At the heart of your powerplant is the crankshaft, and this baby not only has to endure the entire rotating mass, but it is subjected to countless spin cycles at varying rpm. It's a tough life, which ...

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 ...

If you're one of those guys who take pride in building a high-performance engine, you know that one of the most important aspects of making that rotating mass live a long and powerful life is setting ...

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 ...

When you get right down to it, many of the tasks involved in building a race engine are mundane. It isn't too difficult to drop a piston in a hole or bolt up an intake manifold. And neither is ...

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 ...

A close look inside the crankcase to inspect the piston, connecting rod, and main bearing. This step reveals wear patterns and helps determine what can be reused, repaired, or replaced.

Wind turbines are fitted with multiple bearings that each wear differently. Today, larger stresses in larger turbines are testing conventional bearing designs, particularly in mainshafts. Photo ...
