Part Number Identification
Part Number Identification
A
Steel backed lead free aluminum silicon alloy bearings without overlay.

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). Precision undersize bearings are not resizable. AL-1 semi bearings are resizable to standard size.

AP
See definitions for "A" and "P" suffixes.

B
Steel backed bearings with a conventional babbit lining. Precision undersizes are not resizable. B-60 bearings are resizable to standard size (material designation B-1).

C
Steel backed bearings with a copper-lead lining. Precision undersizes are not resizable. C-60 bearings> are resizable to a standard size (material designation C-1).

D
Bearing has dowel hole.

G
Steel backed bearings with a matrix of copper and an infiltrant of lead-tin babbitt. Precision undersizes are not resizable. G-60 bearings are resizable to standard size (material designation C-1).

H
High performance bearing (on main sets this indicates partial groove).

HG
High performance full annular grooved bearing.

HT
High performance with indentless locating lug. “Full Bore" design.
K
High performance bearing with proprietary TriArmor™ coating applied to the bearing surface.

M
Steel backed bearings with a Micro-Babbitt lining. Precision undersizes are not resizable (material designation B-2).

N
High performance bearing narrowed for greater crankshaft fillet clearance.

P
Steel backed bearings with an intermediate layer of copper-lead alloy and an electroplated lead-tincopper overlay. Precision undersizes are not resizable (material designation TM-1, TM-, TM-112).

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. All other camshaft bearings are precision type (material designation B-1, C-1, AL-3).

S
Indicates a set number designation.

V
High performance bearing with a lead-indium overlay (on main sets this indicates partial groove).

VG
High performance bearing with a lead-indium overlay and a full annular groove.

X
Bearing has .001" more oil clearance than standard.

XX
Bearing has .002" more oil clearance than standard.

W
Indicates a part that is a thrust washer (may also be designated upper or lower).
