SKF radial shaft seals of the CRS R series are lip seals designed to prevent lubricant leakage and the ingress of contaminants on rotating shafts. They are used in gearboxes, pumps, electric motors and a wide variety of industrial equipment. MR Accesorios Industriales supplies this line as an official brand, with more than 80 years of experience in the field.

The designation of these seals combines the main dimensions and the series code. For example, 9X17X4.50 CRS11 R indicates an inner diameter of 9 mm, outer diameter of 17 mm and width of 4.50 mm, followed by the CRS11 reference and the R suffix. In 80X115X13 CRS13 R, the inner diameter is 80 mm, the outer diameter 115 mm and the width 13 mm. The number accompanying CRS identifies construction variants within the series, while the final letter R indicates a specific feature of the lip or material, according to the SKF design. Always verify the full code before ordering.

These seals are used in applications with continuous rotation and the need to retain oil or grease. They are common in gear reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In Argentine industry they appear in food, chemical, petrochemical and general manufacturing plants. They are also used in agricultural and road machinery, where dust and moisture demand reliable sealing. Their function is to protect bearings and gears, extending the service life of the assembly and reducing maintenance downtime.

To select the right seal, take into account the shaft diameter, housing diameter and available width. It is essential that the shaft surface be ground and have adequate hardness to avoid premature lip wear. Lubricating the lip before mounting helps ensure correct seating. Check alignment between shaft and housing; excessive misalignment accelerates failure. If the equipment operates with a lot of dirt, consider seals with an auxiliary lip or dust guard. Temperature and fluid type also determine the choice of lip material.

When looking for a replacement, always compare dimensions and lip type. Metric sizes are standard, but equivalents from other brands with the same basic designation may exist. Do not rely only on the code: verify that the inner diameter, outer diameter and width match the original seal. At MR Accesorios Industriales we can guide you on interchangeability and the options available in SKF. Remember that correct installation, with suitable tools, is key to avoiding lip damage and ensuring sealing.
