OTC Daihen 5th Axis Reducer L10725H00 (For B4 Series)

L10725H00 is a genuine 5th axis reducer imported from Japan by OTC Daihen, specifically designed for the 5th axis of older robot models such as AIIB4, AIIB4L, FDB4, and FDB4L. This reducer is supplied as a complete assembly containing 6 components (as shown in the figure), in its original packaging, and cannot be sold separately. Featuring a high-precision RV gear design, it ensures the repeat positioning accuracy and long-term stable operation of the 5th axis.

L10725H00 is applicable to the 5th axis of OTC older robots like AIIB4, AIIB4L, FDB4, FDB4L, etc. The reducer is shipped as a complete set from the factory, and internal parts are not sold individually. If a single internal accessory is damaged, it is strongly recommended to replace the entire set to ensure transmission precision and reliability, thereby avoiding performance degradation and multiple subsequent maintenance costs caused by mixing old and new parts.
