Get Your Bearings
Have you ever heard the phrase “old wives’ tales”? My father used itall the time whenever something didn’t seem to make sense to him forthe moment. For instance, most everyone knows these: “Don’t cross youreyes or they’ll stay that way” and “feed a cold, starve a fever.” Like I said, they’re “old wives’ tales.” They
Selecting Cranks, Rods and Bearings For Your Next Build
Racing engines are made for one thing – speed. But speed is a wide target. It is in the sum of parts that are bolted together to make up the package that speed is delivered to your customer. Engine builders know that one of the biggest areas where races are won and lost is in

CSI: Engine Bearings: When Good Bearings Go Bad
Engine bearings have the dual function of reducing friction between a rotating part of the engine (the crankshaft) and the stationary part (the main caps and engine block) and supporting the crank. Because of the stresses caused by the explosions inside the internal combustion engine, the bearing material must be extremely strong, so a durable
Why Does The Appearance Vary On Engine Bearings?
For years you’ve seen engine bearings with a gray surface appearance due to the lead/tin overlay, but now with new bearing materials used in some applications you could find a variety of different looks. These differences will not only vary between engine models, but can also change depending on shaft diameter or journal size utilizing
Engine Bearings and Crankshafts, What makes them [not] tick?
The relationship between the crankshaft and main bearings is an integral one. Any metal-to-metal contact can have catastrophic results, and if the carnage was the result of improper finish or fitment, you’ll likely get to work on your relationship skills again. There are many analogies to explain how its parts relate to the engine as
PERA’s Core Corner: Back To the Basics On Engine Bearings
Have you ever heard the phrase “old wives’ tales?” My father used it all the time whenever something didn’t seem to make sense to him for the moment. For instance, most everyone knows this one: hang a horseshoe over your door for good luck. Now most of the world will do so with the open
Engine Bearings: Stock & Performance
The importance of the engine’s bearings can’t be over-emphasized. The bearings support the crankshaft and connecting rods, and in pushrod engines also the camshaft. The bearings provide a surface for the friction-reducing oil film that allows the parts to spin without rubbing metal against metal. It’s a tough job because of the high loads created
Crankshafts and Bearings – Keeping the Relationship Strong
Today’s engines typically have very tight tolerances everywhere and the crankshaft bearings are no exception. The truer the crank is in its alignment with the mainline and cylinder bore, the tighter the tolerances can be. Bearings and mainline bores must be very precise because during operation the crankshaft is not actually straight: it is elastic.

Ensuring Bearing Life: Crankshaft Bearings Are Always Replaced When Rebuilding An Engine
Crankshaft bearings are always replaced when rebuilding an engine because they’re a wear component. Heat, pressure, chemical attack, abrasion and loss of lubrication can all contribute to deterioration of the bearings. Consequently, when an engine is rebuilt new bearings are always installed. “Reading” the old bearings can reveal a great deal about conditions that may
