Additional Information
Clamping nuts are essential for securing pins with pin tabs and anti-torsion elements. They enhance machine stability, allowing it to withstand higher loads by preventing bending of bearing covers, such as those at the swiveling arm, boom, and stick. Care should be taken to avoid over-tightening, as this can lead to bent bearing covers, broken welded seams, excessive friction, increased wear, and bearing damage.
