Timken 497-3 single-row tapered roller bearing cone — the inner ring with its tapered rollers and cage retained as one unit. Cone only. The matching cups are the Timken 493 and the Timken 492A. Design Units: Inch (Imperial). Series: 495 type, TS single row. Base Number: 497. Number Of Rows: 1. Rolling Elements: Tapered roller. Bearing Material: case-carburized alloy steel. Manufactured in the United States. GTIN: 053893047218.
Precision Class: Timken Class 3, from the trailing -3. Class 3 is a tighter bore and outside-diameter tolerance grade than the standard Class 4 / Class K used on general-purpose inch tapered bearings. 497 is the cone number; the cup carries its own number, so the assembly is written 497/493 or 497/492A according to which cup is fitted.
Class 3 narrows the tolerance band on the cone bore and raceway, giving more repeatable shaft position once the set is adjusted. Both cups accept the same 3.3750 in bore cone and give the same 1.1875 in assembly width, while the 493 is a 5.3750 in outside diameter and the 492A a 5.2500 in, so the housing bore sets the choice between them.
Bore: 3.3750 in / 85.725 mm. Cone Width: 1.1720 in / 29.769 mm. Cone Backface To Clear Radius: 0.14 in. Cone Frontface Backing Diameter: 3.54 in. Cage-Cone Frontface Clearance: 0.12 in. Cage-Cone Backface Clearance: 0.07 in. Effective Center Location: -0.03 in. Cage Type: pressed, one-piece. Cage Material: pressed steel. Dynamic Load Rating (C1): 34,700 lbf / 154.4 kN for the assembled single-row bearing. Static Load Rating (C0): 48,600 lbf / 216.2 kN for the assembled single-row bearing. Assembly envelope with the 493 cup: 3.3750 × 5.3750 × 1.1875 in. Assembly envelope with the 492A cup: 3.3750 × 5.2500 × 1.1875 in.
Unit Quantity: 1 Pc — one cone assembly comprising inner ring, rollers and cage. The outer race is a separate component.
497 is the industry cone number and carries across the inch tapered interchange unchanged. Assemblies: 497/493 and 497/492A. The 497A is a related cone in the same cup family, with its own raceway geometry, running against the 493 and 492A cups as 497A/493 and 497A/492A. Carton and search variants: 497-3, 497 3, 4973, 497*3, 497 #3, 497.
