Bearing clearance is one of the fundamental aspects of engine building and one that continues to spark debate and divisive opinions—and as with everything from nitrous systems to eating chocolate, ...

Engine bearings play a vital role in the proper functioning of any vehicle’s engine. Their primary duty is to lessen the friction between moving parts, thereby preventing erosion and promoting ...

The primary job of an engine bearing is to establish a low-friction interface for a rotating shaft. Most bearings today are half-round assemblies used around crankshafts, for example. While you might ...

Engine bearings do many things. They support moving parts like crankshafts and connecting rods, but they also play a role in determining an engine's oil pressure and protect the crankshaft from being ...

Nittos, zero rub, and pure truck envy, until the engine tells a different story. This 2025 Tundra owner thought he had the ...

The main bearing secure the crankshaft in its place. The largest number of main bearings a crankshaft can have is one more than the number of cylinders, but it can have one less bearing than the ...

To improve both the durability and reliability of the main bearing, and also to reduce friction, a technique was developed to measure transient sliding friction of main bearings in a firing engine.
