520 ZRP - Drive Chain - 120 Links

Z-ring chains feature the patented Z44 sealing rings, which greatly improve performance and wear life, making previous X-ring and Z-ring chains obsolete. 50% reduction in friction compared to traditional o-rings. Constant lubrication from special high-temperature grease in the critical pin/bushing area provides long life. High-carbon alloy pins to minimize wear and increased roller thickness to prolong durability. Thicker outer plates and quad-riveting for greater tensile strength. Rivet type link included.
