The drygear® Apiro® heavy-duty gearbox is built for applications that need more strength, more stability, and more precise fastening than the standard Apiro platform. Its die-cast zinc housing adds rigidity while keeping the system modular, making it a strong fit for equipment builders looking for a more durable gearbox solution in automation and adjustment applications.
Compared to the standard Apiro, this heavy-duty version delivers 400% greater axial force absorption, helping it handle higher mechanical loads with more confidence. It also stays grease-free and maintenance-free, which supports cleaner operation and helps reduce long-term service work and replacement costs.
With stroke options from 50 to 250 mm, a max dynamic load of 300 N, nominal torque of 2.05 Nm, 2 mm spindle pitch, and 0.5 mm per revolution feed, this version is well suited for applications that need controlled linear adjustment, repeatable movement, and a more robust gearbox design. For lighter-duty or more standard modular layouts, other Apiro® gearbox system options remain a natural comparison.
