Self-contained guided rod cylinder designed for piercing applications

Coldwater Machine Co. has designed guided rod cylinders for use in its fabrication equipment for punching, piercing, and notching.

These hydraulic cylinders feature an internally self-lubricated, guided rod within the cylinder body. According to the company, this provides improved reliability and less maintenance. Additionally, since there are no external guides, the new cylinder design requires a third less space than alternatives.

The guided pierce cylinders feature a steel body and provide stable, nonrotating performance with the ability to reach hydraulic pressure of up to 3,000 PSI. The company uses these cylinders in systems for appliance manufacturing, including dishwasher panel and washer cabinet lines, as well as in automotive frame and body piercing lines.
