[Cleaned & Packaged] Round Wire Coil Spring - O.D. Referenced, Stainless Steel, UY/UR/UF

Volume Discount

Three types of cleaning methods are available: degreasing, precision cleaning, and electrolytic polishing + precision cleaning. They can be ordered from one piece with the standard part number.
This eliminates the need for customer cleaning or outsourced cleaning, reducing the amount of time and effort required.

[ ! ] Both ends of * marked UF Type springs are not ground.
[!] Usage Count: 1 million times

kgf (load) = N⋅mm (spring constant) × 0.101972 × F (Deflection)
[kgf]=N × 0.101972

● How to calculate the number of coils (reference value):
Total coils = solid length / wire diameter (d) - 1
Number of active coils = total coils - 2
* The values of the number of coils are for reference only. There may be some variations depending on the lot.

[!] The values of solid length are for reference only. There may be some variations depending on the lot.
Using it compressed to the solid length may cause deformation or break after a few uses.
Be sure to use the springs within the range of the allowable deflection F max.(mm).

■Spring Constant (N/mm) [kgf/mm]
[ ! ] D12 is applicable to UY, UR, and UF Types only.
