XSD Ultra 841 Extra Severe Duty Motors

Four-point cast-in lifting lugs for easy and safe mounting.

Permanently labeled, non-wicking Class H leads make connections and installation easy.

Non-sparking corrosion-resistant fan is quiet and energy efficient.

Centered stator core/frame design enables the conversion to F2 mounting.

Lead gasket and conduit box cover gasket prevent moisture and contaminants from entering the motor.

Grounding terminal in conduit box adds to safety during installation and service.

Proven Bearing System

  • Single shielded oversized bearings on every motor.
  • Sealed bearing system that is 100% regreasable, IP55 and above protection
  • 130,000 hr L10 bearing life on 4 pole motors
  • Fully charge lubrication system before assembly.
  • Suitable for 104 to 248 degrees F temperatures.
