軸承由一個(gè)圓筒形外圈和多列鋼球及保持架組成。軸承可在軸上做往復(fù)直線運(yùn)動(dòng)。鋼球列數(shù)多、摩擦力小,輕便靈活,使用壽命較長(zhǎng),便于維修保養(yǎng)與更換。
This type bearing consists of a sleeved outer ring, multi-row balls and a retainer. It can make linear reciprocating displacement on a matching shaft. The more the ball rowsare, the less the friction force is, so that it becomes flexibility long running life and easy maintenance and replacement.
