Our chrome plated shafts gained good reputation for features as bleow.
a. The hard chromed surface confers the important properties of corrosion resistance and wear resistance; it is also very smooth and therefore has a low coefficient of friction. Not least of all, it has an attractive and durable decorative appearance.
b. Carbon steel balances durability, hardness, and wear resistance using formability, weldability, and durability;
c. High precision tolerances, which ensures when used to make hydraulic piston shafts, it can fit the cylinder precisely.
d. High performance of strength: The yield strength of chrome plated shafts can be 75000 psi up to 100000 psi, depends on the material and heat treatment method.
e. Good Hardness: the surface hardness attaining HV850 minimal and upward, which not only help improve wear resistance but also help extend the life span of these chrome plated shafting, thereby helping the consumer save the cost.
f. Excellent smooth surface: The surface roughness of our factory’s hard chrome plated shafting is around Ra0.2μm(8 Ra), max. Ra0.4μm (16 Ra).
Our factory, a professional supplier of chrome plated shafts, ensures safe transportation by providing reliable packaging methods.
All the chrome plated shafts will be oiled by the anti-rust oil before delivery. Our standard packaging consists of a cardboard and rope or a wooden case. To preserve the smooth exterior diameter of the chrome bars, each bar is placed in a cardboard (paper tube) and then wrapped with ropes to form a bundle. Alternatively, the bars with their cardboard packaging can be placed in wooden boxes for added protection.
Chrome Plated Shaft: Applications
Chrome plated shafts are used in a variety of applications due to their strength, durability, and resistance to corrosion and wear. They are commonly used in various applications, including:
-
- Hydraulic cylinder rods
- Shafts for various machines
- Pneumatic cylinder rods
- Transmission eccentric shafts for horizontal forging machines
- Crankshafts for forging presses
- Conveyor rollers
- Bearings and bushing
- Agricultural equipment components
- Material handling equipment components
- Food processing equipment components
- Industrial automation equipment components
- Mining equipment components.
In addition to solid steel rods, chrome plated shafts can also be made from chrome plated hollow bar.
