The ASA 100/2 roller chain from DONGHUA is a double-strand power transmission component, manufactured under the ASA/ANSI standard. It is used to transmit motion between parallel shafts in a wide variety of industrial equipment, from conveyors to production machinery. Its carbon steel construction with heat treatment provides wear and fatigue resistance, making it suitable for continuous service in demanding environments. MR Accesorios Industriales carries this brand as part of its power transmission line, with technical advice to select the right chain for the application.

This item is a roller chain from the ASA 100/2 series, which indicates a pitch of 31.75 mm (1 1/4 inches), a roller diameter of 19.05 mm, and an inside width of 19.05 mm. The "2" designation corresponds to double-strand, meaning two single chains assembled in parallel, which multiplies the load transmission capacity compared with a single chain. DONGHUA manufactures it according to the ASA/ANSI standard, with carbon steel plates and case-hardened pins to withstand tensile and bending stresses in continuous service.

Typical applications for an ASA 100/2 chain include main drives in belt or roller conveyors, bucket elevators, mill drives, mixers, compressors, and heavy machinery in general. It is also used in equipment where two shafts must be synchronized with a high transmission ratio and limited space. Because of its double-strand design, it is common in installations handling high loads or significant torque, provided the sprockets are compatible with the pitch and number of strands.

To install an ASA 100/2 chain, it is essential to check sprocket alignment, proper tension, and correct lubrication. Excessive tension accelerates wear on rollers and bushings, while low tension causes jumping and noise. It is recommended to use sprockets with the same pitch and number of strands, and to monitor wear by measuring chain elongation. In double-strand drives, sprockets must have aligned teeth to avoid uneven loads between the two strands.
