DONGHUA Power transmission

ANSI roller chains are an essential component in mechanical power transmission. They are used to transmit motion between parallel shafts by means of sprockets, offering a robust and efficient solution for a wide variety of industrial applications. At MR Accesorios Industriales we supply the DONGHUA brand, recognized for its quality and reliability in the market. If you need advice to select the right chain, our technical team is available to help you request a quote for the option that best suits your requirement.

The designation of ANSI chains follows the ANSI standard and is made up of numbers that indicate the pitch and load capacity. For example, the ASA 35 series corresponds to a pitch of 9.52 mm, with rollers 5.08 mm in diameter and an inner width of 4.78 mm. The suffixes /2 and /3 indicate double and triple strand configurations respectively, which multiply the transmission capacity. Thus, ASA 35/2 is double strand and ASA 35/3 is triple strand. Other examples such as ASA 40, ASA 41 and ASA 50 follow the same logic, with larger pitches that allow higher loads.

These chains are used in a wide range of industries in Argentina, such as food, metallurgical, agricultural and mining. They are found in conveyors, machine tools, bottling equipment, conveyor belts and transmission systems in general. Their versatility and strength make them suitable for demanding environments, provided that the pitch and number of strands are selected appropriately for the required load and speed.

To correctly select an ANSI chain, it is essential to consider the power to be transmitted, the rotation speed, the type of load and the environmental conditions. Sealing and lubrication are critical: in dusty or humid environments, adequate lubrication is recommended and wear should be checked periodically. Sprocket alignment and correct chain tension extend its service life. In multi-strand assemblies, ensuring sprocket synchronization is essential to avoid uneven loads.

Regarding equivalences and interchangeability, ANSI/ASA chains can be interchanged between different manufacturers that comply with the same standard, as long as the standardized dimensions are respected. It is important to verify the pitch, roller diameter and inner width to ensure compatibility with existing sprockets. The DONGHUA brand offers products that comply with these standards, making replacement easier in equipment that originally used other brands.

ANSI H series roller chains are power transmission components used to link shafts and transmit rotary motion at a constant speed ratio. Their pitch and roller design allows precise meshing with standard sprockets, making them suitable for a wide range of industrial applications. At MR Accesorios Industriales we carry the DONGHUA brand, with sizes ranging from small pitches to larger pitches, always under the ASA/ANSI standard.

The designation of these chains follows ASA nomenclature: the number appearing after the letters ASA indicates the size and series. For example, ASA 50/H corresponds to a pitch of 15.87 mm, a roller diameter of 10.16 mm and an inner width of 9.53 mm. The final letter H indicates that it is the heavy series, with thicker plates than the standard series. Other available codes are ASA 60/H, ASA 80/H, ASA 100/H and ASA 415/H, each with its standardized dimensions. Knowing these values is key to selecting the right chain.

These chains are used in a wide variety of industries in Argentina. You will find them in packaging lines, food conveyors, machines for the plastics industry, material handling equipment, transmission systems in mills and processing plants. They are also common in the agricultural sector, in seeders and harvesters, and in the metalworking industry for driving mechanisms. Their robust construction makes them suitable for environments with dust, humidity or moderate loads, provided periodic maintenance is carried out.

To choose correctly, take into account the pitch, roller diameter and inner width, which must match those of the sprocket. The heavy series (H) offers greater tensile and fatigue strength, so it is recommended when there are shock loads or when longer service life is sought. During installation, check shaft alignment and proper tension: a chain that is too tight accelerates wear on rollers and sprockets, while low tension can cause jumping. Regular lubrication with specific oil or grease reduces friction and prevents corrosion.

As for equivalences, ASA/ANSI chains are interchangeable between different manufacturers that follow the same standard, as long as pitch, roller diameter and inner width match. This makes replacement easier without having to change the sprockets. If you need a chain for a special application, such as high temperature or a corrosive environment, ask us: we can advise you on available materials and treatments. Remember that the full designation includes the standard and the series, so do not omit that data when looking for a replacement.

To request a quote for your chain, send us the full code (for example, ASA 60/H) or the pitch, roller and inner width measurements. At MR Accesorios Industriales we advise you so you can find the DONGHUA chain that best suits your equipment. Write to us on WhatsApp and we will reply shortly.
