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 ,150 in temporary working and 180 in short working.
3.With grease lubrication, 60% of these limiting speed will apply.
