A complete two-row (2TS) matched tapered roller bearing assembly built from LM603049 cone and LM603011 cup members, supplied under the assembly number LM603049-90033. One pre-configured assembly of six individual bearing pieces, factory-selected so that its members work together to produce a specific internal setting. Unit Quantity: 1 assembly.
LM603049 — the cone, the inner ring plus roller and cage assembly.
LM603011 — the cup, the outer race. LM603049/LM603011 together is the standard single-row set designation.
-90033 — assembly number identifying a specific pre-configured matched assembly rather than a loose component.
XF — special-feature cone, a member that differs from the base LM603049.
EX — special-feature cup, a member that differs from the base LM603011.
Bearing Type: Tapered roller bearing, two-row (2TS) matched assembly, cup and cone. Rolling Elements: Tapered rollers. Number Of Rows: 2. Material: Steel. Contents of the assembly: 2 x LM603049 standard cones, 2 x LM603011 standard cups, 1 x LM603049XF special-feature cone, 1 x LM603011EX special-feature cup, six pieces in total.
Single-row member dimensions: Bore d: 1.7812 in (45.242 mm). Cup outside diameter D: 3.0625 in (77.788 mm). Single-row assembly width T: 0.7812 in (19.842 mm). Cup width C: 0.5937 in. Cone width B: 0.7812 in.
A plain LM603049 cone or a plain LM603049/LM603011 single-row set is a different item. The assembly number LM603049-90033 is a specific build. MPN Variants: LM603049-90033, LM603049 90033, LM60304990033, LM603049/LM603011, LM603049/11, LM603049, LM603011, LM603049XF, LM603011EX.
