SKF LL series tapered roller bearings are built to handle combined radial and axial loads in a single direction. The tapered rollers running on angled raceways give the bearing the rigidity and load capacity needed in demanding assemblies. You will find them in industrial machinery, power transmission equipment and anywhere axial clearance has to be set with precision.
Reading the code is straightforward once you know the pattern. The LL prefix comes first, then a series number, and sometimes a bore number. In LL 483448/418, LL marks the series and the digits that follow identify the cone-and-cup assembly. In LL 639249/210, the first group of digits is the cone and the second is the cup. Before you pick a bearing, confirm the mounting dimensions and the loads it will see.
These bearings show up across metallurgy, cement, mining and food processing operations. Gearboxes, conveyor belts, mills, presses and material handling equipment commonly use them. Because they take combined loads, they suit shafts that transmit power and need high axial rigidity.
Selection starts with the radial and axial loads, the rotational speed and the conditions around the bearing. Mounting has to hold precise alignment, and axial clearance must be adjusted following the manufacturer's recommendations. Choose a lubricant that matches the operating temperature and speed. If the bearing comes with seals or shields, make sure they suit the working environment.
For replacements, tapered roller bearings from other brands may carry equivalent designations. Whether they interchange depends on dimensions and tolerances, so compare the technical specifications. If you only have another brand's code or a part you cannot identify, we can help you find the equivalent.
To get a quote, send the code or the dimensions by WhatsApp or email to MR Industrial Accessories. We reply promptly with the technical and commercial information you need. Tell us the operating conditions of your equipment and we can also advise on the right selection.

Frequently asked questions
- Where are SKF LL series tapered roller bearings used?
- They are common in gearboxes, conveyor belts, mills, presses and material handling equipment. They handle combined radial and axial loads in one direction, which makes them a fit for power-transmitting shafts that need high rigidity.
- How do I choose the right LL series bearing for my equipment?
- Start with the mounting dimensions, the radial and axial loads, the speed and the environmental conditions. With those details we can guide you to the correct code within the LL series.
- Can I replace another brand's bearing with an SKF LL series bearing?
- It can be done when the dimensions and tolerances line up. Send us the original brand's code or the dimensions and we will identify the equivalent in SKF's LL series.
