4 Fabric main bearing shells from ACL are used in engines where the engine speed is increased, increased boost pressure, increased compression, turbo conversions or in engine concepts where high oil temperatures are expected.
The G60 engines in particular generally stand out with high oil temperatures! The ACL bearing shells offer more safety for the engine block / crankshaft. Due to the 180° oil groove, the oil pressure in the complete engine remains stable, and sufficient oil also reaches the cylinder head from the fuselage engine.
ACL RACE 4 material bearings:
1. lead, tin, copper, sliding layer for increased permanent load
2. nickel barrier layer
3. copper lead lining
