Timken 49576 *3 inch tapered roller bearing cone, the inner ring carrying its tapered rollers and cage. Bore Diameter: 1.7500 in (44.450 mm). Overall Width: 1.2500 in (31.750 mm). Series: 49500. Base Number: 49576. Number Of Rows: 1. Rolling Elements: Tapered Roller. Bore Type: Straight. Bearing Material: Steel. Precision Class: Class 3. Item Weight: 1.30 kg (2.90 lb).
49576 — the cone base number in the Timken 49500 inch tapered series, fixing the bore, the roller path and the cup pairing.
*3 — precision Class 3, written interchangeably as *3, -3 or #3. Class 3 holds tighter bore and running tolerances than standard, giving lower running vibration and closer shaft location.
Dynamic Load Rating: 157,000 N (35,400 lbf) at 1 million revolutions. Static Load Rating: 155,000 N (35,000 lbf). Dynamic Radial Load Rating C90: 40,800 N (9,170 lbf). Dynamic Axial Rating Ca90: 28,000 N (6,290 lbf). K Factor: 1.46. Geometry Factor Cg: 0.0946. G1 Factor: 49.1. G2 Factor: 14.2. A K factor of 1.46 puts this cone in the steeper half of the inch range, so the thrust share it carries alongside a radial load is substantial, and the axial rating of 28,000 N reflects that.
Effective Center Location: -0.28 in (-7.1 mm), inside the cone backface. Max Shaft Fillet Radius: 0.030 in (0.8 mm) on the mating shaft. Shaft Backing Shoulder Diameter Frontface da: 2.13 in (54 mm). Shaft Backing Shoulder Diameter Backface db: 2.17 in (55 mm). Cage Location Relative To Backface Aa: 0.07 in (1.8 mm). Cage Location Relative To Frontface Ab: 0.09 in (2.3 mm).
Unit Quantity: 1 Pc. Cone only. The matching cups are the Timken 49520 and 49521, and the flanged 49520-B seats in a through-bored housing.
The 49576 cone number is also listed by SKF, FAG, NSK, NTN, Koyo, Fersa, BCA/Bower and PEER. Those numbers are the base cone; this unit is the Class 3 precision execution. MPN Variants: 49576, 49576-3, 49576 *3, 49576#3, 49576*3, 49576 3.
