Product Overview
▔▔The MSK040B is available with different winding, encoder, connector and brake configurations. Therefore, "MSK040B" alone is not enough to identify the exact replacement in many applications. The complete type code should be checked before purchasing. Bosch Rexroth documentation lists MSK040B variants including 0450 and 0600 windings, with different encoder and brake options.
Key Advantages
▔▔The MSK040B uses the compact 040 motor size and has a short B-length housing. Bosch Rexroth drawings show a basic MSK040B motor length of approximately 155.5 mm for the standard configuration, while encoder and brake combinations can change the overall length.

FAQ
▔▔Can MSK040B-0450 and MSK040B-0600 be exchanged directly?
They should not be assumed to be direct replacements. Although both are MSK040B motors, they have different winding characteristics, current requirements and maximum speeds. The complete motor and drive configuration should be checked before replacement.
Does the MSK040B have a brake?
It depends on the complete ordering code. MSK040B motors are available in configurations with and without a holding brake. A brake-equipped configuration can have a 4 Nm holding torque.
