The Timken Company T151W Tapered Roller Thrust Bearing

The Timken T151W tapered thrust roller bearing is engineered to support heavy unidirectional axial loads in industrial power transmission systems, gear drives, and heavy-duty machinery, delivering precise axial shaft positioning in gearboxes, rolling mills, machine tools, mining equipment, and construction machinery. This single-direction, TTCS tapered thrust bearing uses a separable design with a retainer drilled for oil holes (W designation) to improve lubrication under demanding conditions. Key specifications include bore 1.510 in (38.35 mm), outside diameter 2.859 in (72.619 mm), overall width 0.8438 in (21.433 mm), and a maximum shaft fillet radius of 0.030 in (0.8 mm). Rolling elements are tapered rollers and lubrication is oil- or grease-compatible; bearing material is high-quality bearing steel. The component supports a 10,600 lbf (47,000 N) axial load with a single-direction thrust orientation. Common replacements include Timken T151, Timken T151W-904A2, and SKF tapered thrust roller bearing equivalents, making it suitable for replacement, retrofit, and equipment overhaul in heavy industrial machinery such as steel processing equipment, mining systems, power transmission assemblies, and presses.
