Falk 0704626 Grid Coupling Hub

FALK 0704626 Grid Coupling Hub is a shaft-mounted component that forms one half of Falk’s grid coupling assembly. It features a 1.375 in bore for mounting on a shaft, and the part is identified by Falk's catalog number 0704626. This hub is designed to be used with the matching grid coupling elements to connect two shafts in industrial power transmission applications, delivering a reliable interface for torque transfer while accommodating simple shaft alignment differences. The grid coupling concept relies on hubs that hold the grid plates in place and distribute load across the coupling, with fasteners and grids that pair with the hubs to complete the assembly. When planning a replacement or new installation, ensure compatibility with the corresponding Falk grid coupling system components and verify that the bore size matches the drive shaft diameter. The 1.375 in bore size indicates the intended shaft diameter range for this hub within the Falk lineup, making it suitable for standard, smaller-to-mid size power transmission setups.
