With its newly developed X3 roller chain series, Donghua aims to reduce wear, fatigue and maintenance requirements in industrial power transmission systems. According to the company, the X3 series offers up to three times the performance of conventional roller chains.

The X3 roller chain developed by Donghua is designed for industrial applications that require high strength, precision and long service life. Improvements to the chain’s design focus on increasing wear resistance, reducing friction and maintaining operating stability under variable load conditions.

Technical Features That Increase Strength

The optimised link plate geometry used in the X3 series aims to increase the chain’s mechanical strength and fatigue resistance. Pin and bush holes calibrated to tight tolerances reduce clearances between components and improve load distribution.

Pins with a high interference fit limit unwanted movement between chain components, while special heat treatment and pin coating help reduce wear and friction.

The chains are supplied pre-lubricated and pre-stretched. These features aim to reduce wear during the initial running-in period and make it easier to put the chain into service after installation.

Suitable for Demanding Industrial Conditions

The Donghua X3 series was developed for use in timber processing, mining, quarrying, waste management and recycling plants. Shock loads, abrasive environments, contamination and frequent stop-start cycles in these applications make chain durability critical.

Available in simplex and duplex versions, the X3 series offers a solution for power transmission applications where reducing unplanned downtime and maintenance interventions is particularly important.
