SKF radial shaft seals in the CRS line with the V suffix are single-lip seals designed to retain lubricant and block the ingress of dust and water on rotating shafts. They are used in gearboxes, pumps, electric motors and power transmission equipment, where shaft sealing is critical to prevent oil loss and bearing contamination. MR Accesorios Industriales carries them as part of its industrial seals line.

The designation of these seals is read from left to right: first the shaft diameter, then the outside diameter and finally the width, always in millimeters. Thus, 20X30X7 CRS1 V corresponds to a seal for a 20 mm shaft, 30 mm housing and 7 mm width; 30X45X8 CRS1 V follows the same criteria for a 30 mm shaft. The CRS block identifies the single-lip family and the V suffix indicates the elastomer variant and the lip type. Before ordering, verify those three dimensions on the drawing or on the original part.

These seals appear across a wide range of Argentine industry: gearboxes and motovibrators, centrifugal pumps, fans, conveyor belts, machine tools and process equipment. They are also found in the food and beverage sector, where sealing prevents lubricant from migrating into the product, and in mining and cement applications, where ambient dust demands a lip that seals well against the shaft. In all those cases they serve the same function: separate the lubricant from the environment and extend bearing life.

To choose well, first look at the condition of the shaft: a new seal on a scratched or burred shaft will not seal. Verify that the shaft diameter is within the recommended tolerance, that the housing has no burrs and that the lip sits centered. Pre-lubricating the lip with the same grease or oil used in the equipment makes installation easier and prevents dry start-up. If the seal operates at high peripheral speed or temperature, check the appropriate elastomer variant. Shaft alignment with respect to the housing also affects service life.

As for interchangeability, radial shaft seals are identified by their dimensions in millimeters and by the lip type, not by a single universal code. Different manufacturers use their own nomenclatures, but a 20X30X7 single-lip seal can replace another with the same dimensions and the same lip configuration, provided the material is compatible with the fluid and the operating temperature. Matching the three dimensions is not enough: the lip type and the elastomer must also be compared.

If you have the seal part number at hand, send it via WhatsApp to MR Accesorios Industriales along with the dimensions or a photo of the part. With that data we will confirm the corresponding CRS/V variant and send you the quote. If you cannot find the part number, send the shaft diameter, outside diameter and width; those three dimensions are enough to identify it.
