Taiho Micro grooved main bearings are highly innovative, high-performance engine bearings with fine grooves provided in the bearing inner wall. These bearings break the tradition of absolute flatness in bearings.

MGB (Micro-Grooved Bearings) are engine bearings that have numerous shallow circumferential grooves covering their surface (Pitch: 0.1 to 1.0mm Groove depth: 1 to 10µm), much like a music record disk. Notwithstanding the conventional concept in that the surface should be smooth, the Microgrooves greatly contributes to engine noise and vibration reduction.

MGB have various and superior performance characteristics and high potential, such as in vehicle comfort improvement, environmental control solutions including low fuel consumption and light-weight vehicle realization.
