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 the bearing
No.,the maximum allowable working themperrature is 120? in continuous
working and 180? in short working.
3.With grease lubrication, 60% of these limiting speed will apply.
