NSK33275/33462DTapered Roller Bearing Cone and Double Cup Set 2-3/4 in Bore x 4-5/8 in OD Inch Series

Product Description

What this part is

An NSK 33275 tapered roller bearing cone with a 33462D double cup, inch series. Bore 2-3/4 in (69.85 mm), outside diameter 4-5/8 in (117.48 mm).

Decoding the designation

33275 — cone number, 2-3/4 in bore
33462 — cup number, 4-5/8 in outside diameter
D — double cup: one outer ring carrying two raceways

What these specs mean in practice

A double cup puts both outer raceways in a single ring, so one pressed-in cup serves two rows of rollers facing opposite directions. That arrangement takes thrust in both directions and carries a moment load, inside a single housing bore. Tapered rollers give a line contact, so radial and combined load capacity is high for the envelope.

Quantity and configuration

1 Set, comprising the 33275 cone and the 33462D double cup.

Fitting notes

The double cup presses into the housing bore and the cone presses onto the shaft journal, seated square against its shoulder. Setting is established after both races are in place by adjusting axial position to the specified end play or preload.

Interchange guidance

Cone and cup halves are matched by raceway angle and roller path, so the 33275 pairs with the 33462 raceway and the two numbers identify the set together. A single-width 33462 cup shares the raceway geometry but carries one row rather than two, making it a related part rather than an interchange.
