Decoding the designation:

3761 — the cone base number in the Timken 3700 inch tapered roller series. The number carries no suffix, so the part is a standard-tolerance cone and the Precision Class reads as Not specified.

What these specs mean in practice:

A tapered roller bearing separates into two parts, the cone assembly that runs on the shaft and the cup that seats in the housing. The taper on the raceway lets one bearing take radial load and thrust in a single direction at the same time, and a pair mounted in opposition sets the axial float of the shaft. Case-carburized alloy steel gives a hard running surface over a tough core, which is what lets a tapered roller bearing take shock loading.

Quantity and configuration:

Cone only, comprising the inner ring, the roller set and the cage as one non-separable assembly. Unit Quantity: 1 Pc.

Interchange guidance:

3761 is a plain inch tapered roller cone number and the industry carries it under the same digits across the major makers. Cross-references: SKF 3761, FAG K-3761, NSK 3761, NTN 4T-3761, Koyo 3761, Fersa 3761, BCA 3761, PEER 3761.
