| High Performance; Set; H Series (Tri-Metal) |
H-Series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. 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. If you aren't sure which type of performance bearing to start with, the H-Series bearing will be your best choice.
Clevite® TriMetal™ engine bearings have been the industry standard since the first patent on the cast, copper, lead composition decades ago. These points are just a few of the advantages Clevite's TriMetal™ engine bearings:- Seizure Resistance - Clevite TriMetal™ bearings have as much as 40% better seizure resistance than competitors' engine bearings.
- Load Capacity - Clevite TriMetal™ bearings can withstand over 60% higher loads for extended periods compared to competitor bearings.
- Embedability & Conformability - The overlay on a TriMetal™ bearing offers a superior surface for forgiveness, offering additional protection that can be extremely beneficial in an engine that is poorly maintained.
- Durability - Clevite TriMetal™ bearings not only exceed light vehicle OE durability requirements of 150,000 miles, they also exceed heavy vehicle OE durability requirements of 300,000 miles.
- Even all tri-metal engine bearings are not the same. If you want the highest quality, strongest, and original TriMetal™ bearings, ask for Clevite Engine Bearings.
The letters at the end of each part number indicate a specific feature of the part.
Example:
Part #CB1234HXNK: H = High Performance, X = .001" more oil clearance than standard, N = Narrowed for greater crankshaft fillet clearance, K = TriArmor™ coating applied to the bearing surface.
| Letters & Their Meanings | A
Steel backed lead free aluminum silicon alloy bearings without overlay. Standard replacement material. | M
Steel backed bearings with a Micro-Babbitt lining (a very thin layer of lining which reduces the microscopic deflections that occur to a bearing when loaded and thus increases fatigue life). Solely intended for extreme high-horsepower applications. | AL
Solid cast aluminum alloy bearings (material designation AL-1) or steel backed bearings with an aluminum alloy lining material designation AL-3, AL-4, AL-5, AL-6). Standard replacement material. | N
Narrowed for greater crankshaft fillet clearance. | B
Steel backed bearings with a conventional babbit lining. | P
Steel backed bearings with an intermediate layer of copper-lead alloy and an electroplated lead-tin-copper overlay. Standard replacement material. | C
Steel backed bearings with a copper-lead lining. | R
Indicates that the bearing can be resized to standard. When following a camshaft bearing, indicates that it has extra bore stock in the inside diameter. | D
Bearing has dowel hole. | S
Indicates a set number designation. | G
Steel backed bearings with a matrix of copper and an infiltrant of lead-tin babbitt. Precision undersizes are not resizable. | V
High performance bearing with a lead-indium overlay (on main sets this indicates partial groove). Solely intended for extreme high-horsepower applications. | H
High performance bearing (on main sets this indicates partial groove). Perform the same as "A" and "P" bearings, but have the ability to carry more load. | VG
High performance bearing with a lead-indium overlay and a full annular groove. Solely intended for extreme high-horsepower applications. | HG
High performance full annular grooved bearing. Perform the same as "A" and "P" bearings, but have the ability to carry more load. | X
Bearing has .001” more oil clearance than standard. | HT
High performance with indentless locating lug. “Full Bore” design. Perform the same as "A" and "P" bearings, but have the ability to carry more load. | XX
Bearing has .002” more oil clearance than standard. | K
TriArmor™ coating applied to the bearing surface, which offers extraordinary protection and lubricity. Enhanced wear characteristics increase bearing life in race engines and high performance street Engines. | W
Indicates a part that is a thrust washer (may also be designated upper or lower). |
