About
The FBB Phasing Differential is essentially two FB pancake gear sets mounted back to back with dynamic splines connected. This design provides a 1:1 through ratio from a primary drive source to secondary elements of a machine, with optional speed or position adjustment. It is specifically engineered for dynamic registration of rotating elements, making it an ideal differential for applications such as roll registration or angular shaft phasing. The FBB series features a compact, low-backlash design, which is particularly beneficial for end-of-roll mounting scenarios. These characteristics ensure precise and reliable operation in demanding industrial environments where continuous adjustment and synchronization are critical.
