SKF radial shaft seals of the CRWA R line are lip seals designed for rotating shafts. Their function is to retain lubricant and exclude contaminants in gearboxes, pumps, electric motors and reducers. The CRWA R designation indicates a profile with a sealing lip and spring, suitable for applications requiring low friction and good wear resistance. They are mounted in cylindrical housings and adapt to shafts with specific tolerances. MR Accesorios Industriales sells this line.

The designation of these seals follows the format inner diameter x outer diameter x width, followed by the series code. For example, 16X40X7 CRWA1 R indicates a seal for a 16 mm shaft, 40 mm housing and 7 mm width. The suffix CRWA R identifies the lip geometry and the spring type. In the series, the number following CRWA usually indicates a single lip section, while the final R refers to the presence of a steel spring. The examples in the table cover a range of sizes from 16 mm to 90 mm inner diameter.

These seals are used in a wide variety of industrial equipment in Argentina: speed reducers, centrifugal pumps, electric motors, compressors, machine tools and gear transmissions. They are also present in the food, chemical and petrochemical industries, where reliable sealing prevents oil leaks and the entry of dust or water. Their radial design makes them suitable for shafts rotating at moderate and high speeds, with low pressures on the fluid side.

To correctly select a CRWA R seal, take into account the shaft diameter, housing diameter and seat width. It is essential to verify the roughness and hardness of the shaft, since a worn or grooved shaft can damage the lip. During mounting, lubricate the lip with the same service oil or grease, and insert the seal perpendicular to the shaft to avoid deformation. The alignment between shaft and housing must be precise; excessive misalignment accelerates wear. If the seal incorporates a spring, make sure it remains on the fluid side to be retained.

Regarding equivalences, SKF CRWA R seals can be interchanged with products from other brands that follow the same dimensional designation and lip type. Equivalents are commonly found in catalogs from manufacturers such as NAK, TTO or Corteco, but always verify the tolerances and lip material, as they may vary. Interchangeability is not automatic: check that the lip profile, spring and elastomer are compatible with the fluid and operating temperature. If in doubt, consult our technical team.
