Sealed Power A-Series aluminium-silicon bi-metal alloy engine bearings deliver greater seizure resistance than tri-metal materials, dramatically reducing or eliminating bearing wear in a wide range of automotive and truck engines. A-Series bearings are manufactured with silicon, which provides greater surface hardness for increased wear resistance. In addition, the silicon particles help polish the crank surfaces and bearing journals during engine operation, further reducing friction and related wear
