Product Description
A marine turbocharger bearing must operate at the intersection of extreme heat and massive mechanical load. At Sourcing Marine, our bearings are sourced from manufacturers who utilize vacuum-degassed steel and precision-cast babbitt layers. This ensures that even under the thermal expansion of a full-load exhaust flow, the bearing clearances remain within microns of the original design specification.

Technical Advantages of Sourcing Marine Bearings
- Anti-Fretting Design: Our bearing shells feature specialized surface treatments to prevent fretting corrosion in the bearing housing—a common cause of turbocharger failure.
- Lubrication Precision: We ensure that every bearing—whether it is a “floating bush” or “fixed” type—has optimized oil-entry ports to maintain a stable oil wedge, preventing metal-to-metal contact during rapid load changes or “surging” events.
- Strict Quality Verification: All bearing units undergo Ultrasonic Testing (UT) to check for bonding integrity between the lining and the backing, alongside 3D Coordinate Measuring Machine (CMM) inspections for dimensional perfectness.
