Timken 466S-3 inch tapered roller bearing cone, the inner ring with its roller and cage assembly. Cone Part Number: 466-S. Series: 455. Base Number: 466S. Design Units: Imperial. Rolling Elements: Tapered Roller. Number Of Rows: 1. Bore Type: Straight. Bearing Material: Case-Carburized Steel. The matching cups are the Timken 453A and 453AS.
466 — the cone number in the 455 series, fixing a 2.1875 in bore.
S — the wide-inner-ring execution of the 466, giving a 1.1542 in inner ring width and a longer roller path than the plain 466.
-3 — Precision Class 3, also written *3 and #3. Tighter running tolerance, lower running vibration and closer shaft location than standard class.
Bore Diameter: 2.1875 in (55.563 mm). Overall Width: 1.1542 in (29.317 mm). Precision Class: Class 3. Item Weight: 2.91 kg (6.42 lb).
Dynamic Load Rating: 161,000 N at one million revolutions. Static Load Rating: 166,000 N. Dynamic Radial Rating at 90 million revolutions: 41,700 N. Dynamic Axial Rating at 90 million revolutions: 23,900 N.
K Factor: 1.74. A K factor of 1.74 sets the ratio of radial to thrust capacity through the roller taper, giving this cone a radial bias with substantial single-direction thrust reserve.
G1 Factor: 58.6. G2 Factor: 17.1. Geometry Factor (Cg): 0.0946.
Effective Center Location: -0.28 in, inside the cone backface. Shaft Backing Shoulder Diameter, frontface: 2.44 in. Shaft Backing Shoulder Diameter, backface: 2.60 in.
Maximum Shaft Fillet Radius cleared by the bearing corner: 0.09 in. Cage Location relative to backface: 0.07 in. Cage Location relative to frontface: 0.08 in.
Unit Quantity: 1 Pc. Cone only. The matching cup is the Timken 453A.
466S is an industry-standard inch taper cone number, so the same base designation carries across makers: SKF 466S, FAG K-466-S, NSK 466S, NTN 4T-466S, Koyo 466S, Fersa 466S, BCA/Bower 466S, PEER 466S. Those are standard-precision cones; this Timken 466S-3 is the Class 3 execution.
Searchable designation variants: 466S-3, 466S*3, 466S#3, 466-S 3, 466 S 3, 466S, 466-S, Class 3 precision.
