Tapered roller bearings from NTN are built to carry radial and axial forces acting in one direction. The angled rolling elements make line contact with the races, which spreads the load across a wider area and suits equipment where both types of force occur at once. NTN controls tolerances on this line to support accurate, consistent running. MR Industrial Accessories LLC assists buyers in matching the correct bearing to their machinery.

The part numbering system uses a mix of letters and digits. Take 4T-T4CB100, 4T-T4CB120 and 4T-T4CB140: all three are single-row tapered roller bearings. The 4T at the start marks a particular NTN variant, T4CB identifies the dimensional series, and the trailing figures (100, 120, 140) tie to the bore or assembly size. Reading these codes correctly speeds up the quoting process.

You will find these bearings in gearboxes, drive shafts, road machinery, agricultural equipment and conveyors, as well as in food, mining and petrochemical plants. Because they accept axial load in a single direction, they work well in paired arrangements or alongside an opposing bearing. MR Industrial Accessories LLC serves customers throughout the United States and in several Latin American countries.

Selecting the right unit means checking the radial and axial loads, the operating speed and the surrounding conditions. Installation calls for accurate alignment and correct adjustment of internal clearance, which is set by moving the races axially. Lubrication has to match the temperature and speed of the application. Good sealing keeps contaminants out and helps the bearing last.

Tapered roller bearings follow international standards, so brands can often be interchanged. To replace a bearing from another maker, compare bore, outer diameter, width and contact angle, and confirm the full designation and tolerance class. MR Industrial Accessories LLC can suggest equivalents and help you choose, and also offers its own manufacturing of split plummer block housings, roller chains and sheaves.
