CK45 chrome plated hollow piston rod is a precision component commonly used in hydraulic and pneumatic systems. It is designed to transmit force, withstand high loads, and provide reliable performance in demanding mechanical environments. The CK45 material, equivalent to 45# carbon steel, offers a excellent balance of strength, toughness, and machinability. The hard chrome plating significantly enhances surface properties, making it highly resistant to wear, corrosion, and friction.
1、A hard, smooth chrome plating surface provides excellent wear resistance. Continuous movement and small to constant friction within hydraulic cylinders make this a near essential property for hollow piston rods.
2、The more shiny, reflective surface of the chrome piston rod (functional and aesthetically) enhances the overall look of the hydraulic component itself.
3、The previously mentioned hardness and all related improved surface properties can push the effective load bearing capacity of the rod beyond what unchrome plated rods are capable of.
4、Various forms of chemical resistance are also achieved through chrome plating.
1、Advanced automatic production lines and to a point, inspection equipment - efficiency is paramount.
2、A perfected management system leads to near perfect quality control; piston rod factories (ours included) put all customer requirements first.
3、Domestically and internationally, our hollow piston rods have built a good reputation (Europe being a prime example of successful, long term exportable work).
4、Our staff are all part of that process - small or large scale, we are all about quality and/or serviceable production.
5、We are and always will be, a true factory of hollow chrome piston rods.
