Tapered roller bearings from SKF are built for situations where radial and axial forces act at the same time. The angled raceways and rollers create linear contact, which spreads the load across a wider area. They suit heavy-duty equipment such as industrial machines, transport units and drive systems. MR Industrial Accessories supplies this line and assists you in matching the right code to your application.
Reading the code helps you order the correct part. The series number changes with size, as in 31309 J2/QCL7CDF, 31313 J2/QCL7CDF and 31316 J1/QCL7CDF. The suffix after the slash identifies the internal design, for example J2/QCL7CDF or J1/QCL7CDF. Copy the entire designation from your drawing or from the old bearing and send it by WhatsApp.
These bearings appear in gearboxes, conveyor belts, mills, presses, earthmoving equipment and agricultural machinery. Because they manage combined loads, they are also found in wheel shafts, spindles and systems where radial and axial forces occur together. Industries such as food processing, metallurgy, cement and mining rely on them.
When choosing a bearing, consider the radial and axial load, the rotation speed and the operating environment. Proper alignment during assembly and the right lubrication for the application are important. The fit on the shaft and in the housing also influences performance. If you need help with these points, share your equipment data and we will assist you in defining the best option.
Tapered roller bearings are made to international standards, so they can be interchanged between brands. If you have a code from another manufacturer or an unidentified part, we can quote a suitable equivalent. MR supplies SKF bearings.

Frequently asked questions
- What kind of loads can tapered roller bearings handle?
- They are designed for combined radial and axial loads. The linear contact geometry distributes the load over a larger surface, making them suitable for applications with significant loads in both directions.
- How do I find the right code for my bearing?
- Look for the full code on the old bearing, on the drawing or in the equipment manual. It includes the series number and suffixes. If you do not have it, send us the main measurements and we will help identify it.
- Can I use an SKF bearing to replace one from another brand?
- Yes, tapered roller bearings are manufactured under international standards that allow interchangeability between brands. Send us the original brand code and we will quote the corresponding SKF equivalent.
