The motorcycle chain is usually composed of inner links, outer links, pins, bushings, rollers, etc. These components are precisely matched and manufactured to ensure the strength and wear resistance of the chain. It is widely used in most motorcycles and, with its excellent strength and wear resistance, can easily meet the needs of daily riding.
Oil seal motorcycle chain, as the name suggests, is to add an oil seal design to the traditional motorcycle chain. Specifically, this chain incorporates an oil seal ring (or oil seal rubber ring) between the inner and outer chain plates, thus forming a relatively closed lubrication system. This oil seal can wrap the lubricating oil in the middle, effectively preventing the leakage of lubricating oil, and at the same time blocking the intrusion of impurities such as sand, soil, moisture and dust. The wear and failure rate of the chain is greatly reduced, thereby extending the service life of the chain. In addition, oil seal chains also have the characteristics of low noise, torque and high tensile strength.
Oil seal chains are often used in medium to large displacement motorcycles because these models require higher transmission performance and stability. 

Jiangxi Hengjiu is a professional manufacturer of motorcycle chains. Since its establishment, it has consistently focused on this field. Making a high-quality motorcycle chain with a long service life is our main area of expertise. We use high-grade alloy steel. By using professional heat treatment equipment and techniques, the physical properties of the material are further optimized to enhance the tensile strength and fatigue resistance of the chain.
Our motorcycle chains have excellent wear resistance, low initial elongation rate, smooth operation with low noise, superior product quality and stable quality output.
