Crankshafts are one of the most important components to an air compressor. It is primarily used as the transmission component to invert rotary motion to a rectilinear motion. It is also the transmissions structure for a piston compressor, centrifugal compressor, and other compressors.

Materials
As one of the most crucial parts of a compressor, and with an appearance that directly influences the work life of the compressor, it is vital to choose crankshaft material that is capable of bearing a heavy load and changing torque. Due to that, users must choose the material based on the actual application needs of the compressor. Traditional choices are as follows:

Nodular cast iron
a. The yield strength and tensile strength of nodular cast iron can reach up to 600-900MPa.
b. It's easy to produce a crankshaft using nodular cast iron, especially as nodular cast iron is generally inexpensive.
c. The nodular cast iron features an excellent shock absorption, abrasion resistance and no cracks.

carbon steel
a. Quality carbon steel is known for its strength and capability to meet normal demands. It costs less than alloy steel, and has a better ductility than nodular cast iron.
b. Quality carbon steel also features an excellent plasticity, physical performance, chemical performance and mechanical performance.

Alloy steel
a. Alloy steel has better tensile strength, yield strength and ductility than nodular cast iron and quality carbon.
b. Alloy steel also has an outstanding strength and impact resistance. Compared to quality carbon steel, it has a better physical, chemical and mechanical performance.

Features
1. We have a professional CNC crankshaft grinder and CNC cylindrical grinder, with the eccentric distance featuring an accuracy of 0.01mm and the cylinder accurate to 0.005mm.

2. Our crankshafts are known for their rigidity, strength and impact resistance.

3. Crankshaft materials include alloy, and a roughness of Ra0.02 after polishing, giving it an excellent wear resistance and lubricity.

4. Nazhen owns and operates numerous professional detection equipment sets, including a trilinear coordinates measuring instrument, contour graph and rough meter in order to carry out strict detection processes for the degree of parallelism of the crankshaft, torsion resistance of the crankshaft and coaxiality of the two crank throw. This ensures all crankshafts rotate smoothly and with no noise, vibrations or shaking, thus ensuring a long service life for the compressor.

NAZHEN is a recognized precision crankshaft manufacturer and air compressor crankshaft supplier, specialize in designing and manufacturing high quality crankshafts and custom machining service. There are crankshafts like cast iron crankshaft, carbon steel crankshaft, alloy steel crankshaft, forged crankshaft for choose. As we use complete manufacturing and testing equipment, we are committed to providing high quality precision crankshafts and solutions, the air compressor crankshafts can be made based on customer required materials and drawings to meet client demands.
