Timken 388DA Double-Row Tapered Roller Bearing Cone

The Timken 388DA double-row tapered roller bearing cone delivers high radial and thrust capacity for heavy-duty rotating equipment, making it a reliable choice for industrial gearboxes, rolling mills, mining equipment, construction machinery, and material handling systems. This cone has a 2.2650 in (57.531 mm) bore and a per-cone inner ring width of 0.8640 in (21.946 mm), with a maximum shaft fillet radius of 0.140 in (3.600 mm). Its dynamic radial load rating is 24,200 lbf (108,000 N) and C90 is 6,280 lbf (28,000 N), with a static radial rating of 24,100 lbf (107,000 N) and a dynamic thrust rating of 3,810 lbf (16,900 N); it uses a stamped steel cage and through-hardened bearing steel for durability, and weighs approximately 5.5 lb (2.5 kg). The part number is 388DA from Timken, commonly used as replacement in SKF 388DA, NTN 388DA, and KOYO 388DA applications for repairs, retrofits, and drivetrain reliability in industrial gearboxes and heavy equipment.
