Hey Henning,

Your idea to replace the needle bearing with a regular bearing is a good one. We are going start shipping Drives like this in the near future.

What we are trying to do now is find a bearing that will work with the existing plastic bearing retainer. If we can't do this we will just redesign the bearing retainer to use a clamp plate and a flanged bearing
