ACL Bearings 8B818S-STD Standard Connecting Rod Bearing Set

The ACL Bearings 8B818S-STD is a standard size connecting rod bearing set designed to provide reliable performance for engine rebuilds and restorations. ACL Bearings manufactures high-quality engine bearings that serve both OE replacement and performance applications worldwide.

Construction and Materials

This connecting rod bearing set features tri-metal construction with hardened steel backing for improved support and retention within the connecting rod housing. The bearing lining is engineered to provide proper load distribution and oil film formation under normal operating conditions. ACL's manufacturing process ensures tight wall thickness tolerances to help maintain consistent bearing clearances during assembly.

Standard Size Specifications

The "STD" designation indicates this bearing set is manufactured to standard (original equipment) size specifications for the crankshaft journal diameter. These bearings are intended for use with crankshafts that are within factory specifications and have not been ground undersize. The bearing shells feature proper crush for secure retention in the connecting rod housing.

Design Features

• Tri-metal bearing construction for durability
• Hardened steel backing shells for improved bearing support
• Precision manufactured to maintain consistent oil clearances
• Standard size fits factory specification crankshaft journals
• Chamfered bearing edges to accommodate crankshaft fillet radii
• Proper bearing crush for secure housing retention

Application

This bearing set is designed as a direct replacement for worn or damaged connecting rod bearings during engine overhaul. Proper measurement of crankshaft journals and connecting rod bores is essential before installation to ensure appropriate oil clearances are achieved. ACL recommends following OEM torque specifications when installing connecting rod caps.

Note: Always verify bearing-to-journal clearances using precision measurement tools before final assembly. Proper lubrication during installation is critical for bearing longevity.
