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 ...

Heavy press fits should be avoided. Accuracy of mounting surfaces should be equal to accuracy of mating bearing surface. Misalignment for low torque and running accuracy should not exceed 1/4°.

At light loads an externally pressurized sleeve bearing tends to be stiffest, followed by rolling-element bearings and self-acting sleeve bearings. As loads increase, the rolling-element bearing ...

I don’t know why, but in recent years I’ve seen a rash of bearings with cracked inner races. Sometimes the damage was on relatively new machines with very few hours on them. Symptoms related to a ...
