摘要: A clutch bearing (34) for a transportation refrigeration unit includes one or more rolling elements (38) supportive of one or more components of an electromagnetic clutch for a transportation refrigeration unit, and a plurality of bearing races (36) configured to retain the one or more rolling elements. The bearing races include a coating of thin dense chromium to reduce corrosion and/or damage of the clutch bearing. A transportation refrigeration unit includes a power source (12) and a blower (32) of the transportation refrigeration unit. An electromagnetic clutch (14) is operably connected to the power source and the blower (132) and includes a rotor (16) positioned at a central axis and an armature (18) positioned at the central axis and having an axial air gap (22) to the rotor when the clutch is in a disengaged position. A clutch bearing is located at the central axis and is supportive of the rotor.
