Product review (4 stars): High quality Bosch roller/axle replacements work in 4 of the 8 spots on the upper dish rack for my older model Bosch
These roller sets are a high quality product, and come in Bosch labeled packaging.  The design of the axle components (darker grey in the picture), is slightly different than the original design of the axle components on my Bosch upper rack (I have an older Bosch model).  There are several spots where the axle/wheel assemblies can go on the rack.  The wheels fit in all 8 locations of my upper rack, however the newer axle designs fit only 4 of the 8 locations, so I continue to use the original axles in those 4 remaining locations (but with the new wheels).  If you need new axles in addition to the wheels, I advise carefully comparing the pictured axles to your design to check for potential compatibility.
