1. Kuglekrans (30) til et rulleleje med en løbebane (14; 15) til i det mindste en rullelegemerulle (13) og en til udledning af aksiale kræfter på en endeside af løbebanen placeret kant (31) , som strækker sig væk fra løbebanen og har en anløbsflade (32) , der vender hen mod løbebanen (14; 15) til rullelegemeruller (13), hvis krumning falder strengt monotont fra et startpunkt (33) til en ende (34) på anløbsfladen, idet startpunktet (33) er placeret mellem en indvendig, til løbebanen tilgrænsende ende (36) på anløbsfladen (32) og en udvendig, fra løbebanen bortvendt ende (34) på anløbsfladen (32), og krumningen af anløbsfladen (32) fra startpunktet (33) og hen til begge ender på anløbsfladen (32) hver især falder strengt monotont, eller idet startpunktet (33) er placeret i den indvendige ende (36) , som grænser op til løbebanen, på anløbsfladen (32).
2. Kuglekrans (30) ifølge krav 1, idet en vinkel (ex) mellem et tangentialplan (38) ved enden (34) af anløbsfladen (32) og et andet tangentialplan ved en fra startpunktet (33) hen til enden af anløbsfladen (32) forlænget kugleoverflade (40) med en krumning svarende til krumningen ved startpunktet ligger i et område på større end als 0° til 30°.
3. Kuglekrans (30) ifølge et af de foregående krav, idet rullelejet er et keglerulleleje til anvendelse med en keglerulle (13).
4. Kuglekrans (30) ifølge et af de foregående krav, idet kuglekransen (30) er en indvendig kuglekrans.
5. Rulleleje med en indvendig kuglekrans (30) ifølge et af kravene 1 til 4 samt med i det mindste en keglerulle (13).
6. Rulleleje ifølge krav 5, hvor i det mindste en keglerulle på det overfladeområde på den, som vender mod anløbsfladen (32), har en krummet overflade (21) med en konstant krumning.
7. Fremgangsmåde til fremstilling af en kuglekrans (30) til et rulleleje med en løbebane (14, 15) til i det mindste en rullelegemerulle (13) omfattende: tilvejebringelse af en på en endeside af løbebanen (14, 15) placeret kant (31) til udledning af aksiale kræfter, som strækker sig bort fra løbebanen (14, 15); og frembringelse af en anløbsflade (32), som vender mod løbebanen (14, 15) til rullelegemeruller på kanten (31), idet krumningen af anløbsfladen (32) fra et startpunkt (33) hen til en ende (34) på anløbsfladen (32) hver især falder strengt monotont, idet startpunktet (33) er placeret mellem en indvendig, til løbebanen tilgrænsende ende (36) på anløbsfladen (32) og en udvendig, fra løbebanen bortvendt ende (34) på anløbsfladen (32), og krumningen på anløbsfladen (32) fra startpunktet (33) til de to ender på anløbsfladen (32) falder strengt monotont, eller idet startpunktet (33) er placeret i den indvendige, til løbebanen tilgrænsende ende (36) på anløbsfladen (32).
