How to read SKF NU 2307 ECP/C3
- NU 23Series
- Cylindrical roller bearings, NU 23 series. For the same bore, each series has a different outside diameter and width.
- 07Bore
- 35 mm bore: 07 × 5.
- ECP/C3Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
NU 2307 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF NU series cylindrical roller bearings are components designed to withstand high radial loads and considerable speeds. Their design with cylindrical rollers and polyamide cage allows precise and reliable operation in demanding industrial applications. They are ideal for machine tools, gearboxes, pumps and power transmission equipment, where radial load capacity and rigidity are essential.
The designation NU … ECP/C3 is interpreted as follows: NU indicates that the bearing has two ribs on the outer ring and none on the inner ring, which allows relative axial displacement. The number that follows is the size code according to the dimension series. ECP indicates an optimized design with polyamide cage and higher capacity rollers. C3 specifies an internal radial clearance greater than normal, suitable for applications with interference fits or elevated temperatures. For example, the number in the code corresponds to a bearing of the indicated series with these characteristics.
These bearings are used in a wide variety of industries in Argentina, such as metallurgy, cement, food and petrochemical. They are found in gearboxes, centrifugal pumps, compressors, industrial fans and machine tool spindles. Their ability to withstand heavy radial loads and their rigidity make them suitable for gear transmissions and applications requiring high precision and durability.
To select the appropriate bearing, take into account the radial load, rotation speed and environmental conditions. Sealing can be open or with protective plates, depending on contamination. Lubrication must be adequate: grease or oil, respecting maintenance intervals. Mounting requires precise alignment and correct adjustment of internal clearance, especially when using a polyamide cage. The NU series allows axial displacement, so it is important to consider the support configuration.
Regarding equivalences, cylindrical roller bearings from other brands can be interchanged if dimensions and tolerances match. When looking for replacements, verify the complete code, including suffixes such as ECP and C3, to ensure compatibility.

Frequently Asked Questions
- What are the dimensions of the SKF NU 2307 ECP/C3 bearing?
- The SKF NU 2307 ECP/C3 bearing has a 35 mm bore, a 80 mm outside diameter and a 31 mm width (35 x 80 x 31 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation NU 2307.
- What does the C3 suffix mean in an SKF NU bearing?
- The C3 suffix indicates an internal radial clearance greater than normal. It is used when the bearing operates at elevated temperatures or with interference fits that reduce clearance, thus avoiding overly tight operation.
- Does this bearing allow axial displacement?
- Yes, the NU series has two ribs on the outer ring and none on the inner ring, which allows the shaft to move axially relative to the housing. This is useful in applications where there is thermal expansion or need for axial freedom.
- What are typical applications for NU ECP/C3 bearings?
- They are used in gearboxes, pumps, compressors, fans and machine tools. Their capacity for high radial loads and their rigidity make them suitable for gear transmissions and equipment requiring precision and durability.
