SKF NJ series cylindrical roller bearings are components designed to withstand high radial loads and high speeds. Their design with cylindrical rollers and polyamide cage allows precise and reliable operation in demanding industrial applications. MR Accesorios Industriales offers this line as part of its broad range of bearings and power transmission components.
The NJ designation identifies cylindrical roller bearings with one rib on the inner ring and two ribs on the outer ring, allowing axial guidance in one direction. The ECP and C3 suffixes provide key information: EC indicates an optimized design with higher load capacity, P indicates that the cage is made of polyamide, and C3 specifies an internal radial clearance greater than standard. For example, NJ 204 ECP/C3 combines these features in a bearing with a 20 mm bore diameter.
These bearings are used in a wide variety of industrial applications in Argentina, such as gearboxes, pumps, compressors, electric motors, machine tools and mining equipment. Their ability to withstand heavy radial loads and high speeds makes them ideal for power transmissions and roller systems in production plants. They are also used in the food, petrochemical and automotive industries, where reliability is critical.
To select the right bearing, take into account the radial load, rotation speed and environmental conditions. The C3 suffix is recommended when thermal expansion or interference fits are expected. Sealing will depend on contamination: in dirty environments, choose bearings with seals or shields. Lubrication must be suitable for the operating speed and temperature. During assembly, ensure precise alignment and avoid impacts that could damage the rollers or raceways.
As for equivalents, SKF NJ series cylindrical roller bearings can be interchanged with those from other brands that follow the same dimensional and suffix designation, such as FAG, NSK or NTN. However, always check tolerances and radial clearance, as they may vary between manufacturers. MR Accesorios Industriales offers SKF as a brand, with technical support.

Frequently Asked Questions
- What are the dimensions of the SKF NJ 2315 ECP/C4 bearing?
- The SKF NJ 2315 ECP/C4 bearing has a 75 mm bore, a 160 mm outside diameter and a 55 mm width (75 x 160 x 55 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NJ 2315.
- What does the C3 suffix mean on an SKF NJ bearing?
- The C3 suffix indicates an internal radial clearance greater than standard. It is used when the bearing will operate at high temperatures or when mounting fits reduce clearance, thus avoiding excessive preload.
- What is the difference between the ECP and EC suffixes on SKF bearings?
- EC indicates an optimized design with higher load capacity. The added letter P means the cage is made of polyamide, which reduces weight and improves performance at high speeds. Both suffixes can appear together as ECP.
- Can I replace an SKF NJ bearing with one from another brand?
- Yes, as long as the dimensional designation and suffixes match. Brands such as FAG, NSK or NTN offer equivalents. However, check tolerances and radial clearance, as they may vary. Contact us via WhatsApp for advice.
