Century UB558 Refrigeration Motor 6W 115V 1550 Rpm

Product Description

The CENTURY UB558 is a shaded pole, single-speed refrigeration motor rated at 6 watts and 115 volts. It operates at 1550 RPM with a current draw of 0.36 amps on a single-phase, 60 Hz circuit. The motor uses a unit bearing frame and aluminum construction, making it compact and lightweight for tight equipment bays. It carries a Class B insulation rating, impedance thermal protection, and a 40 degrees C ambient rating. The totally enclosed, air-over design supports continuous-duty service in approved refrigeration and HVAC air movement applications. Licensed HVAC technicians and refrigeration service pros install this motor as a direct OEM-style replacement during scheduled maintenance or field service calls.

The UB558 fits residential and light commercial refrigeration equipment and HVAC air movement applications where a compact shaded pole motor is required. Clockwise rotation is measured from the lead end, opposite the shaft end. The threaded 1/4-20 shaft with a 0.415 inch shaft extension and 2 boss OSE 5-hole mounting pattern support accurate mechanical fitment. The 3.12 inch frame length keeps the footprint small for space-constrained installations. This motor is a direct replacement for the UB06CWLA2F motor and the D558 unit bearing blower motor.

Key Features

• 6 watt, 115 volt shaded pole motor with 1550 RPM single-speed operation
• Totally enclosed, air-over construction for continuous-duty service
• Class B insulation with impedance thermal protection and 40 degrees C ambient rating
• Clockwise rotation from lead end with threaded 1/4-20 shaft and 0.415 inch shaft extension
• Aluminum unit bearing frame with 2 boss OSE 5-hole mounting pattern
• UL recognized, CSA approved, and A2L compliant

Compatibility

The UB558 directly replaces the UB06CWLA2F motor and the D558 unit bearing blower motor. It is suitable for refrigeration and HVAC air movement equipment where voltage, speed, amperage, rotation, shaft size, bearing type, and mounting pattern match the existing motor.

Installation Notes

Installation should be performed by a qualified HVAC technician or refrigeration service professional. Disconnect and lock out all power to the equipment before removing the existing motor. Verify that rotation direction, shaft diameter, shaft extension length, mounting pattern, voltage, and amperage ratings match the replacement motor before installation. Consult applicable local codes and manufacturer equipment documentation before completing the repair.
