NSK tapered roller bearings handle combined radial and axial loads in demanding industrial applications. The cone and cup geometry provides linear contact that distributes the load and delivers high load capacity. Typical uses include gearboxes, wheel hubs, and other machinery where forces are significant and rigidity is required. MR Industrial Accessories supplies this brand and can help you select the correct part number for your equipment.
These bearings are identified by a designation that combines letters and numbers. For instance, 362 A 58 and 394 A 69 belong to specific series, where the final digits indicate dimensions and design variants. The letter A often denotes particularities of the cone or cup. Having the complete code is essential to order the exact replacement. If you are unsure, send us the code from your equipment and we will quote the exact part.
Tapered roller bearings are found in gear reducers, pumps, fans, transmission shafts, and conveyor belt rollers across various industries, from metalworking and mining to agriculture and food processing. Their ability to support combined loads makes them suitable for demanding applications. MR Industrial Accessories serves these sectors throughout the United States and in several Latin American countries.
When selecting a bearing, consider the radial and axial load, rotation speed, and environmental conditions. Sealing and lubrication are critical; choose the cage type and internal clearance to match the application. Proper mounting must ensure precise alignment to avoid additional stresses. If you need assistance, our technical team can guide you. Contact us via WhatsApp or email with the code or dimensions of your part.
NSK tapered roller bearings can be interchanged with those from other leading brands if dimensions and design match. Always verify the complete code and tolerances. We can help you find the right equivalent if you provide the original part code. We work with major brands to offer a suitable solution.

Frequently asked questions
- How do I identify the tapered roller bearing I need?
- Check the code engraved on the bearing or in the equipment's technical data sheet. If you cannot find it, measure the inner diameter, outer diameter, and width, and send those dimensions via WhatsApp. With that data, we will quote the exact code.
- What is the difference between a tapered roller bearing and a ball bearing?
- A tapered roller bearing supports combined radial and axial loads and has greater load capacity. A ball bearing is used for lighter loads and higher speeds. The choice depends on the application and working conditions.
- Can I replace an NSK tapered roller bearing with another brand?
- Yes, as long as the dimensions and design match. It is essential to verify the complete code and tolerances. Send us the original code and we will help you find the correct equivalent.
