We have a machine that we manufacture which has two bearings. We're in the process of trying to find some new bearings that will have good performance characteristics in cold weather. So I've tried to come up with some way of testing this, as I couldn't find anything off-the-shelf. If you have any suggestions for making this device cheaper / simpler / better then by all means let me know.

I'll be putting the various bearings in the freezer and then testing them at cold temperatures.

The idea is to have a frame element that can be clamped onto the outside of the bearing and an element clamped or expanded into the ID of the bearing. The central part will need to have some weight to it so that it has enough energy to revolve a number of times. The spring is tensioned against a pin on the frame, hits a stop and then is released. A counter on the frame then picks up on a magnet to count the number of revolutions. The thinking behind this type of spring is that it may be able to accelerate the mass and then carry on to another stop so that it doesn't interfere with the pin on the frame at the next revolution. It may be necessary to make the pin on the frame movable to allow for the two different outside diameters of the bearings.
