Produced to ANSI specification, Drives® Heavy Series chains are offered in two main styles: HR Series and HZ Series. Both lead the industry in manufacturing processes and are critical to performance in demanding markets. This being said, it is important to know how they differ so you can choose the correct series for your application.
- HR Series: Contains a case-hardened pin and heavy link plates for increased fatigue strength and wear life in high speed or abrasive applications.
- HZ Series: Contains a through-hardened pin and heavy link plates for high load or pulsating applications.
We also offer a Z Series chain with through-hardened pins and standard link plates for select applications.
