The PDFT Series represents our heavy-duty internal return flange double nut solution, designed for large-scale industrial machinery where maximum rigidity and precision are required under extreme loads. The double nut preloaded architecture effectively eliminates axial play for consistent accuracy.

With shaft diameters ranging from 20 mm to 80 mm, the PDFT series is engineered for maximum durability. It boasts massive load capacities, with dynamic ratings up to 14,429 Kgf and peak static capacities of 89,100 Kgf. Featuring a rigidity of up to 263 Kg/µm, it is the ideal choice for heavy-duty CNC milling and industrial automation.
