Main bearings STD Mazda PC, TC 985cc ACL ACL-5M1167-STD

Main bearings STD Mazda PC, TC 985cc ACL ACL Race bearings are designed to work in the most extreme conditions and the most demanding engines. Thanks to many years of experience in the production of bearings, each set is perfectly matched to the engine. The advanced technological process allows the bushing to adjust to deformations. at high revs and helps in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them an ideal solution for highly stressed engines. Most bushings are also available in several other dimensions: STDX -0.025 mm (looser than nominal) STD +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0.50 mm (second shaft grinding)
