Product Description

What this part is

A Timken L319249 single-row tapered roller bearing cone — the inner ring complete with its tapered rollers and cage. Bore 3-3/4 in.

Decoding the designation

L319249 is an ANSI/ABMA inch tapered roller number. The …249 ending marks the cone half of the set; the cup half carries the number L319210. The L prefix denotes the light inch section, a shallow raceway angle in a slim outer envelope.

What these specs mean in practice

A single-row tapered roller bearing takes radial load and thrust in one direction. The cone and its cup are lapped together as a set at manufacture, so the roller path and raceway angle belong to the set number rather than to either half.

Published specifications

Bearing type: tapered roller bearing cone (inner ring, rollers and cage)Design units: inchBore: 3-3/4 in (95.25 mm)Number of rows: 1Bore type: straightClosure: openMating cup: L319210

Quantity and configuration

Cone only. The matching cup is the Timken L319210. Sold as 1 Pc.

Fitting notes

The cone is a press fit on the shaft journal against a square shoulder; the cup seats separately in the housing bore, and endplay or preload is set at assembly by shim or adjusting nut.

Interchange guidance

L319249 is a standardised inch cone section carried under the same base number by Timken, Koyo, NTN and FAG. A cone with a different base number sharing the same bore is a related size, not an interchange.
