U.S. Tsubaki RS25 bushed chain is the smallest ANSI roller chain. It is ideal for power transmission in business machines, electro-optical equipment, and precision and general industrial machines where relatively large space is allowed for miniature drives.
These chains can accommodate a large allowable load and are widely used for driving motorcycle cam shafts and power transmission machinery in general.
