Rectorseal M00660 Unit Bearing Motor Replaces Tyler 51255320

Product Description

The RECTORSEAL M00660 is a single-phase shaded pole unit bearing motor rated at 5 watts maximum output. It runs at a nominal speed of 1550 RPM with an operational range of 1350 to 1900 RPM, making it suitable for low-torque fan and blower applications in refrigeration and HVAC equipment. The motor features a sleeve bearing design, TEFC enclosure, and built-in thermal protection. Clockwise rotation and single-speed operation simplify direct replacement in OEM applications. Licensed refrigeration and HVAC technicians typically handle installation in commercial display cases and similar equipment.

This unit bearing motor is intended for use in refrigeration display case fan assemblies and similar light-duty evaporator or condenser fan applications. It is a direct replacement for Tyler part number 51255320, which appears in commercial refrigeration cases. Single-phase power supply is required. The compact unit bearing form factor is common in reach-in and open-deck refrigerated display equipment found in grocery and foodservice environments.

Key Features
