What is ISO 11687-2 about?

ISO 11687-2 is the second part of the multi-series of International Standard on plain bearings.

ISO 11687-2 is applicable to the plain bearings on pedestal plain bearings.

ISO 11687-2 specifies design characteristics for side flange bearings for the size range 9 to 28, as well as design characteristics for shafts.

Note: ISO 11687-2 is applicable to side flange bearings used mainly in electrical and turbo engineering industries.

Who is ISO 11687-2 for?

ISO 11687-2 on design characteristics of side flange bearings is relevant to:

Manufacturers and suppliers of side flange bearings
Electrical and turbo engineering industries
Electrical engineers
Civil engineers
Fabricators

Why should you use ISO 11687-2?

Plain bearings are used for sliding, rotating, oscillating or reciprocating motion that support and guide moving components inside the engine. In this regard, side flange bearings are usually applied in horizontal electrical machines such as generators and motors where they are mounted directly to the outside of the machine.

ISO 11687-2 provides you with the classification of side flange bearings according to their design that corresponds to various characteristics such as housing, heat-dissipation, shape of bore for journal bearing and type of lubrication and thrust bearing. Moreover, these characteristics are denoted with symbols, for consistency and clarity amongst users.

Indications on the appropriate dimensions, materials and tolerances are also provided under ISO 11687-2.

Adopting design characteristics with the ISO 11687-2-compliant guidance, will help you ensure of highly efficient and wear-free rotation of these components. Its ability to withstand axial loads or axial thrusts will ultimately prevent corrosion and ensure durable performance of end-products.

What’s changed since the last update?
