TSN A end covers are used to close split bearing housings. Mounted on both sides, they keep lubricant within the housing cavity and block the ingress of dust, water, and particles. These covers are a common selection for housings operating in moderately dirty or damp conditions.
The TSN prefix denotes the end cover family for split housings. The following number, such as in TSN 206 A, TSN 210 A, or TSN 213 A, corresponds to the housing size it matches. The A suffix indicates a construction variant within the series. To select the correct cover, begin with the part number of the installed housing or the bearing being housed, and confirm compatibility against that reference.
Typical applications include conveyor belts, bucket elevators, mills, mixers, centrifugal pumps, and industrial fans, particularly where the housing faces weather or dust. In food processing, cement, mining, aggregate, and agro-industrial plants, the added sealing helps extend bearing life and reduce relubrication intervals.
When choosing a TSN A end cover, verify that the housing diameter and shape align with the cover. Fastening is done with the same bolts as the housing or with dedicated bolts, depending on the design. Ensure the sealing lip sits evenly on the shaft without misalignment. Proper cavity lubrication and using covers on both sides improve lubricant retention and contaminant exclusion.
SKF TSN A end covers can be interchanged with equivalent covers from other manufacturers if mounting dimensions and sealing type match. Similar part numbers are not sufficient; compare outside diameter, shaft bore, and fastening method. If unsure, provide the housing and bearing part numbers for verification.

Frequently asked questions
- How do I identify the correct TSN A end cover for my housing?
- Use the housing or bearing part number as a starting point. The cover must match in diameter and fastening shape. If you lack that information, send a photo or the housing dimensions and we will assist.
- Are TSN A end covers appropriate for dusty or wet conditions?
- They are designed to protect the bearing from dust and splashes. For heavy water exposure or washdown, consider additional seals or labyrinth end covers. Contact us to discuss your application.
- Can I use a TSN A end cover to replace one from another brand?
- Yes, if mounting dimensions and sealing type are compatible. Do not rely on the number alone; compare outside diameter, shaft bore, and fastening. Send us the details and we will verify before quoting.
