Installation Errors Part 4 – Hold Down & Jacking Bolts

| | | | |

By on September 20, 2018

Correct fastener torque is important for proper assembly of rotating machinery components to machine bases. Proper torque insures that the fastener will perform as designed. This will in turn help your machine to perform as designed. Hold down bolts and jacking bolts are typically manipulated while performing a precision shaft alignment. These are often the […]

Installation Errors Part 3 – Proper Torqueing of Hold Down Bolts

| | | | |

By on June 27, 2018

One of the most under-rated procedures of the precision shaft alignment process is the TIGHTENING SEQUENCE of the hold down bolts on the movable machine. Also, tightening the bolts to proper torque specifications is many times considered unnecessary and is just not typically done. Tightening sequence and proper bolt torque are critical to the performance […]
