Timken496Single-Row Imperial Tapered Roller Bearing Cone – 3-3/16 in Bore, 1.172 in Width, K Factor 1.31

Product Description

What this part is: Timken 496 is a single-row imperial tapered roller bearing cone — the inner ring, tapered rollers and cage as one assembly. Bearing Type: Tapered roller bearing cone. Bore: 3-3/16 in (80.963 mm). Inner Ring Width: 1.1720 in (29.769 mm). K Factor: 1.31. Dynamic Radial Load Rating (C1): 34,700 lbf (154,000 N). Dynamic Radial Load Rating (C90): 9,000 lbf (40,000 N). Dynamic Axial Rating (Ca90): 6,850 lbf (30,500 N). Static Radial Load Rating (C0): 48,600 lbf (216,000 N). Item Weight: 8.72 lb (3.953 kg). Number Of Rows: 1. Precision Class: Not specified. Decoding the designation: 496 — the 490 imperial cone series at a 3-3/16 in bore, running against 492A and 493 cups. Within the series the bore steps with the number: the 495A is 3 in and the 496 is 3-3/16 in on the same 1.1720 in ring width, so a 496 drops into the same cup on a larger shaft. What these specs mean in practice: K Factor: 1.31 is the ratio of radial to thrust capability, and at that value the 496 carries substantial thrust alongside its radial load in one direction. Dynamic Radial Load Rating (C1): 34,700 lbf against Static Radial Load Rating (C0): 48,600 lbf leaves headroom for shock and standing load. Effective Center Location: −0.03 in, which sits just inside the cone backface and is the point to use when setting bearing spacing on the shaft. Mounting data: Shaft Backing Shoulder Diameter, frontface (da): 3.5 in (89 mm). Shaft Backing Shoulder Diameter, backface (db): 3.74 in (95 mm). Max Shaft Fillet Radius: 0.140 in (3.600 mm) — the largest fillet on the shaft that the cone corner will clear. Cage Location relative to backface (Aa): 0.07 in. Cage Location relative to frontface (Ab): 0.12 in. G1 Factor: 104.6. G2 Factor: 29.3. Geometry Factor (Cg): 0.125. Quantity and configuration: Unit Quantity: 1 Pc. Cone only — inner ring, rollers and cage as a single assembly. The matching cups are the Timken 493 and 492A. Interchange guidance: Part Number: 496. Searchable variants: 496 cone, Timken 496, 496 taper cone. The 495A is the 3 in bore cone in the same series and against the same cups.
