Decoding the designation

H — Timken heavy-section inch series prefix, carried by both halves of the pairing.

432649 — the cone number, fixing the 5.9995 in bore and the raceway angle.

432610 — the cup number, fixing the 10.6250 in outside diameter and the matching raceway.

What these specs mean in practice

Dynamic Load Rating: 775,000 N (174,000 lbf) at 1 million revolutions. Static Load Rating: 1,180,000 N (265,000 lbf). Dynamic Radial Rating C90: 201,000 N (45,200 lbf). Dynamic Axial Rating Ca90: 129,000 N (28,900 lbf). K Factor: 1.56. e Factor: 0.37. Y Factor: 1.6. G1 Factor: 598. G2 Factor: 74.8. Geometry Factor (Cg): 0.114.

A K factor of 1.56 puts this pairing at a steeper raceway angle than a general-purpose inch taper, so it takes a larger share of its capacity as thrust. Mounting a second bearing facing the other way locates the shaft in both directions and lets the pair be set to a chosen end play or preload.
