OverviewThe ZF Duoplan two-speed manual gearbox is designed for machine tool main-spindle drives, test benches and other high-torque applications. Variable installation positions allow use in turning machines (horizontal B3/B5) and machining centres (vertical V1/V3). The gearbox supports direct spindle mounting (Inline & TSC) for flexible integration.
Key Facts- Easy assembly: compatible with major motor manufacturers and versions
- Wide application range: universal and flexible design
- Versatility: direct mounting to spindle (Inline & TSC) for multiple use cases
