Bearings are an integral part of most mechanisms, machines and devices in which there are parts rotating around their axis. They can be found in aviation, automotive and even household appliances. Designed to reduce the friction force, they themselves experience fairly strong loads and their planned replacement, in most cases, is carried out in the format of average routine maintenance. Today you can buy bearings using numerous online catalogs, but the selection procedure is complicated by several factors at once:
- The introduction of new types of composite materials makes it possible to manufacture bearings with higher quality indicators, they can be installed (subject to interchangeability) instead of failed classic analogs.
- Inconsistency in the classification of similar (one-dimensional) bearings of imported and Russian production. In most cases, foreign-made equipment can be routinely replaced with more affordable domestic components.
It is guaranteed to understand all the intricacies of bearing selection, for example, equipment for which there is no manufacturer's technical documentation is difficult even for a qualified technologist.
Select by size
Modern software allows you to select the required bearing, if there is no classification number for its dimensional parameters. For this, a specialist will need a caliper-compass with which it will be necessary to remove the following dimensions from the existing sample:
- Inside diameter - means the diameter of the inner ring or shaft on which the bearing is installed.
- Outside diameter - the size of the outer ring or seat is measured.
- Product width - means longitudinal section.
The obtained measurements (in millimeters) are entered into the corresponding parameters of the online catalog, after which the search is activated. The program will display all currently existing types of bearings with similar dimensions (including new designs and imported models). You can decide on the required type using the resource option “feedback from a technical consultant”, who will tell you which bearing is suitable for installation instead of a failed product.
