myonic RA (standard) and RKA (flanged) series are dismountable angular contact bearings. They must be operated under axial preload and are typically installed in pairs (DB, DF, DT configurations). This design allows for larger ball diameters, providing higher stiffness and load capacity than radial deep groove ball bearings of the same size.
