L — Timken’s inch prefix for a low-section tapered roller series, giving a shallow cross-section for a given bore.
305649 — the cone number in the L305600 series. Base Number: L305649. Series: L305600.
*3 — Precision Class: Class 3. A tighter running tolerance than standard, giving lower running vibration and closer shaft location. The same marking appears as L305649-3, L-305649 *3 and L305649#3.
K Factor: 1.64. The K factor fixes the ratio of radial to thrust capacity; at 1.64 this raceway angle leans toward radial capacity while still taking significant thrust. Dynamic Axial Rating (Ca90): 9,590 N. Dynamic Radial Rating at 90 million revolutions (C90): 15,800 N. G1 Factor: 38.8. G2 Factor: 29.8. Geometry Factor (Cg): 0.0841, the constant Timken uses in its lubrication life adjustment factor.
Effective Center Location: –0.1 in (–2.5 mm), measured inside the cone back face. Maximum Shaft Fillet Radius: 0.060 in (1.5 mm) — the largest shaft corner radius the cone back face clears. Shaft Backing Shoulder Diameter, Frontface (da): 2.20 in (56 mm). Shaft Backing Shoulder Diameter, Backface (db): 2.28 in (58 mm). Cage Location relative to back face (Aa): 0 in. Cage Location relative to front face (Ab): 0.10 in.
Unit Quantity: 1 Pc. Cone only — inner ring, roller set and cage. The matching cups are the Timken L305610 and L305611.
L305649 is the industry designation for this cone and is carried by SKF, FAG as K-L305649, NSK, NTN as 4T-L305649, Koyo, Fersa and BCA/Bower.
