Hat Type FHT-Ⅰ
Product Overview
Miniature Hat Type Standard Unit: FHT Series
The FHT Series is a Miniature hat-type standard Unit designed for applications that demand compact size, smooth operation, and easy integration.
It features a large-diameter hollow shaft, allowing for convenient cable routing, piping, or installation of additional components through the center of the unit. This design not only improves system flexibility but also simplifies assembly and maintenance in complex mechanical layouts.
The FHT unit’s robust yet lightweight structure ensures high rotational accuracy and stable performance, even under continuous or high-speed operation. Its compact profile makes it ideal for use in robotic joints, semiconductor production equipment, precision instruments, and automated systems where space efficiency and operational reliability are crucial.
By combining ease of operation, excellent concentricity, and a versatile hollow-shaft design, the FHT Series provides engineers with a dependable solution for precision motion systems.
