SHAFT - OEM ENCODER (Mitsubishi MB1011451)

A damaged encoder shaft can disrupt the feedback signal that controls motor speed and positioning. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1011451. The shaft serves as the mechanical link between the encoder rotor and the motor shaft, transmitting rotational motion directly. When the shaft wears or breaks, the encoder may produce erratic or no output, leading to uncommanded stops or incorrect positioning. In a typical usage context, a seized or bent shaft prevents the encoder from rotating freely, causing a loss of position feedback. Verify the serial number or application, then call (562) 693-7748. No weight is listed for this item.
