China 30202 li-roller bearings, baetsi ba mela e le 'ngoe le barekisi

30202 li-rolara tse tapered, mola o le mong

Tlhaloso e Khutšoanyane:

Li-roller bearings tse nang le mela e le 'ngoe li etselitsoe ho amohela meroalo e kopaneng, ka nako e ts'oanang e sebetsa ka meroalo ea radial le axial. Mehala ea mabelo a mabelo a kopana sebakeng se le seng holim'a axis ho fana ka ts'ebetso ea 'nete ea ho thetheha le linako tse fokolang tsa khohlano nakong ea ts'ebetso. Bokhoni ba ho jara mojaro oa axial oa li-roller tse tapered bo eketseha ka sekhahla sa ho ikopanya α. Boholo ba angle ea ho kopana, eo hangata e leng pakeng tsa 10 ° le 30 °.
