The ASA 50/3 chain is a roller chain with a 15.87 mm (5/8") pitch, a 10.16 mm diameter roller, and a 9.53 mm inner width. It is used in power transmissions where medium loads need to be driven at moderate speeds, with a good balance between strength and weight. It is a three-strand chain, which allows it to handle more load than a single- or double-strand chain of the same pitch. DONGHUA is an official brand that MR carries, with technical support to select the length and compatible sprockets.
This ASA 50/3 chain from DONGHUA has a 15.87 mm pitch, a 10.16 mm roller diameter, and a 9.53 mm inner width. The 50/3 designation indicates that it is a three-strand chain: three strands of rollers joined by pins, which multiplies the pulling capacity compared with a single-strand chain of the same pitch. It is manufactured under the ASA/ANSI standard, so its dimensions are interchangeable with those of other brands that follow the same standard. It is a steel chain, intended for power transmission in machinery.
Typical applications for an ASA 50/3 chain include main drives of machine tools, belt or roller conveyors, pump and compressor drives, and lifting equipment where more than one strand is required to distribute the load. It is also used in the food, wood, and ceramics industries, provided the environment is not excessively corrosive or abrasive. In general, it appears in equipment where space is limited and more torque needs to be transmitted without increasing the pitch.
To install a three-strand chain, check that the sprockets are also triple-strand and that they are aligned with each other. Lubrication is key: use the lubricant recommended for roller chains and check elongation periodically. When selecting, take into account the power to be transmitted, the shaft speed, and the number of sprocket teeth. If the chain operates in a dusty or humid environment, consider a chain with anti-corrosion treatment or an automatic lubrication system.
If you need a nearby size, such as a chain with a 12.7 mm pitch (ASA 40) or a 19.05 mm pitch (ASA 60), or if you are looking for a double-strand chain (ASA 50/2), we can help you find the equivalent. We can also quote the chain in a specific length or with a pin link. To do so, send us the code ASA 50/3 or the pitch and number of strands you need, and we will send you the options.
To order this chain or ask about an equivalent, message us on WhatsApp at MR Accesorios Industriales with the code DONGHUA-ASA-50-3 or the designation ASA 50/3. We will reply with the technical information and the corresponding quote. If you have questions about compatibility with your sprockets, also send us the sprocket data and the center distance.

Frequently Asked Questions
- What does ASA 50/3 mean?
- ASA 50/3 is a roller chain with a 15.87 mm (5/8") pitch and three strands. The number 50 corresponds to the pitch under the ASA/ANSI standard, and the /3 indicates that it has three strands of rollers in parallel.
- Is it compatible with sprockets from other brands?
- Yes, because it is a chain under the ASA/ANSI standard, its pitch, roller, and inner width dimensions are interchangeable with those of other brands that follow the same standard. It is still advisable to check the sprocket before installing.
- What lubrication does it need?
- A lubricant specifically for roller chains is recommended, applied regularly. The frequency depends on speed, load, and environment. In severe conditions, an automatic lubrication system may be necessary.
