Bearings are responsible for the free, unhindered rotation of parts of the mechanism or machine and are rings with reduced friction among themselves. Low-quality products can lead to damage to mechanisms. Therefore, it is so important to choose quality bearings.
Instructions
Step 1
When choosing bearings, focus on a thorough visual inspection. If there is packaging, consider it. Curved font in the inscriptions and floated colors are unacceptable. Hand-staining packaging paint is a bad indicator.
Step 2
Before buying bearings, see if the package contains the name of the specimen, the country of manufacture, the manufacturer, and the date of issue. This is true if there is no attached passport. The packaging must be free from any fall marks.
Step 3
Make sure that there is no corrosion or traces of corrosion on the products themselves. High-quality bearings should be free of stains, scoring and other signs of damage, not only in the working area, but also on the rest of the surface.
Step 4
Check if the bearings, except for the smallest ones, have information about their origin. Compliance of Russian bearings with standards must be confirmed by a passport containing information about the manufacturer, product designation in accordance with GOST, date of conservation (packaging), warranty storage periods. These terms can range from six months to a year. After the expiration of the specified period, the products are re-preserved, indicating the date of this procedure in the passport. Imported bearings do not have passports, so their characteristics should be displayed on the packaging.
Step 5
Choose the right place to buy bearings. Do not go to questionable outlets. Decent companies are always responsible for the quality of the product they sell. When choosing bearings, do not hesitate to ask the consultant the questions you are interested in. High-quality service involves the provision of qualified assistance in their selection.
