When a drive runs under high load, the TSUBAKI RS-H series roller chain is built to handle it. The code tells you the chain type, pitch, and strand count: RS for ANSI roller chain, the number for pitch, H for heavy-duty, and the final digit for single or double strand. You'll find these chains on conveyors, mills, mixers, and other continuous-process equipment where standard chains may not hold up.

Reading the code is straightforward. RS means ANSI roller chain. The number that follows is the pitch in eighths of an inch—60, 80, 100, and 120 are common examples. The H shows it's the heavy-duty version, with thicker plates and stronger pins. After a hyphen, the last digit gives the strand count: 1 for single, 2 for double. So RS60-H-1 is a pitch-60 heavy-duty single-strand chain, and RS80-H-2 is pitch 80, heavy-duty, double-strand. Match this code to the one on your drawing or the chain you're replacing.

These chains show up in clinker conveyors, bucket elevators, hammer mills, and balanced feed mixers, as well as in cement, ceramics, and mining operations. They also drive pumps, compressors, and process equipment where the transmission faces starts under load, dust, temperature swings, or spotty lubrication. Because they're heavy-duty, they resist wear and fatigue better than a standard chain of the same size.

Selection depends on the power you need to transmit, the speed, sprocket tooth counts, center distance, and the environment. Check that the pitch matches your sprockets and that the strand count is right. During installation, align the shafts, set the tension, and lubricate for your operating regime. Good sealing and regular lubrication go a long way toward extending service life, especially where dust or moisture is present.

ANSI roller chains are made to standards that cover dimensions and strengths, so chains from different brands can be equivalent. When comparing, confirm that pitch, strand count, and plate type match the original. The TSUBAKI RS-H series is a heavy-duty reference, and alternatives with the same designation may be available. If you're unsure, send us the code stamped on the chain or the pitch and strand measurements.
