ISO ISO/TC 4 Rolling bearings
· Standardization of all types and all sizes of bearing elements based on the principle of rolling motion, includingication and standardization of spherical plain bearings, i.e. plain bearings with spherical contact surface. ISO/TC 4/SC 4
ISO 281:2007 specifies methods of calculating the basic dynamic load rating of rolling bearings within the size ranges shown irdance with good manufacturing practice and basically of conventional design as regards the shape of rolling contact surfaces.
Single bearings and matched bearing pairs arranged in tandem Normal Check availability of C2, C3, C4, C5, reduced ranges of stValues are valid for unmounted bearings under zero measuring load. Matched bearing pairs arranged back to back or face to face
ISO 492:2014 specifies dimensional and geometrical characteristics, limit deviations from nominal values, and tolerance valuesace (except chamfers) of radial rolling bearings. The nominal boundary dimensions are defined in ISO 15, ISO 355 and ISO 8443.

ISO Bearings is the sole importer of ISO branded bearings and power transmission products. The brand was introduced to South Africa in 2007 after the company identified a demand in the market for top quality, affordable products.
The committee responsible for this document is ISO/TC 4, Rolling bearings, Subcommittee SC 4, Tolerances, tolerance definitioncluding GPS). This fifth edition cancels and replaces the fourth edition ( ISO 492:2002 ), which has been technically revised.
Tolerance classes and the corresponding values for certain tolerance characteristics are specified in ISO 492 (for radial bearthese standards were aligned with general ISO GPS (Geometrical Product Specification) standards such as ISO 1101 and ISO 5459.
ISO 15312:2018 defines the thermal speed rating for oil bath lubricated rolling bearings and defines calculation principles fo applies to rolling bearings of the given series and sizes of standard design or of a design that, from a frictional point
