Linear optical axis is a kind of product with sliding bearing guiding function and linear movement. The requirements of these linear motion systems are: simple design, best performance, low maintenance cost, use of highly selected and durable materials, high frequency heat treatment, accurate external dimensions, roundness, straightness and surface treatment.

　　1. 普通線性光軸(sf):由于普通線性光軸與線性支承點之間的接觸，普通線性光軸表面硬度很高，因此材料和熱處理方法非常重要。硬度:hrc602硬化層深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直線度:70m/1000mm軸向外徑公差g6

　　1. Ordinary linear optical axis (SF): due to the contact between ordinary linear optical axis and linear support point, the surface hardness of ordinary linear optical axis is very high, so the material and heat treatment method are very important. Hardness: hrc602 hardening layer depth: 0.8-3mm surface roughness: ra0.10-ra0.35m straightness: 70m / 1000mm axial outer diameter tolerance G6

　　2. 鍍鉻線性光軸(SFC):在普通線性光軸的基礎上，鍍鉻線性光軸鍍上一層硬鉻。它可以用在容易生銹的環境中，也可以用在不好的環境中。材料:suj2(等效)gb gcr15。硬度:hrc602硬化層深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直線度:70m/ 1000mm以下鍍鉻層厚度:3m-5m軸外徑公差g6

　　2. Chrome plated linear optical axis (SFC): on the basis of ordinary linear optical axis, chrome plated linear optical axis is coated with a layer of hard chromium. It can be used in environments that are prone to rust or in bad environments. Material: SUJ2 (equivalent) GB GCr15. Hardness: hrc602 hardening layer depth: 0.8-3mm surface roughness: ra0.10-ra0.35m straightness: 70m / less than 1000mm chromium plating layer thickness: 3m-5m shaft outer diameter tolerance G6

　　3.鍍鉻直線軟軸(RSFC):鍍鉻直線軟軸由于鍍鉻層較厚，可直接用于精密活塞桿和一些自潤滑軸承。由于其硬度適中，在許多領域得到了應用。材質:45#或40cr或2cr13硬度:hb220-260硬化層深度:0.8-3mm直線度:0.15mm/以下1000mm鍍鉻層厚度:0.02-0.05mm

　　3. Chrome plated linear flexible shaft (rsfc): due to the thick chrome plated layer, it can be directly used for precision piston rod and some self-lubricating bearings. Because of its moderate hardness, it has been applied in many fields. Material: 45 × or 40Cr or 2Cr13 hardness: hb220-260 hardening layer depth: 0.8-3mm straightness: 0.15mm/1000mm below chromium plating layer thickness: 0.02-0.05mm

　　4. 不銹鋼直管閥芯:不銹鋼直管閥芯具有高耐腐蝕性、高強度和高耐磨性，以保持其性能。適用于水、化工、蒸汽、海水等易發生氧化的場合。材質:sus404c, sus304硬度:hrc602硬化深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直線度:70m/ 1000mm以下鍍鉻厚度:3m-5m。軸外徑公差g6

　　4. Stainless steel straight pipe valve core: stainless steel straight pipe valve core has high corrosion resistance, high strength and high wear resistance to maintain its high efficiency. It is suitable for water, chemical industry, steam, sea water and other occasions prone to oxidation. Material: sus404c, SUS304 hardness: hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10-ra0.35m straightness: 70m / 1000mm chrome plating thickness: 3m-5m. Tolerance of shaft outer diameter G6

　　鍍鉻空心軸:由于空心結構，空心軸大大減輕了重量，簡化了結構。它的內部適合于刺穿測量線，壓縮空氣，添加潤滑油，或用于機械臂。公司還承接各種非標直線光軸(包括直徑、公差、材質等)的定制及各種軸類加工。

　　Chrome plated hollow shaft: because of the hollow structure, the hollow shaft greatly reduces the weight and simplifies the structure. Its interior is suitable for piercing measuring lines, compressing air, adding lubricating oil, or for mechanical arms. The company also undertakes all kinds of non-standard linear optical axis (including diameter, tolerance, material, etc.) customization and all kinds of axis processing.
