Regarding the BWED121-1003-0.55KW cycloidal pinwheel reducer you are asking about, according to the general manufacturing standards and industry specifications of this series of equipment, the material of the output shaft is usually as follows:
1. Core material: 45# steel (45# carbon structural steel)
This is the most mainstream and versatile material for the output shaft of cycloid reducer.
Reason: 45# steel has good comprehensive mechanical properties. In order to adapt to the high torque output of the reducer, the shaft is usually quenched and tempered (quenching + high temperature tempering) to obtain higher strength and toughness to prevent breakage or deformation under heavy load.
Applicability: For reducers with a frame size of BWED121 (small and medium-sized specifications) and equipped with a 0.55KW motor, 45# steel can fully meet conventional industrial transmission needs.
2. Special customization: 40Cr (alloy structural steel)
Although standard products mostly use 45# steel, under some specific working conditions, manufacturers may use 40Cr.
Scenario: If your reducer is used for heavy loads, large impact loads, or extremely high requirements for shaft strength.
Characteristics: 40Cr has better hardenability than 45# steel and can withstand greater loads after treatment.
