Product Description

What this part is

Timken 59200-3 tapered roller bearing cone. Bore 2.0000 in (50.80 mm). Cone width 1.4375 in. Series: 59000. Precision Class: Class 3. Stamped steel cage, case-carburized steel. Design units: imperial. Cone only. Country of origin: United States.

Decoding the designation

59200: inch tapered roller bearing cone, 59000 series, 2 in bore. The trailing 3, written -3 or *3, is Precision Class 3 — a tighter tolerance than standard, giving lower running vibration and closer shaft location.

Mounting dimensions

Cone frontface backing diameter: 2.4 in. Cone backface to-clear radius: 0.14 in. Effective centre location: −0.38 in. Cage-to-cone frontface clearance: 0.09 in; backface clearance: 0.11 in.

What these specs mean in practice

A cone carries the inner raceway, the roller set and the cage as one assembly, and runs against a matching cup. Class 3 tolerances hold bore and width to a tighter band than the standard class, which keeps shaft location and setting repeatable when a bearing is replaced. Case-carburized steel gives a hard raceway over a tough core, so the part takes shock loading well.

Quantity and configuration

Cone only. Unit quantity: 1 Pc.

Fitting notes

The cone is pressed on to a 2.0000 in shaft seat, working to the effective centre location above for spacing. Setting is by axial adjustment against the opposed bearing.
