KING ENGINE BEARINGSPERFORMANCE-ENGINEERED FOR A FIRST-PLACE FINISH

King Engine Bearings have the closest wall

tolerances in the industry, with all shells matched to .0001". That’s what we call “hitting the bull’s eye!” Ourengine bearings are specifically engineered to withstand the highest loads and RPMs for today’s top competition engines.

Our three performance brands are all about power. From huge power that lasts for seconds, to high power that lasts for hours, King has a race bearing that best suits your needs.

Do your bearings look like this?

What causes this type of bearing failure?

h Engine loads that exceed the bearing’s fatigue point.

h Temperatures that exceed the bearing’s temperature threshold.

If you’re encountering this type of wear on your bearings, your engine could be a candidate for King GP engine bearings.

We’re currently field-testing this new product line, intended for very high-performance vehicles that wear down conventional bearings.King GP bearings’ proprietary overlay withstands almost twice the load of other performance bearings (18,000 psi vs 10,000 psi).The temperature threshold is 50% greater than others(540ºF vs 350ºF).

18,000 psi and 540°F gives you so many possibilities, and lets you try to push performance in ways you couldn’t dream of before. If you’re all about power, GP is designed to handle every challenge so you can let your imagination run wild.

If you’d like to participate in our field testing, please contact King Engine Bearings and tell us about your situation.

HP BEarinGs at-a-glance

PROBLEM #1:Your current tri-metal bearing’s Babbitt overlay extrudes over the sides, migrates to one end, or gets physically removed by the crankshaft. The intermediate layer is exposed, damaging the crank journal and requiring expensive grinding or replacement.

CAUSES:• Engine load and/or

temperature exceed the limits of your bearing.

• Excessive engine load overcomes the hydrodynamic lubrication principle, allowing metal-to-metal contact between crank journal and bearing.

PROBLEM:Your current OE or performance bearing is flaking or “chunking out” (tri-metal/bi-metal fatigue failure).

CAUSE:• Engine load exceeds your

bearing’s fatigue point.

SOLUTION:King XP bearings

✓ The .0005” high performance overlay and tri-metal, copper lead construction offer 15% – 30% greater load capacity than conventional OE or bi-metal bearings.

✓ XP bearings feature SecureBond, King’s enhancedadhesion process.

✓ A special surface preparation and heat treatment ensures superior adhesion between nickel dam and intermediate layer.

✓ Temperature threshold is 350ºF. ✓ Load capacity is 10,000 psi.

Applications: high-load, long duration racing such as circle track, off-road, off-shore, etc. using steel crankshafts.

Ron Shaver and others are currently advance-testing King GP bearings in sprint and circle track engines.

PROBLEM #2:Contaminants enter the oil stream, scratching and damaging the crankshaft journals.

CAUSE:• Failure to eliminate residual

machining particles from last rebuild.

SOLUTION:King HP bearings

✓ The .015” thick top layer of the bi-metal bearing can be squeezed and worn up to .010” (vs tri-metal’s .0005”) without damaging the crank journals.

✓ 40 Vickers hardness withstands momentary high loads better than softer Babbitt’s Vickers hardness of 15-20.

✓ The thick top layer provides better macro-particle (>.00025”) embedability vs tri-metal Babbitt (.015” thickness vs .0005”).

✓ Temperature threshold is almost 30% higher than tri-metal (450ºF vs 350ºF).

Applications: high-load, short duration racing such as dragracing, tractor pulls, monster trucks, etc. Also for medium-load, long duration racing such as circle track engines using nodular cast iron crankshafts.

Mastering the Part #Introducing ourSimplied Numbering SystemOur new system retains the “core number” from the OEM replacement bearing and changes the su�x to re�ect material and features.

Additionally, we’re now narrowing our rod bearings instead of chamfering. This is a more highly engineered solution that is also cleaner and more professional looking. All eight cylinder rod bearings will feature the N (narrowed) design.

The pre­x identi­es the component (Connecting Rod Bearing = CR,Main Bearing = MB)

The ­rst number indicates how many pairs are in the set (8 pairs)

The next two letters indicate construction:HP = Bi-metal orXP = Tri-metal

N = narrowedD = dowel
