Crankshafts are one of the most important parts of a textile loom.

Material
As a critical component of textile looms, the performance of crankshaft ultimately directly impacts the service life of the textile loom. Because the crankshaft needs to bear a heavy load and changing torque, choosing the right production materials is a necessary step, and we choose materials based on actual application needs. Typical materials 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 specialize in designing and manufacturing high quality crankshafts, is a recognized precision crankshaft manufacturer and textile loom crankshaft supplier, and providing custom machining service. There are crankshafts like alloy steel crankshaft, cast iron crankshaft, carbon 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 textile machine crankshafts can be made based on customer required materials and drawings to meet client demands.
