Product Description

Auto Motor Sprocket Spare Parts Silent Timing Drive Engine Adjusting 420 420F3 420HF1 420HT Pitch 12.7mm Motorcycle Roller Chain
 

As a professional supplier deeply rooted in the motorcycle parts industry, Ocean Group focuses on the R&D and production of high-quality motorcycle chains.
We support the wholesale of full-range chains, covering the needs of various motorcycle types such as street bikes, off-road bikes and cruisers.
We provide in-depth customization services from specification parameters to surface treatment, and can undertake large-volume orders to accurately match your production or sales plans.
We always control quality in accordance with high industry standards, and at the same time offer highly competitive cooperation prices, allowing you to balance quality and cost.

Motorcycle chains are core drivetrain parts that transfer engine power to the rear wheel.

Exposed to tough conditions (tension, friction, dust, mud), they need regular lubrication. Poor maintenance causes wear, rust, or even breakage-hurting engine efficiency and safety.

Chains often need replacement: they're harder to replace and require more upkeep than belts. But belts are less durable and reliable-prone to cracking/slipping from heat/wear, with shorter lifespans than well-maintained chains.
Quality and credibility are at the core of our business philosophy, and Ocean are committed to providing the best services and top-notch products to our customers. For more information or samples, please reach out to us, and Ocean guarantee a prompt response.

Product Parameters

The key feature of a sealed chain is the inclusion of O-rings or X-rings, which form a barrier between the inner and outer plates of the chain. These rings serve two main purposes:
Lubrication Retention: They trap lubricant inside the chain, preventing it from escaping during use. This helps reduce friction between the chain's moving parts, ensuring smoother operation.
Contaminant Protection: The seals also protect the chain from dirt, dust, water, and other contaminants that could otherwise wear down the chain or sprockets over time.

Ring Type	Function	Benefit
O-ring	Prevents lubricant leakage.	Lower friction, longer chain life.
X-ring	Reduces friction further.	Even smoother operation, better performance.

 

Motorcycle chains come in several varieties, each designed for specific purposes. Here are the most common types:
Standard Chains: These are the most basic type of chain and do not include any seals. They require regular lubrication and are more prone to wear and rust.
O-ring Chains: These chains have rubber O-rings between the links that help retain lubrication and keep contaminants out.
X-ring Chains: Similar to O-ring chains, but the X-shaped rings provide even more protection and reduce friction more effectively.
Sealed Chains: These chains combine the benefits of O-ring and X-ring technology, offering maximum protection against contaminants and longer-lasting performance.

Chain Type	Key Features	Best For
Standard Chain	Simple, no sealing mechanism	Casual riders, budget-friendly
O-ring Chain	O-rings retain lubrication, protect from debris	Long-distance riders, street bikes
X-ring Chain	X-shaped rings for reduced friction and longer lifespan	High-performance bikes, racing
Sealed Chain	O-rings or X-rings, best protection and longevity	All types of riders, wet conditions
