Timken NTA-2031 Thrust Needle Roller Bearings

Timken NTA-2031 thrust needle roller bearing delivers robust axial load support in compact, space-limited assemblies where a minimal cross-section is essential. This needle roller thrust bearing uses a needle roller and cage assembly, is made from hardened bearing steel, and is designed to operate with compatible TRA-2031 thrust washers to deliver low-friction, high-load performance. Key specs: bore 1.250 in (31.75 mm); outside diameter 1.937 in (49.20 mm); width 0.0781 in (1.984 mm). Dynamic load rating 4,530 lbf (20.15 kN); static load rating 21,000 lbf (93.41 kN); limiting speed 8,600 rpm. Common replacements include Timken NTA-2031 with TRA-2031 thrust washers, SKF NTA-2031, and NTN NTA-2031. Typical applications span automotive transmissions and gearboxes, machine tools, pumps, compressors, and other industrial power transmission equipment where reliable thrust load capacity and smooth axial motion are needed. Maintenance teams, OEMs, and system integrators rely on this bearing for replacement, repair, retrofit, and equipment overhaul to restore axial motion and extend service life.
