The SKF NJ series cylindrical roller bearing with ECML suffix is a component designed to withstand high radial loads and considerable speeds. Its cylindrical roller design and machined brass cage make it suitable for demanding applications in industrial machinery. MR Accesorios Industriales offers this line as part of its SKF bearing catalog.
The designation NJ … ECML is interpreted as follows: NJ indicates that the bearing has one rib on the inner ring and two ribs on the outer ring, allowing axial guidance in one direction. The number that follows is the size code according to the dimension series. The suffix EC indicates an optimized design with higher load capacity, and ML specifies a machined brass cage, suitable for high speeds and temperatures. For example, NJ 220 ECML combines these features in a specific size.
These bearings are used in applications where radial loads are predominant and high rigidity is required. They are common in gearboxes, industrial pumps, compressors, machine tools and power transmission equipment. In Argentina, they are found in the metallurgical, food, cement and oil & gas industries, where reliability and the ability to withstand heavy loads are critical.
To correctly select an NJ ECML bearing, take into account the radial load, rotational speed and environmental conditions. Sealing will depend on the contamination present; in dirty environments additional protection is recommended. Lubrication must be suitable for the operating speed and temperature. During assembly, it is essential to align the rings and avoid impacts that could damage the rollers or cage. Incorrect fitting can reduce bearing life.
SKF NJ ECML cylindrical roller bearings can be interchanged with equivalent products from other brands that follow the same dimensions and designation. However, load capacities and cage materials may vary between manufacturers. Always verify the technical specifications of the replacement to ensure compatible performance. MR Accesorios Industriales can advise you on the best option for your application.

Frequently Asked Questions
- What are the dimensions of the SKF NJ 2228 ECML bearing?
- The SKF NJ 2228 ECML bearing has a 140 mm bore, a 250 mm outside diameter and a 68 mm width (140 x 250 x 68 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NJ 2228.
- What does the ECML suffix mean on an SKF bearing?
- EC indicates an optimized design with higher radial load capacity. ML refers to a machined brass cage, which allows high speeds and withstands elevated temperatures. Together, these suffixes identify a specific variant within the NJ series.
- Does this bearing support axial loads?
- Yes, but only in one direction, due to the rib on the inner ring. For axial loads in both directions, configurations with other bearings or combinations are required. Consult MR to evaluate your particular case.
- How do I request a quote for this bearing?
- Send the complete part number, for example NJ 220 ECML, via WhatsApp to MR Accesorios Industriales. We will respond with the information you need to make your purchase.
