说明:
1、
表中所列基本额定载荷、极限转速和重量,仅供选择参考用。
2、
轴承外圆为圆柱面时,在现轴承型号后缀后X,例如:NUTR15X。
3、 油润滑时,极限转速为表列数值增加30%。
1. These load, speed and mass is reference of choice only.
2. For cylindrical outer race, add the suffix "X", e.g.
NUTR15X.
3. With an effective oil supply, the limiting speed can be increased
by about 30%.
