Top Quality Certification

Duraline products are tested and certified by the finest quality and safety agencies ensuring that every Duraline motor will be a long lasting reliable workhorse for whatever application required.

Rugged High Temperature Insulation

Duraline motors are double vacuum impregnated with high temperature "H" class non-hygroscopic varnish. Our motors are fitted with spike resistant phase paper between each phase. This ensures inverter compatibility and long term reliability.

High Quality, High Durability Bearings

All our motors are equipped with the highest quality bearings for extremely long life and quiet operation. All of our bearings contain high carbon chrome steel rolling elements and premium lubricants. Our motors use oversized bearings on both the drive and the opposite drive end.

Peace of Mind Guarantee

If something does go wrong with your motor you are protected by our Top Guardian guarantee. If one of our motors fails due to workmanship or material failure, Duraline will repair your motor or ship you a replacement.
