Introduction
MecVel S.r.l. introduces a new safety nut designed for high performance in safety and resistance, suitable for linear actuators and screw jacks. This device ensures load safety even under maximum wear or sudden failure of the main nut.

Specifications and Operating Principle
The safety nut is constructed from steel and is positioned between the main nut and the push rod. It activates when the main nut is completely worn or collapses, maintaining the load safely. The system increases noise when the safety nut engages, providing feedback to the operator.

Advantages

• The safety nut is screwed into the push rod, preventing slippage and ensuring protection.
• Its internal thread has a different pitch than the main screw, allowing it to grip the main screw and lock the system in case of main nut failure.
• It functions in both push and pull directions, suitable for hanging loads and loads in compression or traction.

Compatibility and Limitations
The safety nut is not compatible with ball screws (VRS) but can be used with other linear actuators or screw jacks, regardless of size or screw pitch.

Conclusion
To enhance system protection, the safety nut can be requested as option “G” when configuring a linear actuator or screw jack. MecVel reserves the right to modify product information without notice.
