Features and applications of CK45 chrome-plated rods:

When the chrome-plated rod is subjected to external load movement, it continuously bears the action of the loop stress on the rolling surface or the ball. When the stress reaches a certain limit, fatigue damage occurs on the rolling surface, and a part of the surface produces scale-like peeling. This phenomenon is called surface spalling.

  • The life of the chrome-plated rod refers to the number of revolutions of the chrome-plated rod until the initial surface peeling due to rolling fatigue of the material occurs on either side of the rolling surface or the ball.
  • The life of chrome-plated rods, even if the chrome-plated rods manufactured by the same method are used under the same motion conditions, their life will be quite different.
  • The surface of the chrome-plated rod is processed by special grinding and hard chrome electroplating technology, and then mirror-polished. It has abrasion resistance and corrosion resistance. At the same time, due to its hardness, it can also extend the service life of ordinary precision mechanical instruments.

The high-frequency chromium-plated rod is made of ck45 steel and is widely used in machinery and equipment. The hardness of the ordinary optical axis (piston rod) is about 20 degrees, and the hardness of the high-frequency hardened optical axis (quenched/tempered optical axis) reaches 55 degrees. The left and right sides can be used in conjunction with linear bearings, shaft support seats or aluminum brackets. The wear-resistant and corrosion-resistant products promote the high-precision, high-speed, high-competitiveness, and durability of the entire machine, and greatly improve the performance of the equipment. Used in packaging and printing machinery, woodworking machinery, fitness equipment, power tools, textile machinery, light industry machinery, automation equipment and other industrial machinery and supporting equipment.
