1. Ordinary Linear Optical Shaft (SF):

The SF variant is particularly hard due to its face-to-face contact with linear bearings. The material and heat treatment methods are crucial. It’s made of SUJ2, equivalent to the national standard GCR15, and the hardness is HRC60±2.

2. Chrome-plated Linear Optical Shaft (SFC):

The SFC model has a hard chrome layer making it more suitable for use in rust-prone or unfavorable environments. It’s widely used in industrial robots, automatic slip system devices, and more. The hardness, material, and other properties remain the same as the SF variant.

3. Chrome-plated Linear Soft Shaft (RSFC):

The RSFC is specifically designed for precision piston rods and some self-lubricating bearings. Its medium hardness allows it to be used in many areas. The material can be 45# or 40Cr or 2Cr13, with hardness HB220-260.

4. Stainless Steel Linear Shaft:

This model features high corrosion resistance, strength, and wear resistance to maintain its efficient performance. The materials include SUS404C, SUS304, with hardness HRC60±2.

5. Chrome-plated Hollow Shaft:

The hollow shaft, due to its hollow structure, significantly reduces weight and simplifies the structure. It’s ideal for threading measurement wires, compressed air, adding lubricating oil, or used in robot arms.

Material and Application

The diverse range of materials including GCR15, 45#, 40Cr, 2Cr13, SUS404C, SUS304 allow the optical shafts to cater to a broad array of industry requirements.

These optical shafts find applications in industrial robots, various electronic devices/guide rods, transmission shafts, pillars, electronics, packaging, chemical medicine, textiles, printing, engineering, transportation, steel, mines, hydraulic cylinders, gas cylinders, operating rods, adjusting rods, linear motion, automation devices, light industry, heavy industry, hydraulic and pneumatic, printing and packaging, textile and dyeing, die-casting machines, injection molding machines, slip devices and other mechanical industries.
