Timken3576Tapered Roller Bearing Cone – 1-5/8 in Bore, 1.2160 in Width, Case-Hardened Steel

Product Description

What this part is: Timken 3576 inch tapered roller bearing cone. Cone only. A cone is the inner ring with its roller and cage assembly. The matching cup is the Timken 3525. Part Number: 3576. Base Number: 3576. Series: 3500. Bearing Type: Tapered roller bearing cone. Design Units: Imperial. Material: Case-hardened steel. Key dimensions: Bore / Shaft Size: 1-5/8 in (41.275 mm). Overall Width: 1.2160 in (30.886 mm). Total Width: 1.2160 in (30.886 mm). Item weight: 1.400 lb (0.6 kg). Load ratings: Dynamic Radial Load Rating (C1, 1M revs): 25500 lbf (113000 N). Dynamic Radial Load Rating (C90, 90M revs): 6610 lbf (29400 N). Dynamic Axial Rating (Ca90, 90M revs): 3460 lbf (15400 N). Static Radial Load Rating (C0): 30100 lbf (134000 N). Decoding the designation: 3576 — the cone number in the Timken 3500 inch series, paired at the factory with the 3525 cup. Mounting data: Effective Center Location: −0.4 in (−10.2 mm), inside the cone backface. Maximum Shaft Fillet Radius: 0.030 in (0.8 mm). Shaft Backing Shoulder Diameter, Frontface (da): 1.89 in (48 mm). Shaft Backing Shoulder Diameter, Backface (db): 1.93 in (49 mm). Cage Location relative to Backface (Aa): 0.07 in (1.8 mm). Cage Location relative to Frontface (Ab): 0.05 in (1.3 mm). K Factor: 1.91. G1 Factor: 39.5. G2 Factor: 10.5. Geometry Factor (Cg): 0.0808. What these specs mean in practice: The K factor of 1.91 is the ratio of radial to thrust capacity for this cone. A high K means the roller path is shallow, so the cone puts most of its capacity into radial load and comparatively little into thrust — which is why the 25500 lbf radial rating sits so far above the 3460 lbf axial figure. The effective centre sits 0.4 in inside the cone backface, so the load line and the physical face are not in the same plane. That offset is what a bearing spacing calculation works from when two cones are set opposed on one shaft. The da and db shoulder diameters and the 0.030 in maximum shaft fillet radius define the shaft seat the cone presses onto, so an existing shaft can be checked from published numbers.
