The SKF radial shaft seal of the CRSA P series is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles, protecting bearings and bushings. It is press-fitted into the housing and works on the shaft with a flexible lip that compensates for small misalignments. It is a key part in industrial maintenance because it extends the service life of components and reduces unplanned downtime.

The designation of these seals combines dimensions and suffixes. In the example 125X146X14 CRSA1 P, the numbers indicate shaft diameter, outer diameter and width, in millimeters. The letters CRSA identify the construction family, while the final number and the letter P indicate lip and material variants. To choose the correct seal, always compare the three dimensions and the full code; a difference in the suffix can change the type of elastomer or the spring.

They are used in pumps, electric motors, reducers, conveyor belts, agricultural machinery and process equipment. In food, chemical and petrochemical plants, sealing prevents leaks and cross-contamination. They are also common in maintenance workshops that replace seals in gearboxes and rollers. The CRSA P series covers applications with moderate peripheral speeds and medium sealing requirements, typical of Argentine industry.

To select, check the shaft diameter, the housing and the available width. The lip must remain lubricated; if the seal runs dry, it wears quickly. Alignment between shaft and housing is critical: an eccentricity greater than the allowable one causes leakage. During installation, use a tool that presses on the outer edge and avoid striking the lip. If the shaft is worn, consider a seal with an auxiliary lip or a repair sleeve.

Radial shaft seals are interchangeable between manufacturers if the dimensions and lip type match. The diameter alone is not enough: the width and the shape of the lip must be compatible. Brands such as SKF, NSK, Timken or NTN offer equivalents, but always verify the full code. At MR Accesorios Industriales we carry SKF as an official brand and can guide you if you send us the dimensions or the code engraved on the old part.

Before requesting a quote, check the condition of the shaft and the housing. A new seal does not seal well on a scratched or loose shaft. Send us the full code on WhatsApp, along with the dimensions if you have them, and we will reply with the available alternative. We work with more than 80 years of experience in the field and advise workshops and plants throughout Argentina.
