Main bearing MB5259XP STDX HONDA A-series, B-series, K-series

King Bearing XP bearings are characterized by the use of extremely advanced metallurgy technologies.

They have been specially designed for long-term work under load in high-performance engines.

The patented pMax Black technology was used in the production of XP shells.

pMax Black are three-layer bearings with increased hardness by 24% compared to other competition bearings.

This technology in combination with advanced bearing geometry makes them an ideal solution for highly stressed engines.

The bearings are available in several sizes:

• STDX -0.025 mm (looser than nominal)
• STD +0,000 mm (nominal)
• +0.025 mm (narrower than nominal)
• +0.25 mm (first shaft grinding)
• +0.50 mm (second shaft grinding)
