Tapered roller bearings handle radial and axial loads simultaneously in one direction. Their cone shape creates a line of contact that spreads the load across a wider area than a ball bearing, so they carry heavier loads and run more rigidly. You will find them in gearboxes, reducers, wheel hubs and other machinery where the shaft must be guided precisely under load. MR Industrial Accessories supplies the NTN XU series.

Reading the NTN XU code is straightforward. The leading digits give the dimensional series and bore size. For instance, 32908XU2BC has a 40 mm bore; 32909XU2BC, 45 mm; 32913XU2BC, 65 mm; 32914XU2BC, 70 mm; 32915XU2BC, 75 mm; 32916XU2BC, 80 mm; 32917XU2BC, 85 mm; and 32918XU2BC, 90 mm. The XU suffix denotes an optimized internal geometry, while 2BC covers the tolerance and internal clearance combination. This lets you identify size and characteristics quickly.

In US plants, XU series bearings appear in many places: speed reducer gearboxes, machine tool spindles, commercial vehicle wheel ends, process pumps, industrial fans and material handling systems. They also serve food processing, cement, mining and oil operations where loads are heavy and conditions are tough. Because they take combined loads, they suit shafts that transmit power while also resisting axial forces.

Selecting the right bearing means matching it to the radial and axial loads, the rotational speed and the operating environment. Check sealing carefully: in dusty or wet areas, add seals or deflectors. Use proper tools during installation, apply force to the correct ring and avoid impacts that could damage the raceways. Follow the manufacturer's lubrication specification, and verify internal clearance and alignment during assembly to keep operation smooth and long-lasting.

Tapered roller bearings from different brands can be interchanged when the key dimensions and tolerances agree. For a replacement, compare bore diameter, outer diameter, total width and contact angle. Since designations differ between makers, it is wise to confirm equivalents with a specialist. At MR Industrial Accessories we help you find the equivalent bearing that fits your application and maintains original performance.
