Tapered roller bearings from FAG in the XL, DF and A series carry radial and axial loads at the same time. Reading the code tells you what you are holding: XL marks the current optimized design, DF means the pair is matched face to face, and the A range gives the axial adjustment window. Gearbox housings, machine tool spindles and mining equipment are typical homes for these units. MR Industrial Accessories LLC supplies the line and helps you match the number to the application.

A part number in this series is built in layers. The base number, two or three digits, sets the size and the contact angle. The suffixes then describe the design and how the pair is mounted. Take 30212-XL-DF-A100-140: 30212 is the metric tapered roller size, XL is the optimized current design, DF is the face-to-face matched pair, and A100-140 is the axial adjustment range. In 31308-XL-DF-A50-90 the base 31308 fixes dimensions and capacity, and the suffixes follow the same pattern. One string of characters therefore carries size, design and mounting information.

Where do these bearings work? Speed reducers, drive shafts, conveyor rollers, mills and pumping equipment are common locations, along with gearboxes and machine tool spindles where internal clearance and alignment decide how the assembly performs. Industries such as metalworking, mining, cement and food processing rely on them. Combined load support and rigidity are the reasons they are specified in assemblies that demand precision.

Selection starts with radial and axial load, rotational speed and the working environment. The DF face-to-face arrangement compensates moment and suits assemblies that need rigidity in both directions. Sealing and lubrication follow the contamination level and operating temperature. At mounting, check shaft alignment and the recommended axial clearance, because poor adjustment shortens service life. The XL version brings design changes to rollers and raceways.

On interchangeability, tapered roller bearings are made to international standards, so brands can often be swapped. Compare bore, outer diameter and width, plus contact angle and load capacity. Suffix conventions differ from one maker to another even when the basic designation lines up. For matched sets, keep the arrangement and the stated adjustment range. The complete original part number remains the safest reference when you need an equivalent.
