For equipment that handles both radial and axial forces at the same time, NTN 4T series tapered roller bearings are a common choice. Their tapered rollers and angled raceways create linear contact that spreads the load across the bearing. You will find them in gearboxes, reducers, wheel axles, and a wide range of industrial machinery. MR Industrial Accessories supplies this line to customers throughout the United States and Latin America, and can help you match the right code to your application.

The 4T series uses a cup-and-cone format. In a designation such as 4T-6559C/6535, the first part (6559C) is the cone and the second (6535) is the cup. Similarly, 4T-55175C/55437 pairs cone 55175C with cup 55437. The letter C on a cone typically signals a design variant, while the numbers identify the individual components. Understanding this structure makes it easier to order an exact replacement or a suitable equivalent.

These bearings appear in food processing, metallurgy, mining, and agriculture, as well as in automotive and railway equipment. Typical installations include speed reducers, conveyor belts, mills, presses, and earthmoving machines. Because they accommodate combined loads, they suit shafts that see radial and axial forces at the same time, as long as mounting and lubrication are done correctly.

When selecting a bearing, consider the radial and axial load, the rotation speed, and the operating environment. Seals or protective plates help keep contaminants out; in dirty conditions, effective sealing is especially important. Use the lubricant specified by the manufacturer, and pay attention to alignment and axial clearance during mounting. Poor installation can shorten service life.

NTN 4T series bearings can be interchanged with other brands that follow the same standardized dimensions, such as SKF, FAG, or Timken, provided the bore diameter, outer diameter, and width match. The complete designation and tolerances determine whether a direct swap is possible. If you have a code from another brand, we can identify the NTN equivalent and quote it for you.
