanical parts and parts for press dies, and this page conforms to the contents published in the catalog of mechanical parts. Please see here for WY and here for WR for the catalog of standard parts for press dies.
Round Coil Springs, O.D. Referenced, Piano Wire, WY / WR
Round wire compression springs standardized so that the spring constant is the same for the same outer diameter. Select WY (maximum allowable deflection 75%) or WR (60%) by the required stroke.
- Material: piano wire (SWP-A). Both ends unground.
- Solid length is a reference value and may vary slightly by lot. Number of uses: 1,000,000 cycles.

- Load calculation: load = spring constant × deflection
(SI units) N = N/mm × F mm; kgf = kgf/mm × F mm
(kgf=N×0.101972)
All WY types have unground end faces.
Service life: 1 million cycles
WR: Fmax. (allowable deflection) = L×60%

- Load calculation: load = spring constant × deflection
All WR types have unground end faces.
Solid length is a reference value. Values vary slightly between lots.
