Cast Iron Unit Bearing motors are designed to exceed the life of the 2 Bearing motors used in the Residential and Light Commercial Refrigeration Industries.
The typical motor life of our Cast Iron Unit Bearing motors exceeds 80,000 hours. Alternatively, 2 Bearing Motors have historically been rated at 20-30,000 hours.
Unlike 2 Bearing Motors, our Unit Bearing motor has no Bearing to Shaft contact. This means virtually no bearing wear during the application run cycle.
