Decoding the designation:

42350 — a cone number in Timken’s inch 42000 tapered roller series, fixing the 3.5000 in bore and the 1.1406 in inner ring width.

No precision suffix is present on this part. Precision Class: Not specified.

What these specs mean in practice:

K Factor: 1.19. A K factor near 1.2 is a steep taper: the raceway angle puts a large share of the capacity into thrust, so the bearing suits a position carrying heavy combined radial and axial load.

Dynamic Load Rating: 193,000 N (C1, at 1 million revolutions, ISO method). Dynamic Radial Load Rating at 90 million revolutions (C90): 50,100 N. Dynamic Axial Rating at 90 million revolutions (Ca90): 42,200 N — 84 per cent of the radial figure. Static Load Rating: 241,000 N.

G1 Factor: 129.7. G2 Factor: 37.2. Geometry Factor (Cg): 0.139, the geometry constant for the lubrication life adjustment factor a3l.

Mounting data:

Maximum Shaft Fillet Radius: 0.120 in (3 mm) — the largest fillet the shaft shoulder may carry and still be cleared by the cone corner. Shaft Backing Shoulder Diameter, frontface (da): 3.86 in (98 mm). Shaft Backing Shoulder Diameter, backface (db): 4.09 in (104 mm). Effective Centre Location: 0.12 in (3 mm), measured outside the cone backface. Cage Location relative to backface (Aa): 0.10 in. Cage Location relative to frontface (Ab): 0.14 in.
