Standard Precision Motor Shaft

The Guanshuo’s China Standard precision motor shaft of a general-precision motor is made of conventional 45 # steel /40Cr base material and undergoes quenching and tempering heat treatment. It does not require high-precision grinding or special processes, and the manufacturing cost is controllable, which is suitable for the cost control requirements of bulk purchasing of general motors. The tolerance of the key mating surfaces (bearing positions) is IT6 - IT7, and that of the non-mating sections is IT8 - IT9. The shape and position tolerances meet the requirements of conventional transmission and are suitable for the precision threshold of ordinary motor procurement.

Steel No. 45 quenched and tempered (HRC28-32) ensures strength and toughness. 40Cr is suitable for heavy-duty scenarios. The processing flow is standardized, and the quality stability is high, meeting the reliability requirements for industrial-grade motor procurement. G6.3 (≤1500rpm), G2.5 (1500-3000rpm), effectively control vibration and noise, suitable for the operation requirements of medium and low-speed equipment procurement such as fans, pumps, and ordinary gear motors. It supports basic anti-corrosion treatments such as blackening, phosphating, and simple chromium plating, meeting the protection requirements for dry and indoor conventional working conditions without the need for additional anti-corrosion costs.

Product Parameter (Specification)

Product Feature And Application

Standard precision motor shaft are suitable for procurement scenarios with medium precision requirements, a focus on procurement costs and the stability of batch supply, and no need for precise transmission. The base material (45 # steel /40Cr) and surface treatment method can be selected according to the motor power, load, and environmental requirements, fully covering the procurement needs of conventional motor shafts It is a key component with high cost performance that balances cost, universality and reliability.
