Product Information

Optical shafts are cylindrical linear motion guiding components, serving as core basic components for achieving linear motion in mechanical transmission.  Key information is as follows:

1. Basic Features

- Material: Primarily bearing steel (such as SUJ2) (high hardness, strong wear resistance), but also stainless steel (rust-proof), aluminum alloy (lightweight), etc.

- Structure: Surface is ground/chrome-plated, with precision levels including standard grade (f8), precision grade (h6), and ultra-precision grade (h5).

- Specifications: Available in diameters from φ3 to φ100mm, with customizable lengths (commonly 1 meter, 2 meters).

2. Core Applications

They need to be used in conjunction with linear bearings, sliders, shaft supports, etc., to form a linear motion system, achieving low-friction linear reciprocating motion of components, such as:

- Guide rails for automated equipment;

- Movement of the print head in 3D printers;

- Sliding of machine tool worktables.

3. Common Types

1. Chrome-plated optical shaft: Features: Chrome-plated surface for rust prevention, high hardness. Applicable scenarios: General industrial equipment.

2. Stainless steel optical shaft: Features: Strong corrosion resistance. Applicable scenarios: Food/medical equipment.

3. Hollow optical shaft: Features: Lightweight, allows for internal wiring. Applicable scenarios: Equipment with limited space.

4. Keyed optical shaft: Features: Can transmit torque. Applicable scenarios: Linear structures requiring synchronous rotation.
