What does the 0.25mm size mean for my engine?

The 0.25mm (or .010 inch) designation means these bearings are slightly larger than standard size. This is used when the crankshaft journals have been machined undersize to remove wear or damage. Always confirm your crankshaft journal size before ordering bearings.

What is the bimetal aluminum base construction?

This refers to the material used in the bearing shell. A bimetal construction typically involves a steel backing for strength, with an aluminum-based alloy overlay that provides good conformability and wear resistance, along with excellent compatibility with engine oils.

Does this set include all the main bearings needed for the engine?

Yes, this is a main bearing set, which includes all the necessary main bearings to support the crankshaft in your Mazda's engine.

About this part

Product Details

Built with a bimetal aluminum base, this main bearing set from King Engine Bearings is made specifically for your 1979-1985 Mazda GLC with E3 or E5 engines. Main bearings are critical components that support the crankshaft within the engine block, allowing it to spin smoothly while handling immense loads. When rebuilding or repairing your engine, using well-made bearings ensures proper oil clearance and long-term reliability.

This set is 0.25mm (.010 inch) larger than standard size, which is important if your crankshaft journals have been machined undersize during a previous rebuild or repair. The bimetal construction offers a good balance of strength and conformability, helping to maintain oil film integrity under pressure. King Engine Bearings is a well-known name in engine bearings, and this set is designed to meet the demands of your GLC's engine.
