Air Compressor Crankshafts Manufacturing
We are one of the largest air compressor crankshaft manufacturers in China, we can OEM special air compressor crankshaft and also manufacture famous brand air compressors such as (Zell series, Bock series, Torino series) to provide crankshaft customization.
The crankshaft is one of the most important components of an air compressor. It is mainly used as a transmission component to convert rotary motion into linear motion. It is also the transmission structure of piston compressors, centrifugal compressors and other compressors.
We provide OEM service for high precision crankshaft, eccentric shaft, camshaft and other components for automotive air compressor, new energy vehicle air compressor, special air compressor and other fields.
Material
As one of the most critical components of a compressor, the appearance of which directly affects the life of the compressor, it is critical to select a crankshaft material that can withstand heavy loads and varying torques. Therefore, the user must select the material according to the actual application requirements of the compressor. The traditional choices are as follows:
Ductile Iron
A. Ductile iron has yield and tensile strengths of 600-900 MPa.
b. It is easy to produce crankshafts using ductile iron, especially because ductile iron is usually very cheap.
C. Ductile iron has excellent vibration damping, wear resistance, and no cracking.
Carbon Steel
A. High quality carbon steel is known for its strength and ability to meet normal demands. It costs less than alloy steel and has better ductility than ductile iron.
b. High quality carbon steel also has excellent plasticity, physical properties, chemical properties, and mechanical properties.
Alloy Steel
a. Alloy steel has better tensile strength, yield strength and ductility than ductile iron and high quality carbon.
b. Alloy steels also have outstanding strength and impact resistance. better physical, chemical and mechanical properties than high quality carbon steels.
Features
1. We have professional CNC crankshaft grinder and CNC cylindrical grinder with eccentricity precision 0.004mm and barrel precision 0.002mm.
2. Our crankshaft is famous for its stiffness, strength and impact resistance.
3. The crankshaft is made of alloy with roughness of Ra0.01um after polishing, which has excellent wear resistance and lubricity.
4、SPP INDUSTRY owns and has many professional testing equipments such as CMM, contour plotter, roughness meter, etc., to strictly test the parallelism of crankshaft, torsion resistance of crankshaft and coaxiality of crankshaft. Two crankshaft pitches. This ensures that all crankshafts rotate smoothly without noise, vibration or wobble, thus ensuring a long service life of the compressor
