King bearings??

[capri71]

anyone heard of these bearings?

"These bearings are manufactured by KING BEARINGS. King is one of the top manufacturers for the US Space Program, and they use the same quality assurence on their engine bearings. King Bearings are not only of outstanding quality, but they are very unique in design. Here is where quality, design, and value all come together. These are simply the best bearings on the market. The benefits of using these bearings are:

Tri-Metal vs. Bi-Metal Bearings

Traditional rod and main bearing construction is based upon a three layer configuration composed of a steel backing, a copper-lead layer and a very thin overlay of babbitt material only .0005" - .0008" thick.

These bearing uses just two layers, a high strength steel backing plus a bonded layer of "Alecular" bearing material .012" - .015" thick.

Alecular material is an alloy of aluminum, tin, copper and several other elements. Because it is an alloy, it maintains its properties throughout its entire depth, delivering consistent and reliable performance.

Particle Embedability

More than half of engine bearing failures are caused by metallic particles which scratch crank journals and tear or weaken thin babbitt overlays such as in the tri-metal bearing.

Since Alecular bearing layer is much thicker than the babbitt overlay (.015" vs. .0008"), it provides eighteen (18) times more embedability than a tri-metal bearing to catch and hold particles so they don’t scratch the crank journals. This is especially true for particles over .0004" in diameter which cause most of the damage.

Conformability

The much thicker layer of Alecular bearing material (.015" vs. .0008") allows the bearing to conform to problems such as metal to metal contact when there is mis-alignment present or the connecting rods stretch. Greater conformability means fewer bearing failures.

Temperature Resistance

The Alecular material’s melting/fatigue point is over 11000 F, almost three times that of the thin babbitt overlay in a tri-metal bearing (400OF). This means added protection against localized overheating due to mis-alignment, detonation, overloading, loss of coolant, etc.

You simply CAN'T buy a better quality Bearing Set for any production application, AT ANY PRICE…"

any good?? http://www.ebay.co.uk/itm/300701210783?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

Got some king bearings in my 2.9 , so I hope they're as good as they say !

they seem to know there onions, there's alot of people coating bearings now, but this only aids with start conditions, if the bearing have metal to metal contact whilst running then there is only one way they will go!

  Ade's engine originally was going to have ks bearings but he was happier with clevite 77 as they have a good rep,never had any dealings with king but its the tolerance and oil thats more important,measure every bearing installed no matter who made them! it marks them slightly with a bore gauge but nothing that would cause a problem.

 there has been some massive improvements with bearings but it has been diesel engines which have pushed this forward

fingers crossed Matt

Cheers Graham, interesting that clattering oil burner are blazing a trail it kind of makes sense with all the compression, low rpm and long strokes. its a recipe for laboured bearing i imagine.

On a forum some yank was saying people tuning duratecs are using "SHO" bearing? do they mean the volvo/yamaha v8 thing?? any ideas what thats about?

[turboshed]

It was the yamaha v6 engine.maybe v8 aswell not sure
super high output

[capri71]

ha! found SHO owners use Duratec bearings! Its because the SHO has the same rods and the Duratec bearings are cheaper to buy. I saw a post on a contour forum saying SHO bearings fail in duratecs so altogether, more internet crap… but we have to check it or you chuck out the baby with the bath water

Most production duratecs use bearings made by speedpro as standard.

Personally, I use clevite 77 bearings. King bearings seem to be good also.

I am with Turboshed as he says: but its the tolerance and oil thats more important, measure every bearing installed no matter who made them!

Measure and measure again. And not with plastic but with a micrometer.



 

[capri71]

must admit, i would of just fired them in but yeah, i'll check them with the micrometer

That deal where you get the King mains and big ends for £55 plus £14 priority mail international is well worth it. I looked on burtons… for a laugh like

I've just got a bunch from the states,I can't see that they'll be crap,as they boast about their brand on their website

My mate was telling me that if you have an account with eurocarparts, you get HUGE discount…I'm gonna find out if its true before i buy anything else for the moment. I know they do an Duratec v6 clutch kit for £105 anyway so could be interesting with big discount too ...and they are 5 minutes walk from my house.

hi
can you tell which duractec engine is it the 3.0 liter one is it the rod bearing that your talking about? i have a few sho engine who need some rod bearing and also the main too can you give me some more info and also the part number if you can thank you
