What does 0.50mm oversized mean for these rod bearings?

The 0.50mm designation means these bearings are undersized by half a millimeter (approximately 0.020 inches). This size is used when the crankshaft journals have been machined down to a matching undersize to correct wear or damage, ensuring proper clearance and oil film.

Are these bearings sold individually or as a set?

This is a set of rod bearings, meaning it includes all the bearings needed for the connecting rods on your engine. This ensures you have the correct quantity and size for a complete installation.

What is the primary function of rod bearings?

Rod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear by allowing the rod to rotate smoothly around the crank journal, all while maintaining a thin film of oil.

Product Details

You get a full set of 0.50mm oversized rod bearings in this kit, which means one box handles the critical bearing replacement for your engine rebuild. These ACL bearings are made for the 1597cc to 1997cc engines found in your 1989-1991 Hyundai Sonata. Rod bearings are crucial for reducing friction between the connecting rod and the crankshaft, and replacing them during an engine overhaul is standard practice to ensure longevity and proper oil flow.

ACL has been making engine bearings for a long time, and these are well-built replacements. The 0.50mm undersize means they are designed to be used when the crankshaft journals have been machined down by 0.020 inches (0.50mm) to clean up wear or damage. This size is common when rebuilding an engine that has seen significant mileage or has experienced lubrication issues. Installing these bearings correctly with the proper clearances is key to a healthy engine.
