About
The SHD-2SH Hollow Shaft Gear units are designed for applications requiring an extremely flat profile and high positioning accuracy. These units incorporate a large hollow input shaft and a robust cross roller bearing, which enables direct mounting of loads to the unit, eliminating the need for additional support bearings. Key features include zero backlash, a hollow through bore, high stiffness from the cross roller bearing output, and high radial, axial, and moment load capacity. This design makes them suitable for demanding applications where space and precision are critical. The SHD-2SH series offers various sizes and ratios, providing flexibility for different torque and stiffness requirements.
