Just revised is this Cost Justification Worksheet (CJW) For Motors. Yours free and downloadable, the Excel module identifies energy and operational savings a plant can attain through use of bearing isolators.
For anyone involved in maintenance, repair, and operation of motors — the tool offers elements that can also be used with pumps, turbines, fans, gear boxes, conveyors, shafts, VFDs, machine tool spindles, or other rotating equipment.
CJW offers an easy-to-configure ROI Calculator. Simply supply number of motors, current costs to repair, and other pertinent performance data. The worksheet allows you to calculate plant return on investment, factoring-in use of bearing isolators. This includes benchmarks of current repair costs and ways to increase rotating equipment reliability. CJW also includes such information as accumulated savings, total investment, net return, data for life-cycle costing, use of more efficient motors, as well as net costs to run motors more efficiently.
Inpro/Seal Bearing Isolators are noncontact labyrinth seals comprised of a unitized rotor and stator that do not contact one another. They do not consume energy or wear out. Protected bearings have run 150,000 hr (17 years) or more.
