From the picture provided, it looks as if there's nothing to space the bearings out from the two side plates. If this is true, a thin spacer the size of the inner race between each bearing and the side plates would stop the entire bearing from contacting the sides and binding. This worked very well for my team's carriage assembly, which uses a very similar slide.
