How to read SKF 7318 BECBJ
- 73Series
- Angular contact ball bearings, 73 series. For the same bore, each series has a different outside diameter and width.
- 18Bore
- 90 mm bore: 18 × 5.
- BECBJSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
7318 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 7318 BECBJ bearing has a 90 mm bore, a 190 mm outside diameter and a 43 mm width (90 x 190 x 43 mm).

SKF angular contact bearings are components designed to support combined radial and axial loads. Their design with offset raceways allows them to handle forces in both directions, making them ideal for applications where precision and rigidity are critical. At MR Accesorios Industriales we sell this line for the Argentine industrial market.
The designation of these bearings follows a standardized system. In the example 7204 BECBJ, the prefix 72 indicates the dimension series, which in this case corresponds to a medium section. The number 04 indicates the bore size, which multiplied by 5 gives the bore diameter in millimeters. The suffixes BECBJ define internal characteristics: B for the 40° contact angle, E for the optimized design, CB for reduced internal clearance and J for the steel sheet cage. This coding makes it possible to quickly identify the particularities of each variant.
These bearings are used in a wide variety of industrial applications. In Argentina, they are common in centrifugal pumps, compressors, gearboxes, machine tool spindles and power transmission equipment. They are also used in the food, petrochemical and automotive industries, where combined loads must be supported with high precision. Their ability to run at high speeds makes them suitable for electric motors and gear reducers.
To correctly select an angular contact bearing, it is essential to consider the magnitude and direction of the loads, the operating speed and the environmental conditions. Mounting must be carried out with precise alignment, since these bearings are sensitive to misalignment. Sealing and lubrication are key aspects: in contaminated environments additional protection is recommended. The internal clearance, indicated by suffixes such as CB, must be chosen according to the application to ensure optimal operation.
As for equivalents, SKF angular contact bearings can be interchanged with those of other brands that follow the same dimensional designation. However, suffix letters may vary between manufacturers, so it is important to verify the technical specifications before replacing a bearing. At MR Accesorios Industriales we can advise you on interchangeability for your equipment.

Frequently Asked Questions
- What are the dimensions of the SKF 7318 BECBJ bearing?
- The SKF 7318 BECBJ bearing has a 90 mm bore, a 190 mm outside diameter and a 43 mm width (90 x 190 x 43 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 7318.
- What does the BECBJ suffix mean on an SKF bearing?
- The BECBJ suffix indicates internal characteristics: B for a 40° contact angle, E for optimized design, CB for reduced internal clearance and J for a steel sheet cage. These details define the performance and application of the bearing.
- How is the bore diameter of a 7204 bearing calculated?
- The bore diameter is obtained by multiplying the size number by 5. In the case of 7204, the bore diameter is 20 mm. This rule applies to most bearings with a numeric designation.
- Where are angular contact bearings used?
- They are used in applications with combined loads, such as pumps, compressors, gearboxes and machine tool spindles. Also in electric motors and gear reducers that require high precision and rigidity.
