shaft Collar is an important component in the mechanical industry, used to connect shafts and bearings, transmit motion and force. Therefore, the correct selection and use of the collar is very important. The following introduces the surface treatment technology and its application of the shaft ring.
1、 Surface treatment technology
The surface treatment technology of the shaft ring includes nickel plating, chromium plating, tin plating, copper plating, etc. Different surface treatment techniques have different effects on the performance and lifespan of the shaft ring.
plate with nickel
Nickel plating is a common surface treatment technique that can improve the corrosion resistance and wear resistance of shaft rings. After nickel plating, the collar can better resist the corrosion of water and oxygen, and can maintain its luster and color for a longer time.
Chrome plating
Chromium plating is a more wear-resistant and harder surface treatment technology. Compared to nickel plating, chromium plating can better resist corrosion and oxidation, and can maintain a longer gloss. Chromium plating is commonly used in applications that require high hardness and wear resistance.
Tin plating
Tin plating is a surface treatment technique used to connect shafts and bearings. It can increase the contact area of connectors, reduce friction coefficient, improve sealing and anti-corrosion performance.
copper plating
Copper plating is a relatively valuable but long-lasting surface treatment technique. It can increase the contact area of connectors, reduce friction coefficient, improve sealing and anti-corrosion performance.
2、 Application
Different surface treatment techniques are suitable for different types of collars and can improve their performance and lifespan.
long life bearing
Long life bearings usually require high corrosion resistance and wear resistance, and surface treatment technologies such as nickel plating and chromium plating can meet these requirements. These surface treatment technologies can improve the service life of bearings and reduce maintenance costs.
Heavy duty, high-speed bearings
Heavy duty and high-speed bearings require higher hardness and wear resistance, and surface treatment technologies such as chromium and nickel plating can meet these requirements. These surface treatment technologies can improve the service life of bearings and reduce maintenance costs.
Precision instrument parts
Precision instrument parts require high-precision and high-quality surface treatment, and surface treatment technologies such as nickel plating and chromium plating can meet these requirements. These surface treatment technologies can improve the smoothness and service life of bearing parts, reduce mechanical wear and noise.
