Caution

    Product Description

    This is a standardized series so that the spring constant is constant for the same diameter.
    [Features]
    · WF type, Maximum allowable deflection 45%
    · WL type, Maximum allowable deflection 40%
    *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 WF and here for WL for the catalog of standard parts for press dies.

    Round Coil Springs, O.D. Referenced, Piano Wire, WF / WL

    Round wire compression springs standardized so that the spring constant is the same for the same outer diameter. Select WF (maximum allowable deflection 45%) or WL (40%) by the required stroke and load.

    • Material: piano wire (SWP-A).
    • Solid length is a reference value and may vary slightly by lot. Number of uses: 1,000,000 cycles.
    • Some WF sizes (marked in the dimension table) have both end faces unground.
