Decoding the designation

H924045 — Timken inch cone number. The 45 marks the cone within the H924000 series.

H924000 — the series that groups this cone with its mating cups, so the raceway angle and roller path are matched across the series.

What these specs mean in practice

Dynamic Load Rating: 557,000 N (125,000 lbf) at one million revolutions, the ISO basis. Dynamic Radial Rating C90: 144,000 N (32,500 lbf) at ninety million revolutions, the Timken basis. Dynamic Axial Rating Ca90: 167,000 N (37,500 lbf). Static Load Rating: 610,000 N (137,000 lbf). The two dynamic figures describe the same bearing on two different life bases, so quote them against the life standard the calculation uses.

K Factor: 0.87. K is the ratio of radial to thrust capacity and it comes straight from the cup angle. A value near 0.9 puts this cone in the steeper part of the inch range, giving it more thrust capacity than a shallow-angle series of the same bore.

G1 Factor: 246. G2 Factor: 32.2. Geometry Factor (Cg): 0.13. These feed Timken’s spin-torque and lubrication life adjustment calculations.

Mounting data

Effective Center Location: 0.27 in (6.9 mm) from the cone backface. Max Shaft Fillet Radius: 0.140 in (3.600 mm). Shaft Backing Shoulder Diameter – Frontface (da): 5.16 in (131.2 mm). Shaft Backing Shoulder Diameter – Backface (db): 5.47 in (139 mm). Cage Location relative to Backface (Aa): 0.23 in (5.8 mm). Cage Location relative to Frontface (Ab): 0.17 in (4.3 mm). The cone presses onto the shaft and seats against the shoulder; the fillet figure is the largest shaft corner radius the cone corner clears, and the cage-location figures give the axial envelope the cage sweeps.

Quantity and configuration

Cone only. Unit Quantity: 1 Pc. The matching single cup is the Timken H924010. The matching double cup for a TDO two-row arrangement is the Timken H924010D.

Cross-reference guidance

H924045 is an industry-standard inch tapered roller bearing cone number. SKF, FAG, NSK, NTN, Koyo, Bower/BCA, Tyson and National list this cone under the same designation. NTN prefixes its case-carburized inch range 4T-, giving 4T-H924045. Complete Timken assemblies built on this cone carry their own numbers, including H924045-90013, H924045-90014 and H924045-902A2.
