Elastic buffering and vibration absorption capability	Ingeniously engineered, each hinge of the chain is a reservoir for lubricating oil, granting our sprocket superior buffering and vibration absorption capabilities, especially compared to rigid teeth contact.
Accurate average transmission ratio	The precise meshing between our sprocket and chain preserves an accurate average transmission ratio, effectively eliminating the risk of elastic sliding commonly seen in belt transmissions.
Structural diversity	Versatility is at the heart of our sprocket design, which can be customized into integral, spoke, or combination structures, tailored to various diameters and specific application needs.
Materials and Heat Treatment	Crafted from materials that guarantee strength and wear resistance, our sprocket teeth undergo meticulous heat treatment, achieving a commendable hardness of 40-45 to withstand rigorous operations.
Maintenance	Proper installation is key, ensuring the sprocket remains tight without swinging or tilting. Regular lubrication minimizes wear, and adequate storage protection is essential when the sprocket is not in use, safeguarding its longevity.
