Straight 1, ordinary linear optical axis (sf): Due to ordinary linear optical axis linear bearings in contact with the opposite point so the surface hardness of the ordinary linear optical axis of demanding, so materials and heat treatment method is very important. Material: suj2 (fairly) GB gcr15 hardness:. Hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness: 70um / 1000mm or less Shaft diameter tolerance g62, chrome linear optical axis (sfc) : chrome linear optical axis is based on ordinary linear optical axis of a layer of hard chrome plating, suitable for long rust prone environment or a bad environment this axis widely used in industrial machinery, exercise apparatus automatic sliding systems section. Axis: suj2 (fairly) GB gcr15 hardness:. Hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness material 3, chrome straight shaft (rsfc): chrome straight shaft due to its thick chrome plating can be directly used precision rod and some of the self-lubricating bearings fit. Because of its relatively modest hardness have applied in many fields. Material: 45 # or 40cr or 2cr13 hardness: hb220-260 hardening depth: 0.8-3mm Straightness: 0.15mm / 1000mm or less chrome thickness: 0.02-0.05mm4, stainless steel linear shaft: stainless steel linear axis with high corrosion resistance, high strength and wear resistance in order to maintain its efficient operating performance. Therefore, it can be used in places prone to oxidation, such as water, chemicals, steam, water and so on. Material: sus404c, sus304 hardness: hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness 5, chrome-plated hollow shaft: chrome-plated hollow shaft due to the characteristics of its hollow structure, a large hollow shaft lessened the weight and simplify the structure, its interior is adapted to penetrate the measuring wire Foshan linear axis, compressed air, adding oil, or for the robot arm. The company also undertake all kinds of non linear optical axis (including diameter, tolerances, materials, etc.) are made and various shaft processing. Specific parameters and linear optical axis linear axis level! Linear Shaft materials: Gcr15 SUJ-2 (high-carbon steel) linear axis hardness: HRC higher than 60 * SFC: (SF + hard chrome plating) Features: 1 has corrosion resistance and rust resistance is easy to assemble 2. 3. interchanged easily run smooth, high precision silver steel support all use of large domestic steel quality carbon tool steel and medium carbon steel production, material quality assurance. This product is high-precision, high-Kyo, a mirror surface brightness. Surface finish products factory in Dongguan linear optical axis, the accuracy of the product, straightness, ovality can completely replace imported products. The finished product is in the annealed condition chrome linear optical axis to facilitate further processing customers. Processing range up to 4.3m diameter 0.8 to 65mm precision: straightness ≤0.1mm / m linear axis, ellipticity ≤0.002mm, diameter tolerance ≤0.005mm company is now mass production, quality and cheap, welcomed the purchase, The products are widely used in mold manufacturing, pneumatic, mechanical plastics, electronics and textile printing and many other areas, is ideal for a variety of precision cylindrical member of Applied Materials. Linear optical axis of the product a special surface grinding and hard chromium plating technology outside the grounds, and then mirror polished, wear clean, anti-corrosion properties, suitable for all kinds of cylinders, cylinder, piston rod, packaging, woodworking, textile, printing machinery, die-casting machines, injection molding machines, and other mechanical guide rod with the jack and so on.
