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.
King bearings use just two layers, a high strength steel backing plus a bonded layer of Alecular bearing material .012 - .015 thick.
Alecular material is used exclusively by King. It 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.Very popular among the Blown Alcohol and Nitro teams.
Note:
-
Main Bearing part numbers with the Letter N in them are
Narrowed (for crank radius clearance)
- X = Extra Oil Clearance
- .001 .010 .020 are Undersize
(For Cranks that have been turned down)
