An imperial single-row tapered roller bearing cone — the inner ring with its tapered rollers and cage. Cone only. Matching cup: 3720, a separate part number. Unit Quantity: 1 Pc.
BR — SKF’s designation for its inch-series tapered roller bearing range.
3782 — the standard imperial cone number used across the industry. Its matching cup is 3720, so a complete single-row bearing is a 3782 cone plus a 3720 cup. BR3782 and 3782 are the same part under two naming conventions.
Bore Diameter: 1.7500 in (44.450 mm). Overall Width: 1.1930 in (30.302 mm). Item Weight: 4.45 lb (2.02 kg). Series: 3700 imperial tapered roller. Dynamic Load Rating (C1, 3782/3720 assembly): 122,000 N (27,500 lbf). Static Load Rating (C0, 3782/3720 assembly): 153,000 N (34,300 lbf).

Dynamic axial rating Ca90: 4,120 lbf (18,300 N). K factor: 1.73. e: 0.34. Y: 1.77. Geometry factor Cg: 0.0903. Effective load centre: −0.32 in (−8.1 mm), inside the cone backface. Maximum shaft fillet radius cleared: 0.14 in (3.600 mm). Shaft backing shoulder diameter, frontface (da): 2.05 in (52 mm). Shaft backing shoulder diameter, backface (db): 2.28 in (58 mm).
Cross-references: Timken 3782, Koyo 3782, NTN 4T-3782, Bower/BCA 3782 and Federal-Mogul 3782. Each takes the 3720 cup. The 3767 is a related size: it uses the same roller set and the same 3720 cup, with a 2.0625 in bore instead of 1.7500 in.
