Ibicuruzwa

Ibyuma by'umupira birebire (Deep Groove Ball Bearings) ni byo bikunze gukoreshwa mu buryo butandukanye. Ibyuma by'umupira birebire birimo: ibyuma byigenga bifite impeta z'inyuma zikomeye, impeta z'imbere n'ibice by'umupira n'ibisenge.
Zirakora cyane kandi zikomeye, ziboneka mu bunini butandukanye n'amahitamo atandukanye harimo n'udupfundikizo, ingabo n'ahantu hihariye ho gukoreshwa mu buryo bwihuse. Ubwoko bw'ingenzi ni:

Ifunguye - Ifite icyuma gifunga cyangwa inkinzo, ikwiriye gukoreshwa aho amavuta ahora anyuramo, nko: amasanduku y'imodoka.
Udukingirizo tw'icyuma (ZZ cyangwa 2Z) - Udukingirizo dufite udukingirizo tw'icyuma kandi twasizwe amavuta.
Ibyuma bya Rubber Seal (2RS,) - Ibyuma bifite ibyuma bya rubber contact seal bitanga ibyuma byiza ariko byongera uburyaryate bityo ntibikwiriye gukoreshwa mu muvuduko mwinshi, birimo amavuta
Bikoreshwa cyane mu nganda z'ubuhinzi, ibikoresho byo mu busitani, inganda n'ibindi.

6201-1/2" 2Z ni umupira wihariye wa santimetero 1/2, uboneka mu buryo bwinshi.
Ibyuma bya 6201-ZZ-1/2 bifite ingabo ebyiri z'icyuma imwe kuri buri ruhande, zisize amavuta.

Zifite ubwivumbure buke kandi zinogeye urusaku ruto n'ingufu nke, ibyo bigatuma umuvuduko mwinshi uzenguruka. Zifata imizigo ya radial na axial mu byerekezo byombi, zoroshye kuyishyiraho, kandi zikenera gusanwa guke ugereranyije n'izindi verebu.
