Which type of misalignment occurs when shafts are parallel but not on the same axis?

• A. Angular misalignment
• B. Offset misalignment
• C. Radial misalignment
• D. Vertical misalignment

Answer: (B)

Offset misalignment occurs when two shafts are parallel to each other but not aligned along the same axis, leading to a lateral displacement between the two. This type of misalignment can create additional stresses on bearings and couplings and can lead to increased wear and potential failure if not addressed. Understanding offset misalignment is crucial for ensuring proper alignment in various mechanical systems to maintain efficiency and reliability. In contrast, angular misalignment refers to a situation where the shafts are not parallel because they are at an angle to each other. Radial misalignment, on the other hand, involves the shafts being out of alignment in a vertical or sideways manner but still on the same axial line, which differs from the offset condition. Vertical misalignment specifically pertains to the vertical alignment of shafts, regardless of whether they are parallel, which does not describe this scenario accurately.
