The NZ Series features our exclusive SDH Pin Treatment for superior strength and long life. In addition, all NZ Series chains have solid bushings and quad-riveted pins.

Features:

• Solid Bush - Cold-Formed High-Precision Bushing: Solid bushing chains have high wear resistance. The cold-formed solid bushings have a smooth seamless surface with complete roundness.
• SDH Pin - Extreme Impact Pin Strength: SDH pin treatment creates an extremely hard Chromium Carbide Layer on the pin's surface. But at the same time, the inner core is maintained soft to absorb shock loads of extreme jumps, etc.
