Claims (4)

1. Lejeanordning (2) til et landbrugsredskab (1) med henblik på drejelig lejring af et skiveformet værktøj (3), hvor lejeanordningen (2) omfatter et rulningsleje (6) med et stort antal rullelegemer (9), der ruller omkring af lejeakse (4) i et lejerum (10), hvor lejerummet (10) er tætnet i forhold til omgivelserne på en aksial ende (11) af lejeanordningen (2) ved hjælp af i det mindste en berørende tætning (21) og en berøringsfri tætning (12), hvor den berøringsfri tætning (12) dannes ved hjælp af en spalte (13) mellem et tætningslegeme (14) og en i forhold til tætningslegemet (14) drejelig værktøjsbærer (15), idet tætningslegemet (14) aksialt i det mindste delvist griber om bag en ydre kappeflade (16) på værktøjsbæreren (15) på en mod den aksiale ende (11) af lejeanordningen (2) vendt ende, kendetegnet ved, at der aksialt ved siden af tætningslegemet (14) i retning af en aksial midte af lejeanordningen (2) aksialt excentrisk er indrettet en spærrenot (17) i værktøjsbæreren (15), og en rand af tætningslegemet (14), hvilken rand er rettet aksialt mod lejeanordningens (2) midte, er affaset.
2. Lejeanordning (2) ifølge krav 1, kendetegnet ved, at tætningslegemet (14) strækker sig aksialt frem til en aksial rand af spærrenoten (17) .
3. Lejeanordning (2) ifølge krav 1 eller 2, kendetegnet ved et afdækningslegeme (25), der er forbundet ikke-drejeligt med værktøjsbæreren (15), og som i aksial retning i det mindste delvist radialt dækker spærrenoten (17).
4. Lejeanordning (2) ifølge et af de foregående krav, kendetegnet ved, at spærrenoten (17) har et rektangulært, et U-formet, et V-formet eller et trapezformet tværsnitsprofil, eller at der vinkelret på lejeaksen (4) er anbragt en notflanke, der ligger nærmere ved lejeanordningens (2) aksiale midte, og en notflanke, der ligger længere væk fra lejeanordningens (2) aksiale midte, er anbragt sådan i en vinkel til lejeaksen (4), at noten udvider sig fra en notbund hen til en notåbning.
