Note: |
| 1. These load, speed and mass is reference of choice only. |
| 2. If the cages are made of plastics, suffix "TN" is added to bearing No., the maximum allowable working temperature is 120 C in continuous working and 180 C in short time working. |
| 3. With grease lubrication, 60% of these limiting speed will apply. |
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. 轴承的保持架如由朔料制成,在型号后加TN，允许工作温度: 120 C连续，180 C短期。 |
| 3. 脂润滑时,极限转速为表列数值的60%。 |
