The NPL series provide HIGH force with flexible guide to absorb lateral movement and misalignment in dies. Ideal for stamping applications where height is restricted.

Available in forces from 7,400N (1,665lbf) to 75,000N (16,860 lbf), NPL springs provide high force in a shorter profile when compared to the NP Spring Series. Range of stroke lengths for models 750 through 3000 is 12.7 mm to 250 mm. Range of stroke lengths for models 5000 and 7500 is 25 mm to 250 mm. A variety of mounting options are available which utilize the upper C-groove, lower U-groove and bottom threaded holes.
