Drive Chains Excel High Duty

John King’s Excel High Duty Drive Chain is an upgraded offset side bar chain designed to improve service life and operational reliability. While maintaining standard dimensions, the chain has been reinforced in critical areas, making it ideal for heavy-duty applications. Available in 4.00” pitch and above, the Excel chain has demonstrated superior performance in challenging environments where other manufacturers have failed.

Key Technical Features of Excel High Duty Drive Chain:

1️⃣ Uprated link plate material: Heat-treated for maximum strength and integrity, allowing the chain to endure higher loads and ensure long-lasting performance.

2️⃣ Optimized material and heat treatment: Maintains smooth gearing performance throughout the chain's lifespan, reducing wear and extending its service life.

3️⃣ Increased bush wall thickness: Designed to withstand higher bearing pressures, ensuring robust performance in demanding conditions.

4️⃣ Dual lubrication holes: Allows lubricant to penetrate the bearing pin surface, reducing friction and wear while enhancing overall durability.

5️⃣ High-specification bearing pin: Ensures reliable and extended operation, even under heavy-duty conditions.

6️⃣ Grease access through pin: Facilitates the introduction of lubrication into critical areas, protecting the chain from friction-related damage.

7️⃣ Anti-rotation flat design: Provides secure mechanical retention of the pin, preventing rotation and ensuring stability during operation.

Special Applications:
For ultra-high-duty applications, consider the upgraded Excel standard available in sizes larger than JK4063. This chain has proven reliability in more challenging applications, significantly extending the service life compared to competitors' offerings.
