Double-Plus Chain: The Ultimate Solution for Heavy-Duty Applications
Double-plus chains are heavy-duty transmission chains widely used in several industrial applications, including conveyors, bucket elevators, and various types of machinery. These chains are made of high-quality materials such as carbon steel, stainless steel, or alloy steel, which provide exceptional strength, durability, and wear-resistance, making it a perfect solution for heavy-duty applications.
The double-plus chain is a type of roller chain with extra-large diameter rollers that provide a greater contact surface with the sprocket. This feature reduces the pressure on the chain, sprocket, and bearings, providing better load distribution, lower wear, and longer service life. Additionally, these chains have solid bushings that provide greater strength and fatigue resistance, ensuring maximum performance and reliability.
Advantages of Double-Plus Chain
- High strength and durability
- Excellent wear-resistance
- Greater load distribution
- Reduced pressure on chain, sprocket, and bearings
- Better fatigue resistance
- Longer service life
Installation, Maintenance, and Repair
Double-plus chains require proper installation and regular maintenance to ensure maximum performance and longevity. The chain should be installed according to the manufacturer's instructions, including the correct tension, lubrication, and alignment. Regular maintenance should include cleaning, lubrication, and inspection of the chain and sprocket for wear, damage, or misalignment. If any issues are detected, the chain should be repaired or replaced promptly to prevent further damage or safety hazards.
