Designing & Manufacturing Precision Roller Chains for High-Performance Power Transmission
Donghua specializes in the design and manufacturing of precision roller chains-the industry standard for reliable power transmission in industrial machinery, conveyors, and drive systems. Available in A series and B series short pitch configurations, our chains excel in applications requiring high dynamic loads and extended wear life. As a leading global manufacturer since 1991, we deliver precision roller chains engineered for durability and consistent performance.
Precision Roller Chain Technology: Engineered for Durability
Donghua precision roller chains are manufactured with advanced engineering features that ensure exceptional performance:
Wide Waist Design: For 60H and larger chains, the wide waist design enhances strength for demanding applications.
Spheroidized Chain Plate Holes: Chains sizes 80 and larger undergo ball treatment after heat treatment to significantly increase fatigue strength.
Solid Bushings and Rollers: Solid bushings provide extended wear life; solid rollers interact smoothly with sprockets for reduced friction.
Hot Dip Lubrication: Chains come pre-lubricated with hot dip lubrication for improved wear life and immediate readiness.
Multiple Strand Options: Available in single and multiple strands (duplex, triplex) for higher load capacity.
