This part of ISO 5753 specifies values of radial internal clearance for the following types of radial rolling bearings: — radial contact groove ball bearings, except those for insًert bearings, — double-row self-aligning ball bearings, — cylindrical roller bearings, — needle roller bearings, except drawn cup needle roller bearings, — toroidal roller bearings, — double-row self-aligning roller bearings. It gives radial internal clearance values for all six types of bearing with cylindrical bore and also for double-row self-aligning ball bearings, cylindrical roller bearings, toroidal roller bearings and double-row self-aligning roller bearings with tapered bore. Values of radial internal clearance for insert bearings are specified in ISO 9628.
