DiAcro hyd press brake shear pin


Jun 25, 2016
The 1/4 in. Dia tubular steel shear pin in the ram positioning shaft sheared, and over torque cause was corrected. But I need a new shear pin. The remains look just like a steel roll pin but those are hard, tempered steel which I seriously doubt were used as shear pins in this machine. I’m sure it’d take a huge force to shear them. So what to use as a replacement! I’m thinking of a solid brass rod flattened slightly to stay in place. Might try something I’m sure would shear at less torque than the steel,original since it is easy to replace and shearing caused no problem but time loss.
