About
The SHD-2UH Lightweight Gear Unit is designed for applications requiring high precision and a compact form factor. These gear units are axially compact and feature a large hollow input shaft, which simplifies integration and allows for direct mounting of loads. A robust cross roller bearing eliminates the need for additional support bearings, contributing to the unit’s overall efficiency and space-saving design. Key features include zero backlash, an ultra-flat design that is 15% shorter than the SHF Series, and a large hollow input shaft. They offer high accuracy, typically less than 1 arc-minute for most sizes, and a rigid cross roller output bearing. The lightweight construction results in a 30% lower weight compared to the Standard SHF Series, making them ideal for weight-sensitive applications in the space industry.
