High strength chains are produced to ANSI specifications and are offered in three styles. Drives® Z Series, HR series and HZ series chains lead the industry in manufacturing processes, critical to performance in demanding fatigue and wear life applications.
Z Series: Available in riveted or cottered style, our Z Series chains contain a through-hardened pin and after heat treat, ballized link plates for increased fatigue strength.
HR Series: Available in riveted or cotter style. HR Series chain contains a carburized pin, after heat treatment ballized link plate holes, and heavier sidebars for increased fatigue strength and wear life in high speed and abrasive applications.
HZ Series: Available in riveted or cottered style, Drives® HZ Series chain contains a through-hardened pin, heavy sidebars and after heat treatment ballized link plate holes for more moderate speed and high load/pulsating type applications. These chains deliver a higher working load capacity and additional resistance to fatigue in heavy load applications.
