Angular Contact Bearings

Anyone have any experiences using these types of bearings?

If you were to use them, would you use them as either a front or rear bearing?

Problem might be the retainer. With a metal retainer, they will not hold up to our high RPM's. It would take a different retainer either phenolic or TH9 plastic.

Angular contact work great, but you need to use them as a set. You also need to be able to set the thrust preload between the two bearings. THere are some pylon race motors out that use them, but the front bearing is shimmed for the correct prelad and then secured to the case witha special nut assembly. THere is 0 axial play. When set up properly, they are vibration free and good for 100k rpm+. I think that Jin Allen's photo folder has an example of this set up as well. But they are not a simnple swap in replacement.
