The recommended design practice for steel lineshafting specifies that linear deflection should be limited to a maximum of 0.010 inches per foot of length. This value is crucial for maintaining the functional integrity and performance of machinery, as excessive deflection can lead to misalignment of connected components, increased wear, and potential mechanical failure.

By adhering to this limit, engineers can ensure that the lineshafting remains rigid enough to effectively transmit power without significant bending or deformation under load. This is particularly important in applications where precision and reliability are key, such as in drive systems and conveyor mechanisms. The 0.010 inches per foot standard reflects industry benchmarks aimed at preventing issues associated with deflection, thereby supporting optimal operation and longevity of equipment.
