2 RADIAL BEARINGS 9x17x4mm TEMPERED STEEL MAXX MODEL (MR689)

Deep groove ball bearings reduce rotational friction and support radial loads. Ideal for precision work with close tolerances suitable for model building and applications.
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls and use balls to maintain separation between the bearing washers. Made of heat treated chromed steel.
