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. 普通线性光轴(sf):由于普通线性光轴与线性支承点之间的接触，普通线性光轴表面硬度很高，因此材料和热处理方法非常重要。硬度:hrc602硬化层深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直线度:70m/1000mm轴向外径公差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. 镀铬线性光轴(SFC):在普通线性光轴的基础上，镀铬线性光轴镀上一层硬铬。它可以用在容易生锈的环境中，也可以用在不好的环境中。材料:suj2(等效)gb gcr15。硬度:hrc602硬化层深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直线度:70m/ 1000mm以下镀铬层厚度:3m-5m轴外径公差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.镀铬直线软轴(RSFC):镀铬直线软轴由于镀铬层较厚，可直接用于精密活塞杆和一些自润滑轴承。由于其硬度适中，在许多领域得到了应用。材质:45#或40cr或2cr13硬度:hb220-260硬化层深度:0.8-3mm直线度:0.15mm/以下1000mm镀铬层厚度: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. 不锈钢直管阀芯:不锈钢直管阀芯具有高耐腐蚀性、高强度和高耐磨性，以保持其性能。适用于水、化工、蒸汽、海水等易发生氧化的场合。材质:sus404c, sus304硬度:hrc602硬化深度:0.8-3mm表面粗糙度:ra0.10 -ra0.35m直线度:70m/ 1000mm以下镀铬厚度:3m-5m。轴外径公差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

　　镀铬空心轴:由于空心结构，空心轴大大减轻了重量，简化了结构。它的内部适合于刺穿测量线，压缩空气，添加润滑油，或用于机械臂。公司还承接各种非标直线光轴(包括直径、公差、材质等)的定制及各种轴类加工。

　　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.
