Sealed Motorcycle Chain (O-Ring & X-Ring Chain)

KINGSCHAIN's sealed motorcycle chains are crafted using chromium-vanadium alloy steel pins for good wear resistance. We also utilize cold-forging technology to produce seamless bushings with higher roundness. Coupled with high-viscosity lubricants, our chains provide racing-level performance in terms of wear resistance, noise reduction, and heat dissipation, capable of withstanding speeds.

O-Ring Chain
Our O-Ring chain is designed to meet the tougher service life requirements for both on-road and off-road riding. Featuring O-Ring seals, it locks in the lubricants, ensuring that the bushings and pins stay lubricated at all times. As a result, the O-Ring chain outlasts non-sealed chains by a significant margin. Made from high-alloy steel, solid rollers, and advanced sealing technology, it is both lighter and more fatigue-resistant.

Features:
Easy to maintain
Exceptional high-speed performance
Long service life
Reduced need for tension adjustments
Low noise
Less sprocket wear

Applications:
The O-Ring chain is a high-performance chain specifically designed for racing motorcycles.

X-Ring Chain
The X-Ring chain utilizes "X" shaped seals, which permanently lock the lubricant inside the chain, providing even better wear resistance. Compared to traditional O-Ring chains, the X-Ring chain offers not only a longer lifespan but also quieter operation, smoother movement, and greater energy efficiency. The X-Ring chain is designed for high-power motorcycles and cargo bikes, especially for environments requiring superior waterproof, dustproof, and dirt-resistant capabilities. Its lifespan is expected to be 3-5 times longer than that of standard chains.

Features:
Solid pins made of high-quality alloy steel
Seamless bushings made of high-quality alloy steel
Smooth rollers made of high-quality alloy steel
Nice lubricant sealing performance compared to O-Ring chains

Applications
The X‑Ring chain is ideal for high-power motorcycles, touring bikes, sport bikes, and heavy-load bikes, and is especially suited for conditions demanding nice water, dust, and dirt protection.
