Timken NA52375 Double Row Tapered Roller Bearing

The Timken NA52375 double-row tapered roller bearing cone (inner ring assembly) is a heavy-duty component designed to support combined radial and axial loads in demanding industrial equipment such as gearboxes, rolling mills, and conveyors. It features a 3.7500 in bore and an inner ring width across cones of 3.2499 in when assembled (inch design), uses a steel cage, and is made from high-grade bearing steel for durability. Key ratings include dynamic radial load C1 of 87,500 lbf (389,000 N), dynamic radial C90 of 13,000 lbf (57,900 N), dynamic two-row radial C90-2 of 22,700 lbf (101,000 N), and dynamic axial Ca90 of 10,600 lbf (47,100 N), with an approximate weight of 14.41 lb (6.53 kg). Compatible with Timken 52637D double cup and part of the NA52375-52637D bearing assembly, it is commonly used in mining equipment, industrial gearboxes, steel processing machinery, conveyors, heavy-duty pumps, and paper mills requiring precise shaft positioning and reliable service life.
