The chrome plated rod has undergone chrome plating treatment, including chrome plated soft shaft, chrome plated hard shaft, and quenching and tempering shaft. Usually plated with hard chromium, the surface hardness and wear resistance are much better than ordinary steel bars; The polished rod has only undergone polishing treatment, which may be polishing the original rod or polishing after chrome plating, but it has good wear resistance and better smoothness than the polished rod.

The performance of the chrome plated optical axis: manufactured using advanced processes such as precision cold drawing, precision grinding, and high-precision polishing, all technical indicators meet and exceed national standards. It has high strength, strong wear resistance, corrosion resistance and other properties. Commonly used in textile machinery, glass machinery, printing machinery, woodworking machinery, sports equipment and other machinery industries.

Chromium plated linear flexible shaft: Chromium plated linear flexible shaft can be directly used for fitting precision piston rods and some self-lubricating bearings due to its thick chromium plating layer. Due to its moderate hardness, it has been applied in many fields.

The conventional specifications of chrome plated rods mainly include Φ 3 Φ 4 Φ 6 Φ 8 Φ 10 Φ 12 Φ 13 Φ 14 Φ 15 Φ 16 Φ 17 Φ 18 Φ 20 Φ 22 Φ 25 Φ 28 Φ 30 Φ 32 Φ 35 Φ 38 Φ 40 Φ 45 Φ 50 Φ 55 Φ 60 Φ 63 Φ G5 Φ 70 Φ 75 Φ 80 Φ 85 Φ 90 Φ 100 Φ 120 high-frequency.

The chrome plated rod is divided into two major series, namely LM and LME series. Its code name LM series is used in Asia, Southeast Asian countries, Japan, South Korea, China, etc. Based on metric dimensions, the outer diameter tolerance of the straight axis used is generally h7. The LME series is commonly used in Europe, the United States, Germany, Italy and other regions. Based on imperial dimensions, there are also metric dimensions, and the outer diameter tolerance of the straight axis used is generally g6. The structural characteristics of the two series are roughly the same, except for differences in size and aperture tolerances.

Do not use the heat treatment process of carburizing and quenching for 45 # steel. After quenching and tempering, the parts have good comprehensive mechanical properties and are widely used in various important structural parts, especially connecting rods, bolts, gears, and shafts that work under alternating loads. But the surface hardness is low and not wear-resistant. Quenching and surface quenching can be used to improve the surface hardness of parts. The 12 millimeter diameter chrome plated rod is made of 45 # steel material with surface chrome plating, and is widely used in mechanical equipment. The hardness of ordinary optical shafts (piston rods) is about 20 degrees, and the hardness of high-frequency hardened optical shafts (quenched/quenched and tempered optical shafts) is about 55 degrees. It can be used in conjunction with linear bearings, shaft support seats or aluminum brackets. The product's wear resistance and corrosion resistance promote the high-precision, high-speed, high competitiveness, and durability of the entire machinery, Significantly improved equipment performance; At the same time, it has a considerable price advantage. The 12 millimeter diameter chrome plated rod and high-frequency precision linear optical axis are a new type of standard parts that have gradually been adopted by advanced mechanical industries around the world in recent years. It is widely used in electronics, packaging, textiles, printing, engineering, transportation, steel, mining, hydraulic cylinders, cylinders, operating rods, adjustment rods, and linear motion.
