Internal combustion engines employ plain (sliding) bearings instead of rolling bearings due to their ability to withstand shock and ruggedness against grime. They are also more cost effective and can be packaged in to the tight confines of increasingly compact IC engines. The disadvantage is higher friction level. They usually comprise of a steel back coated with the bearing material, usually an alloy of Al-Sn or Cu-Pb-Sn. Since bearings are designed to protect the crankshaft, connecting rod, camshaft and the other shafts they are assembled on, they have a wide variety of failure modes. Hence precise design, correct material choice and consistent manufacturing quality are key to ensure bearings of acceptable quality, which is why Garima Global sources its AutoGRACE® brand big end bearings, main bearings, camshaft bushes, small end bushings and other engine bearings exclusively from the leading OEM and aftermarket factories of engine bearings in India.
