The Timken Company T302 Tapered Roller Thrust Bearing

The Timken T302 tapered roller thrust bearing, a single-direction unit in the TTC Series, is manufactured by Timken to support heavy axial loads while maintaining accurate shaft alignment in demanding industrial rotating equipment. It is commonly installed in gearboxes, rolling mills, industrial presses, machine tools, and power transmission systems, where dependable thrust load capacity, minimized friction, and long operating life extend equipment service life. Maintenance teams, OEMs, and system integrators rely on the T302 for replacement, repair, retrofit, and equipment overhaul to restore reliable axial load support and extend service life. Key specifications include bore diameter 3.010 in (76.45 mm), outside diameter 5.250 in (133.35 mm), width 1.375 in (34.93 mm), Oil Holes in Retainer: No, Maximum Shaft Fillet Radius: 0.090 in (2.30 mm), Steering Pivot Rating: 40,000 lbf (178,500 N); the design is separable to simplify installation and maintenance. Common replacements include Timken T302-904A2, SKF tapered roller thrust bearing equivalents, and NTN tapered roller thrust bearing equivalents.
