Babbitted bronze bearings
Magnolia Metal Corporation manufactures precision babbitted bronze bearings using a modernized foundry and machine shop process built for consistent quality and repeatable results. We use Magnolia Grade II Babbitt made from virgin materials for our standard babbitted bearings, and special babbitt alloys are available upon request when your application requires a different lining material.
Precision Babbitted Bearings Built for Fit and Performance
Babbitted bronze bearings combine a strong bronze shell with a babbitt lining selected for bearing performance in demanding equipment. Our process is designed to deliver accurate fit, proper bearing clearance, and consistent crush so the bearing conforms correctly to the housing or connecting rod bore once installed.
We produce babbitted bearings using centrifugal casting equipment capable of spinning 3 inch to 24 inch bore diameters with a maximum length of 26 inches. Babbitt thickness is determined by the application so the lining is matched to your load, speed, lubrication, and service conditions.
Bearing Crush and Quality Control
Bearing crush is the amount the bearing shell protrudes above the exact centerline of the main housing or connecting rod bore before the cap is torqued down. When compressive force is applied at the split line, the crush helps the bearing conform to the housing, support alignment, and maintain proper seating.
Precision ground fixtures are used to machine bearing crush and verify final dimensions. Final inspection is performed with the bearing placed in precision ground fixtures to help ensure proper bearing clearance and crush prior to shipment.
