Note:
1. These load, speed and mass is reference of choice only.
2. If the cages are made of plastics, 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.

4. The inner race will be supplied with single.
