Continuous Length Compression & Extension Springs

Engineers, designers, specifiers, repair and maintenance personnel find continuous length compression and extension springs extremely convenient for prototyping and maintenance use. These springs are designed to be cut to the desired length, as required by any application.

Compression Springs

Material: either hard drawn or music wire will be supplied, based on availability at time of shipment.

Rate: To calculate rate at desired cut length: original rate X original length ÷ new length.

Extension Springs

Material: as indicated in the tables

Rate: to determine the rate per inch of extension at the final cut length, use the following formula:

N = Number of coils per inch x length in inches

Rate = C/N, C being the constant for each size of spring, as per the tables.

Load: to determine load at an extended length, multiply the deflection by the rate obtained as per above.

Spring Looping Tool

Loops springs from 1/8” (3.175mm to ½” (12.7mm) O.D.

Used to make cross over loops on continuous length extension springs up to ½” (12.7mm) outside diameter and up to .062” (1.57mm) diameter wire. In addition, two forming punches are provided with the tool.
