ISO 3584 is an International Standard on plain bearings. ISO 3548-2 is the second part in the multi-series of documents that is applicable to the plain bearings on thin-walled half bearings with or without flanges. Conformity to ISO 3548-2 helps maintain geometrical precision and accuracy in the manufacture of bearings for various applications.
ISO 3548‑2 specifies, in accordance with ISO 12301, the checking of the wall-thickness of thin-walled half bearings with or without flange and describes the necessary checking methods and measuring equipment.
ISO 3548‑2 applies to a maximum bearing diameter of 150 mm. It can be applied to a bigger diameter, provided that there is an agreement between the supplier and the user.
ISO 3548‑2 on thin-walled half bearings with or without flange is relevant to:
Plain bearings are widely used across industries where sliding, rotating, oscillating or reciprocating motion are present. They are mainly used in applications where precision and geometrical accuracy is a critical feature for performance.
To ensure the required bearing clearance, and consequently, the operational efficiency of the plain bearing unit, ISO 3548‑2 recommends the wall thickness tolerances specified in ISO 3548‑1.
ISO 3548-2 can also help identify the presence of grease, dirt, burrs, and other similar components, as well as damage or deformation on the outside surface that may impair the measurement. As a result, this will help you in avoiding inaccuracy in measurements.
As a manufacturer, inspecting the wall thickness of thin-walled bushes in accordance with ISO 3548-2 can help you establish conformity with international standards, thus fostering confidence and reliability for your products.
