NSK TT series tapered roller bearings are components designed to support combined radial and axial loads. Their tapered roller geometry and inclined raceways distribute forces in demanding applications. They are used in industrial machinery, automotive and transmission equipment. At MR Accesorios Industriales we source them with the exact designation you need.
The NSK TT series is identified by the suffix TT that appears in the designation, as in *174TT3551 or *203TT4151. These alphanumeric codes combine numbers that refer to dimensions and design variants. The TT series groups tapered roller bearings with specific mounting and sealing characteristics. To correctly interpret each reference, it is essential to consult the drawings or the complete designation shown on the equipment.
These bearings are used in applications where combined loads and tilting moments exist, such as gearboxes, transmission shafts, machine tools and mining equipment. In Argentina, they are common in the automotive, cement and agricultural machinery industries. Their ability to support axial loads in one direction makes them suitable for paired mounting. The NSK TT series offers reliability under severe operating conditions.
To select the correct bearing, take into account the magnitude and direction of the loads, the rotational speed and the environmental conditions. Mounting requires precise alignment and proper adjustment of axial clearance, which is usually regulated by nuts or shims. Lubrication, whether with grease or oil, must be the one indicated for the working temperature. Effective sealing prevents contamination and extends bearing service life.
When looking for equivalents from other brands, it is important to compare not only the main dimensions (bore, outer diameter and width) but also the load capacity and contact angle. Tapered roller bearings are not universally interchangeable between manufacturers, although dimensional equivalents exist. Always verify the complete code and tolerances. At MR Accesorios Industriales we advise you to find the right option.
If you need an NSK TT series tapered roller bearing, write to us on WhatsApp with the code or dimensions. We will quote it promptly and indicate the compatible alternative if needed. We can also source other series and brands of bearings according to your requirement.

Frequently Asked Questions
- What does the TT suffix mean in NSK bearings?
- The TT suffix identifies a variant within the NSK tapered roller series. It may indicate design characteristics, such as contact angle or cage type. To interpret it correctly, it is necessary to consult the manufacturer's catalog or the complete designation.
- How do I choose the right tapered roller bearing?
- You should consider radial and axial loads, speed, temperature and available space. The type of mounting and lubrication are also key. With that data, we can advise you to select the correct code.
- Do you have equivalents from other brands?
- Yes, we can look for dimensional equivalents from other brands. It is important to compare not only the dimensions but also the load capacity and contact angle. Send us the code or dimensions and we will indicate the compatible alternative.
