Daily judgment of rolling hardware bearings

It is understood that knowing it can be used, to understand the functionality of hardware tools, in order to use it. Bearings, you can look at its finish (or roughness) first, the quality is good, you don't have to talk about it. Looking further, you can hold the bearing in your hand and turn it hard to see if it rotates very smoothly and naturally, without noise.

    The general 6xXXX series bearings used by nsk are really easy to use, that is, the price is more than double that of domestic ones. But its life is high, compared to most domestic bearings, one can be used for the top two. So the price is still cost-effective.

    There aren't many shops selling professional bearings. You can go to the hardware store to buy them. (There are some places where you can sell auto parts, motorcycle parts, and belts.) You don't have to go to a small shop. Generally, fixed stores with such bearings will make a very eye-catching brand. When you buy, you ask them to invoice, generally do not give fakes.

    I have used Harbin in domestic bearings, and it is more affordable to buy. The quality is also good. But after a long time, the noise is a little loud and needs lubrication, otherwise it should be rusted.

    Singapore's bearings are of quality between nsk and domestic.
