The Timken Company 14137-A 14277 Tapered Bearing Cone and Cup

The Timken 14137-A / 14277 tapered roller bearing assembly is a single-row TS-design bearing pair that supports combined radial and axial loads while maintaining precise shaft alignment in demanding industrial machinery. The assembly consists of the Timken 14137-A cone and Timken 14277 cup, engineered to operate together as a matched bearing set. Key dimensions include a bore of 1.3750 in (34.925 mm) and an outside diameter of 2.7170 in (69.012 mm), with an overall width of 0.8813 in (22.385 mm). Cone width is 0.7710 in (19.583 mm) and cup width is 0.7250 in (18.415 mm). The bearing’s dynamic radial load rating is 12,300 lbf (54,600 N) and static radial load rating is 13,900 lbf (61,700 N). The cage is pressed steel, and the assembly weight is approximately 0.80 lb (0.40 kg). Commonly used in conveyor drive systems, industrial gearboxes, agricultural and construction equipment, machine tools, and other power transmission systems where accurate shaft positioning and long service life are essential.
