說明:
1.表中所列基本額定載荷、極限轉(zhuǎn)速和重量,僅供選擇參考用。
2.軸承的外圓為圓柱面時(shí),在現(xiàn)軸承型號(hào)后綴加X,例如:NATR5X或NATR5PPX。
3.油潤(rùn)滑時(shí),極限轉(zhuǎn)速為表列數(shù)值增加30%,帶密封的情況除外。
Note:
1.These load, speed and mass is reference of choice only.
2.For cylindrical outer race, add the suffix "X", e.g. NATR5X or NATR5PPX.
3.With an effective oil supply, the limiting speed can be increased by about 30%, except for sealed
roller followers.
