H Series Conrod Bearing Set .010"
Suit BB Chev 366, 396, 402, 427, 454, 502 & 348-409 With Dowel Hole
H-Series Bearings
 
These bearings are identified by a letter H in the part number suffix. Part numbering is based on the same core number as the standard passenger car parts for the same application. These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines.
 
H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001" extra clearance are available for standard size shafts and carry the suffix HX" (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 degrees upper half grooving and with full 360 degrees grooving (H = 180 degrees, HG 360 degrees). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface. See accompanying contact pattern diagrams. If you aren't sure which type of performance bearing to start with, the H series bearing will be your best choice.
 
Please note: Some "H" series bearings will no longer be available with enlarged chamfers. Instead, the bearings will be narrowed in place of the enlarged chamfer to provide greater crankshaft fillet clearance. The new narrowed bearings will be available with a "HN" suffix and will be replacing the standard "H" suffix part number.

TriArmour Conrod Bearing Set .001"
Suit BB Chev366, 396, 402, 427, 454, 502 & 348-409
TriArmour Series Bearings
 
The exclusive Clevite TriArmor engine bearings feature the industry's only moly/graphite treatment. This sophisticated blend, in a low friction PTFe polymer base, offers extraordinary protection and lubricity. enhanced wear characteristics increase bearing life in race engines and high performance street engines.
 
Now, high performance engine builders can enjoy the strength and durability of the legendary Clevite TriMetal bearing construction coupled with the latest in coating technology - right out of the box.
 
The line of Clevite TriArmor rod and main bearings include popular Ford, GM and Chrysler models as well as popular Sport Compact applications.
 
Exclusive Moly/Graphite Treatment
 
For years, engine builders have experimented with coating engine bearings for race engines and high performance street engines, with varying degrees of success. Now, Mahle Clevite engineers, after extensive research and development, have devised TriArmor, a proprietary blend of molybdenum disulfide (MoS2) and graphite all carried in an inert polymer substrate.
 
Central to this breakthrough is the exclusive use of graphite and unique application and low temperature cure processes. These processes provide extremely uniform thickness coupled with unparalleled adhesion, all while protecting the metallurgical integrity of the bearing during the coating procedure.
 
The result? A thin protective coating that offers:
 
Reduced friction and drag, resulting in increased horsepower
Protection during start-up
embedability to resist damage from debris
Ability to withstand extreme temperatures and pressures
Conformability for distressed or imperfect surfaces
extraordinary strength and durability
TriArmor Features &Benefits
 
In developing TriArmor materials and processing, MAHLE Clevite engineers relied on the science of Tribology, the study of design, friction, wear, and lubrication characteristics of interacting surfaces. With our existing body of knowledge based on decades of producing bearings for street and track, this model enabled us to produce the most advanced and efficient coating material possible. The PTFE carrier material gives good low load start-up protection. The moly serves as a high pressure, high load dry film anti-wear agent. Graphite provides additional protection across a broad range of temperatures, especially when oil flow is marginal and is especially slippery with an oil film.
 
Exclusive Clevite TriArmor Features:
 
Moly/graphite compound
Coverage for Ford, GM and Chrysler as well as popular Sport Compact Applications
Parting lines not coated
Legendary Clevite quality
