NTN tapered roller bearings handle radial and axial loads in one direction. The tapered races and rollers create linear contact that distributes the load across the bearing. You will find them in gearboxes, wheel axles and agricultural machinery, where motion has to be transmitted under demanding conditions. MR Industrial Accessories LLC supplies the NTN line to customers across the United States and in several Latin American countries.

The part number tells you what you are holding. In 4T-A4050/A4138, the 4T prefix identifies a single-row tapered roller bearing, A4050 is the cone and A4138 is the cup. A suffix such as † in 4T-A4059†/A4138 points to a variant with special manufacturing characteristics. Reading these codes correctly lets you order the exact replacement or ask for an equivalent size.

These bearings appear in food processing, metallurgy, mining and agriculture. They are common in seeders, harvesters, conveyor belts, pumps and industrial fans, as well as in earthmoving equipment and automotive applications. Their ability to work with controlled misalignment and combined loads makes them suitable for demanding environments.

Selection depends on the radial and axial load the bearing will see, the rotation speed and the operating conditions. Mounting calls for precise alignment between cone and cup and the right lubrication for the regime. Sealing matters to keep contaminants out; in dusty or humid locations, add extra seals. Follow the equipment manual for preload and internal clearance.

NTN tapered roller bearings can be interchanged with other brands when dimensions and contact angle match. Check the complete part number, because small suffix changes alter the internal geometry. If you have a part number from another brand, our team can help you find the equivalence.
