Engine Bearings Under Pressure - Engine Builder Magazine
4/12/2015· Engine Bearings Under Pressure. Today’s hi-flow, aftermarket, CNC-ported cylinder heads, high lift killer cams and induction system power adders (blowers, turbos and nitrous) are making more power than ever before, and really hammering the bottom end of the engine. If the bearings can’t take it, the engine won’t last.

Polymer Coatings, Engine Bearings, And The Science Behind Them
16/1/2018· The high load capacity (fatigue strength) of King polymer coatings is guaranteed by the balanced coination of a strong polymer matrix and the sum of its additives.” To ensure the additives have been distributed properly in the polymer mixture, King developed a proprietary technology to prevent sedimentation of the heavy particles.
Symptoms of Engine Bearing Failure - It Still Runs
Most neophyte car guys have heard of rod knock, if not heard it themselves. Rod knock -- a steady hammering that increases linearly with rpm -- happens when excess clearances causes by bearing wear cause the rod big-ends to hammer against the crankshaft at the top and bottom of the piston stroke. Rod knock is a sure indior of worn bearings.
Bearing Failure Analysis - Agkits
Engine Bearing Failure Analysis. Engine bearings depend on a film of oil to keep shaft and bearing surfaces separated (figure A). Bearings fail when the oil film breaks down or when the bearing is overloaded. The oil film is generated by shaft rotation (figure B). At rest, the shaft and bearing are in contact.
