Main bearings 0.75 Nissan 1970-1972 1189-1299cc ACL Aluglide ACL-3M2637A-75

Main bearings 0.75 Nissan 1970-1972 1189-1299cc ACL Aluglide ACL Race shells 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 be adjusted to deformation at high speeds and helps in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them ideal for heavily 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)
