Answer
Bangaren da aka riƙe (bangaren da ake riƙe a wurin) galibi yana da chamfer ko radius a gefensa don sauƙin masana'anta. Koyaya, wannan chamfer yana haifar da 'ramp' wanda ke aiwatar da sashin radial na ƙarfi $F_r = F_a \tan(θ)$ akan zoben riƙewa, inda $F_a$ shine ƙarfin axial kuma $ heta$ shine kusurwar chamfer. Wannan ƙarfin radial yana ƙoƙarin tura zobe daga cikin tsagi. Idan chamfer ya yi girma sosai, zai iya sa zoben ya 'tasa' kuma ya gaza da wuri. The maximum allowable chamfer or radius on the retained part is typically specified in the ring's technical data sheet (e.g., $r_{max} < 0.5 \cdot d$, where $d$ is the groove depth). Idan babban chamfer ba zai yuwu ba, dole ne a yi amfani da injin wanki mai kaifi-square don tabbatar da cewa an yi amfani da lodin axially a fuskar zobe.
