For rotating shafts, the SKF CRWHA R radial shaft seal keeps lubricant in and contaminants out. It suits gearboxes, pumps, electric motors and transmission equipment where oil or grease must stay within the housing. The design pairs a sealing lip with a metal outer body and adds a cover that shields the lip in dusty or dirty conditions.
Codes in this series carry both dimensions and suffixes. Take 66X85X10 CRWHA1 R: bore 66 mm, outer diameter 85 mm, width 10 mm. CRWHA denotes the series, with a variant that includes an auxiliary exclusion lip and an external metal cover; the trailing R specifies the lip elastomer. When selecting, match all three dimensions and the full suffix, since each combination determines fit and sealing behavior.
You will find these seals in gear reducers, centrifugal pumps, electric motors, compressors and chain or belt drives. Agricultural equipment such as seeders and harvesters, plus road machinery, also uses them. The CRWHA R series handles dust, water and chips well because its exclusion lip blocks abrasive particles before they reach the bearing or housing.
Selection starts with shaft diameter, housing diameter and available width. The lip needs a ground, lubricated surface; if the shaft is worn, consider a wear sleeve or a new location. Shaft-to-housing alignment matters, as too much misalignment speeds lip wear. Coating the lip with compatible grease before installation eases fitting and avoids early damage. Permissible peripheral speed depends on lip material and lubricant type.
Seals from different manufacturers can interchange when dimensions and construction type align. During replacement, check not just sizes but also lip material, auxiliary lip and cover style. A seal with an exclusion lip can stand in for a simple one in dirty settings, but not the reverse. A specialist can pinpoint the right option within the same series or an equivalent.

Frequently asked questions
- How do I identify the seal I need?
- You need the shaft diameter, housing diameter and width. With those three dimensions and the original code, if available, we can identify the correct series and suffix. Lubricant type and environmental conditions also matter.
- What does the suffix CRWHA R mean?
- CRWHA indicates a construction with an exclusion lip and external metal cover; the final R identifies the lip material. That combination defines protection against contaminants and compatibility with different lubricants.
- Can it be replaced by another brand?
- Yes, if dimensions and construction type match. Verify that lip material and the presence of an auxiliary lip are equivalent. A specialist can confirm interchangeability based on the code and application.
