Timken 25572-25520 Tapered Roller Bearing Set

Timken 25572-25520 is a matched single-row tapered roller bearing set, comprising cone 25572 and cup 25520, designed to support combined radial and axial loads in rotating equipment. Its precision-ground raceways and separable cone-and-cup design provide accurate shaft positioning and high load capacity, with a 1.5000 in bore, 3.2650 in outside diameter, and an overall width of 0.9375 in (cone width 1.0000 in, cup width 0.7500 in). The assembly carries dynamic radial load ratings of C1 20,300 lbf and C90 5,270 lbf, static radial load rating C0 24,900 lbf, and dynamic thrust rating Ca90 of 3,020 lbf, and weighs 1.4 lb. It is commonly used in industrial gearboxes, conveyor drives, axle assemblies, machine tools, agricultural equipment, mining machinery, and material handling systems requiring precise alignment and reliable performance; common replacements include SKF 25572/25520 and NTN 25572/25520.
