How to choose bearings

108115All bearings of the same design and size are similar to each other like twins - and it is sometimes difficult to choose a bearing without certain skills and personal experience.

Surprisingly, the main thing in choosing bearings is trust:

1. You yourself must trust the brand - the factory manufacturer of bearings. It is likely that the market of bearings has already formed a definite opinion about the quality of a certain brand of bearings.

2. Or you should trust the seller of bearings, which recommends to buy one or another bearing - because it is very easy to load an inexperienced buyer with numbers and information. For example, specifying the country of the manufacturer from Europe - when, in fact, it was made in Southeast Asia. On the quality of the bearing it says nothing, but is misleading the buyer. Many European bearing factories have their production in Asia.

3. Or if you are advised to buy a certain brand of bearings by your “friend”, then you need to evaluate his competence - his own experience in operating or repairing certain technical mechanisms.

All this needs to be taken into account, because it is impossible to determine for yourself (by turning the bearing in your hands) whether the bearing is of high quality or not. With equal probability, you can buy a good bearing and buy a “left”, counterfeit, counterfeit bearing, made in a non-certified factory.

Of course, it is possible to carry out a bearing-destroying examination - but it is expensive, long and does not solve your urgent technical problems.

So be careful yourself. Twist it in your hands - it calms down 🙂. You will probably feel a slight backlash of the outer and inner rings - this should not be frightened. This backlash is called a gap and is found in many bearing designs - otherwise the bearing in the working heated state will jam.

Take a close look at the bearing itself from TechnoMaster. The surface of the metal should be clean and evenly treated, it should not be chipping, chipping, cracking.

Check the labels on the packaging and on the bearing itself. Inscriptions should be clear - well readable, without spreading letters and numbers. Sometimes on imported bearings on the bearing itself there is a brief marking, and on the package it must be complete - this is normal practice.But the name of the brand of the manufacturer's plant on the bearing and on the packaging must match. Bearing packaging from good manufacturers should be of decent quality with high-quality printing and have clear labels. Industrial bearings, especially from the CIS countries, most often go without packaging - this is also in the order of things.

Sometimes the bearing on Tehnomaster.net is selected based on the cost. But here there are some subtleties. A good bearing has a higher service life. You must evaluate not only the cost of the bearing as a spare part, but also the cost of all expenses in the event of its failure. It's one thing if you change the bearing in your home vacuum cleaner and do it yourself and is a completely different case if you buy a bearing for repairing the gearbox of a truck. Compare not only the savings on the purchase of a cheap “suspicious” bearing, but also the consequences in the event of a car breakdown: transportation to a service station, troubleshooting, removal and disassembly of the mechanism, finding the necessary spare parts, direct repair and installation in place, and lost time nerves.Everything is obvious - you should not save on the quality of bearings. Quality bearings are your peace of mind and safety.
