Reliable Foundations for Pumps and Systems | Pumps & Systems

Mar 08, 2012 · If R = 0.8 (bottom), an AF of 7.5 (off the chart) requires all loads be amplified by 7.5. That includes nearby motors, bearings, shafts, bolted joints, piping, and welds, etc.; if you sized a bearing to support a 2-ton load and it is operating with a 15-ton load at a rated speed, then it will fail and result in high maintenance.
