King Engine Bearings MB5736XPC0.25 Performance Main Bearing Set Undersize - 0.25mm

The King MB5736XPC0.25 features a nano-composite polymer coating applied over the pMaxBlack overlay, enhancing wear resistance without changing the bearing's original precision wall thickness dimension. This pMaxKote is a nano-composite polymer coating applied over the pMaxBlack overlay at the King factory as part of the bearing manufacturing process, enhancing wear resistance without changing the bearing's original precision wall thickness dimension.

Advanced XPC Series Technology:

• Proven to protect bearings during metal-to-metal contact, as well as from the erosive effects of cavitation
• Contains ceramic nano-composite particles that function as a fourth layer that provides superior build protection
• pMaxBlack combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity
• pMaxBlack overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process
• Helps with oil starvation and periods of marginal bearing lubrication

Precision Manufacturing:

• Outperforms the industry's wall thickness tolerance, ensuring the least thickness variation shell-to-shell
• Bearings intended for coating are marked with a 'C' stamp and optimized for coating from the beginning of the manufacturing process
• Coating process is completed completely in-house at King

The 0.25mm undersize specification makes these bearings ideal for engines with crankshafts that have been machined undersize during rebuilding or reconditioning.
