Decoding the designation

M716610 — the cup base number in the Timken M716600 inch tapered roller series.

B — flanged. The outer ring carries an integral flange on the backface, so the cup locates axially against the face of the housing instead of against an internal shoulder. The carton is marked M-716610-B.

–3 — Precision Class 3. Tighter tolerance than standard, giving lower running vibration and closer seating in the housing bore. Cartons write the same code as M716610B *3 and M716610B #3.

What these specs mean in practice

The cup is the outer race of a tapered roller bearing and presses into the housing bore, carrying the tapered raceway the rollers run against. The 5.117 in outside diameter is the housing fit and the 0.945 in width is the axial space the outer ring occupies. The integral flange turns a through-bored housing into a located seat, so the machining behind the bearing can be a plain bore rather than a counterbored shoulder. Case-carburized alloy steel gives a hard raceway over a tough core, which is what lets the outer ring pass shock loading into the housing.

Quantity and configuration

Flanged cup only, a single outer race with its integral locating flange. Unit Quantity: 1 Pc.
