ISO/TC 4/SC 5 - Needle, cylindrical and spherical roller bearings

This document specifies the boundary dimensions for radial needle roller and cage assemblies. In addition, this document gives the tolerances for the cage width and method of functional gauging of bore diameter of needle roller complement. Informative values for the tolerances of shaft raceway, housing raceway and raceway widths are given in Annex A. Functional gauging of radial needle roller and cage assembly is given in Annex B.

This document specifies nominal boundary dimensions, geometrical product specifications (GPS) and tolerance values for finished steel cylindrical rollers for rolling bearings. The maximum roller diameter is 40 mm. Annexes A and B give the sorting principles for roller diameter and roller length tolerances and gauges, respectively.

This document specifies the boundary dimensions and tolerances for thrust needle roller and cage assemblies. Furthermore, it recommends dimensions and tolerances for thrust washers, i.e. raceway members, which can be used either as shaft or housing washers. Annex A gives general characteristics for application of thrust needle roller and cage assemblies and thrust washers. Gauging method for thrust needle roller and cage assemblies and thrust washers is given in Annex B.

This document specifies bearing and subunit boundary dimensions for complete single-row and double-row tapered roller bearings. It also specifies the flange dimensions of flanged outer rings for a selection of these bearings. A series designation for each bearing is also specified.

This document specifies dimensional and geometrical characteristics, nominal boundary dimensions and tolerance values for finished steel needle rollers used as rolling elements.

This document specifies dimensional characteristics, nominal boundary dimensions and tolerance values for needle roller bearing track rollers, yoke and stud types.

ISO 12297-2:2018 specifies dimensional and geometrical characteristics, nominal boundary dimensions and tolerance values for finished silicon nitride cylindrical rollers for rolling bearings. Annexes A and B give the sorting principles for roller diameter and roller length tolerances and gauges, respectively. Annex C gives examples of imperfection types and methods of inspection.

ISO 1206:2018 specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings. ISO 1206:2018 specifies dimensional and geometrical characteristics, and limit deviations from nominal sizes. These specifications apply to complete needle roller bearings and to bearings without inner ring. Recommended values for the tolerances for shaft raceways for needle roller bearings without inner ring are given in Annex A.

ISO 3245:2015 specifies the boundary dimensions and preferred dimensions to be used for drawn cup needle roller bearings without inner ring as well as the minimum chamfer dimension limits. Also specified are the closed end thickness dimensions for bearings with one closed end. In addition, dimensional tolerances for the needle roller complement bore diameter and tolerances for the drawn cup width are specified. Informative values for the tolerances for shaft raceway and housing bore are given in Annex A.

ISO 10317:2008 establishes a system for the designation of metric size tapered roller bearings produced in accordance with ISO 355. The system covers designations for single-row bearings, double-row bearings, and bearings with flanged outer rings. ISO 10317:2008 also establishes designations for separate inner subunits (inner ring, tapered rollers and cage) and outer rings of such bearings. ISO 10317:2008 does not apply to bearings or inner subunits or outer rings which in any respect deviate from ISO 355.

ISO 246:2007 specifies the width, the maximum outside diameter, the bore and the bore minimum chamfer of separate thrust collars for cylindrical roller bearings in diameter series 0, 2, 3, and 4 as specified in ISO 15. Dimensions for overall width and other geometrical features are not specified as they are dependent on the internal design of the bearings.

ISO 12043:2007 specifies the minimum chamfer dimensions for loose rib and non-rib sides of single-row cylindrical roller bearings of diameter series 0, 2, 3, and 4 (except dimension series 24) as specified in ISO 15. Indication is given for those minimum chamfer dimensions that are identical to those in ISO 15.

ISO 3030:2011 specifies the boundary dimensions for radial needle roller and cage assemblies. In addition, it gives the tolerances for the cage width and method of functional gauging of smallest single bore diameter of needle roller complement.

ISO 3245:2007 specifies the boundary dimensions and preferred dimensions to be used for drawn cup needle roller bearings without inner ring as well as the minimum chamfer dimension limits. Also specified are the closed end thickness dimensions for bearings with closed end drawn cups. In addition, dimensional tolerances and methods for checking the needle roller complement bore diameter are specified.

ISO 7063:2003 specifies the boundary dimensions and the tolerances of needle roller bearing track rollers, yoke and stud types.

Specifies a general plan for boundary dimensions and preferred dimensions to be used. For closed end drawn cups dimensions of the end are specified. In addition it gives tolerances and a method for checking of the needle roller complement bore diameter.

Specifies the boundary dimensions for needle roller and cage radial assemblies and gives preferred dimensions to be used. In addition, it gives the tolerances for the width of cages.
