Why Nord-Lock washers

10 reasons that speak for Nord-Lock

Dynamische Beanspruchungen: Wechselnd, Stroßbelastung, Vibrationen, Temperatur Dynamic loads: Alternating or shock loads, vibration, temperature
Normen empfehlen oder schreiben Sicherungsmaßnahmen vor Standards recommend or prescribe locking elements
Vorspannung allein ist kein Garant für ausreichende Sicherung Preload alone is no guarantee of adequate locking function
Andere Sicherungsmethoden sind wirkungslos (z.B. Kontern, Körnen, Palmutter, etc.) Other securing methods are ineffective (e.g. double nut, thread punching, pal nut, etc.)
Erhält die Vorspannung (Konstruktionsprinzip einer Schraube) Maintains the preload (design principle of a bolt)
Verhindert das Auseinanderfallen der Komponenten Prevents the bolting components from falling apart
Konformes Sicherungselement (ETA, abZ, EBA) Conform securing element (ETA, abZ, EBA)
Reduktion von Instandhaltungsmaßnahmen /-kosten Reduction of maintenance activities and costs
Unkompliziert (flache Scheibe durch Nord-Lock austauschen) Easy to use (replace flat washer with Nord-Lock)
Lebenslange Garantie auf die Sicherungsfunktion Lifetime warranty on the securing function

Customer success stories

People Providing an antidote to disaster Philippe Nouaille is responsible for overseeing how nuclear plants could be better secured against earthquakes – the natural disaster which gives nuclear engineers their biggest headaches. Read more
Customer Cases A Wind-Win Situation Wind turbine towers are designed to flex and bend, which helps them dissipate the significant forces being exerted upon them. However, this had been causing dangerous failures in the bolts. Read more
Customer Cases Eliminating bolt loosening for good At power plants across the world, gas turbines are becoming increasingly vital to the world’s power supplies. Mitsubishi Heavy Industries currently manufacture ultra-large gas turbines, which are more than six metres tall and over 16 metres long. Read more
Customer Cases The power of the sun: transformed by Siemens turbines Assembling an industrial-sized turbine requires acres of room. It also requires thousands of bolts and washers to be assembled and tightened to guarantee a service life of the product, which in the solar energy, biomass, oil and gas sectors, is typically upwards of 30 years.
