  • Our bearings are manufactured to our customers’ specific requirements, and can be configured in many ways. We can produce these bearings for shafts ranging from 8 inches to over 40 inches.

  • We regularly produce these bearings in weights up to and over 7,000 pounds for combat use. Structures can be verified to meet the most stringent shock requirements and are designed to continue operating in flooded machinery compartments.

  • We centrifugally cast our babbitted bearings in house and test them using our NAVSEA and ABS approved procedures. Utilizing our in-house NDT processes, we can ensure the successful operation of our equipment, even in the harshest of operating conditions.

  • Self-aligning design allows for shaft deflection while minimizing bearing wear and tear.
