TSUBAKI RF-US roller chains are built for power transmission in heavy-duty service, connecting toothed sprockets to move force and motion through demanding equipment. The design targets fatigue and wear resistance, which suits plants where uptime and simple maintenance matter. MR Industrial Accessories supplies this line to customers in the United States and several Latin American countries, and can help you match the right pitch and configuration to your drive.

Reading the code is straightforward. RF marks the TSUBAKI roller chain line. The digits after it give the pitch in eighths of an inch: RF100 is a 1 1/4" pitch, RF120 is 1 1/2", RF140 is 1 3/4" and RF160 is 2". The -US suffix identifies the heavy-duty version, and the final digit tells you the strand count, so -1 means single strand. For example, RF100-US-1 is a single-strand heavy-duty chain with a 1 1/4" pitch.

These chains appear in food processing, cement, mining, steel and material handling operations. Typical drives include drag conveyors, bucket elevators, mill drives, kilns and continuous process lines. Dust, elevated temperatures and fluctuating loads are common in these settings, and the chain's resistance to wear and fatigue supports reliable operation with less frequent maintenance attention.

When selecting an RF-US chain, review the power to be transmitted, the speed, the sprocket tooth counts and the center distance. Shaft alignment and tension deserve close attention: an over-tightened chain speeds up wear on rollers and bushings, while a loose one risks jumping teeth. Lubrication method matters too, whether manual, drip or bath, depending on speed. Inspect sprockets as well and replace any with hooked teeth.

TSUBAKI RF-US series chains interchange with other brands built to the ANSI standard for heavy-duty roller chain when pitch, strand count and roller dimensions align. For a quote, provide the complete part number, such as RF120-US-1, plus operating details if available. MR Industrial Accessories can point you to the equivalent for the chain you are replacing.

Frequently asked questions

What does the -US suffix indicate on a TSUBAKI RF chain?
It marks the heavy-duty line, intended for more severe loads and conditions than a standard chain, with greater resistance to fatigue and wear.
How do I pick the correct pitch?
Pitch depends on power, speed and the space available. A larger pitch carries more load but allows lower speed. Share your equipment data and we will help you choose.
What lubrication should I use?
That depends on speed and environment. Low speeds may allow manual or drip lubrication; higher speeds usually call for bath or circulation. Correct lubrication limits wear and extends chain life.
