Anti-Loose Fastener Technology For High Vibration Conditions NordLock vs SCHNORR vs LANFRANCO

Anti-Loose Fastener Technology For High Vibration Conditions NordLock vs schnorr vs LANFRANCO

In high-vibration industrial environments such as construction machinery, motor equipment and rail transit, standard fasteners are prone to loosening, preload loss and even component falling off. Traditional spring washers and nylon lock nuts are not suitable for long-term strong vibration scenarios. NordLock, schnorr and LANFRANCO are three mainstream imported anti-loose solutions with different principles and application focuses.

1. NordLock Wedge Locking Washers

NordLock anti-loose system adopts double-sided wedge tooth structure. When the nut is tightened, the wedge surface generates locking force. When the bolt is subjected to vibration, the wedge opening force counteracts the rotation tendency, achieving the "tighter under vibration" effect.

2. schnorr Safety Washers

schnorr safety washers are made of high-strength spring steel with precision ratchet teeth. Elastic preload and mechanical tooth engagement work together to prevent nut rotation under vibration impact.

3. LANFRANCO All-Metal Self-Locking Nuts

LANFRANCO nuts rely on the elastic deformation of the nut body to lock the thread without nylon insert. It can withstand high temperatures above 300℃ and strong vibration without aging failure.

4. Application Comparison

NordLock is suitable for large bolts in wind towers and heavy machinery. schnorr is ideal for compact motor and reducer equipment. LANFRANCO is recommended for rail transit and high-temperature industrial equipment.
