COMPRESSION SPRINGS

SPEC compression springs provide design engineers, draughtsmen, production and maintenance departments with precision engineered springs in an economical and time-saving way. The Spec service saves time and therefore money, as design work and calculations are no longer required.

LOADS

Load values shown are based on a service life of 50,000 cycles at 0.50 stress range.

For normal service, springs should not be compressed below L₁. To determine the load at any working length use rate proposed deflection. P=(L-L_x) x R where L_x is the new load height. Reference only.

1 lb = 4.448 Newtons

1 Newton = 0.225 lb
