Case Studies

Grease-Free High-Torque Hinge

A high-torque grease-free hinge.

It generates no metal particles and uses no grease or other lubricants, enabling reliable operation in a wide range of environments.

The hinge supports high torque and securely holds heavy enclosures at any desired angle.

To prevent stick-slip, STAF applies proprietary technology to the sliding surfaces, ensuring smooth and stable opening and closing performance.
