This single row cylindrical roller bearing separates the inner and outer rings into a non-locating configuration, with the outer ring having no ribs and the inner ring carrying two ribs, type N3. Bore diameter is 20.0 mm, outside diameter 52.0 mm, width 15.0 mm, and net mass 175.0 g. The roller set is guided by a solid brass cage, designation M1. The absence of ribs on the outer ring allows axial displacement between inner and outer rings, making this bearing suitable as a non-locating position where axial compensation is required. Radial internal clearance corresponds to CN (Group N), the standard clearance range, providing predictable running behavior under radial load without preload. The solid cage design supports stable roller guidance at higher rotational speeds compared to stamped cage variants.
