(1) Burðarálag:
① Ball bearings should be preferred for small or medium loads (because the main components of ball bearings are in point contact)
② Rúllulegurætti að nota fyrir stærri álag (sem þolir stærri álag og höggálag og hefur litla aflögun eftir hleðslu)
(2) Veldu legugerð í samræmi við stefnu álagsins
①Only bear axial load: choose angular contact bearing (one-way thrust ball bearing)
② Only bear radial load: choose single row radial ball bearings (deep groove ball bearings) or tapered roller bearings
③ Bear radial and axial alternating loads: choose tapered roller bearings, angular contact bearings, deep groove ball bearings
(3) Ásfesting rúllulegra (innri hringfestingaraðferð) Einn endi innri hrings legunnar er venjulega staðsettur við öxl eða ermi
①The shaft is fixed with a retaining ring: mainly used for occasions with low speed and small axial load
②The shaft end face retaining ring is fixed: it can be used for high speed, large axial load, and is only suitable for the shaft end
③Fixed by round nut and brake washer: mainly used in occasions with high rotational speed and large axial load
④Fixing the bushing and the round nut structure: it is used to fasten the self-aligning bearing with little axial force and rotation speed on the long shaft.
