Black Series springs are made for exceptionally heavy duty applications, and can withstand higher loads than gas (nitrogen cylinder) springs, rubber or polyurethane springs, and disc springs of similar size.

These springs are exclusive to Bordignon, and are manufactured in a patented cold coiling process.

The processes, treatments and checks involved are the same as those we use for our die springs, and guarantee unquestionably superior quality and durability.

Our Black Series springs eliminate the problems typically associated with gas, disc and polyurethane springs. They are easy to use, easy to install, maintenance-free, totally safe (no more pressure vessels in the work area), unaffected by contaminants, lubricants, metal chips, and resist high working temperatures and speeds. In short, totally reliable spring action!
