Precautions for bearing use

compared with general mechanical parts, rolling bearings have higher accuracy, so they should be used with caution accordingly

1) keep the bearing and its surroundings clean

2) be careful when using

if the bearing is carelessly impacted, there will be scars, indentation, fracture and other injuries on the bearing

3) use appropriate tools

4) pay attention to the rust prevention of bearings

avoid using in wet places, and wear gloves to prevent sweat

5) users should be familiar with bearings

6) formulate operation specifications for bearing use

a, storage of bearings

although there are other factors besides the above points

b, cleaning of bearings and their surroundings

c, inspection of size and processing quality of installation parts

d, installation operation

e, inspection after installation

f, disassembly operation

g.maintenance (regular inspection)

h Supplement of lubricant

advantages and disadvantages of bearings in this section, how to distinguish the quality of bearings

distinguish the quality of equipment bearings, we usually proceed from the following aspects:

whether the outer packaging is clear:

generally, the brands produced by regular manufacturers have their own special designers to design the outer packaging, and arrange factories with qualified production conditions for production, so, The packaging of products should be very clear and unambiguous from lines to color patches

whether the steel seal words are clear:

and some conductive materials are transparent. Every bearing product will be printed with its brand words, labels, etc. on the bearing product body. Although the font is very small, the products produced by regular manufacturers use steel printing technology to print, and they are pressed before overheating treatment. Therefore, although the font is small, it is deeply concave and very clear. In general, the font of counterfeit products is not only vague, but also floating on the surface due to the rough printing technology. Some of them can even be easily erased by hand or the manual marks are serious

whether there is any noise:

hold the inner sleeve of the bearing with your left hand, pull the sleeve with your right hand to rotate it, and listen to whether there is any noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products and the complete manual workshop operation, impurities such as dust and sand will inevitably be mixed into the bearing body during the production process, so there will be noise or unsmooth operation when the bearing rotates. This is the key to judge whether the products come from the brand products of regular manufacturers with strict production standards and machine operation

whether there is muddy oil on the surface:

whether there is muddy oil on the surface requires special attention when purchasing imported bearings. As there is still a certain gap between the current domestic rust prevention technology and foreign advanced manufacturing countries, it is easy to leave thick traces of oil when carrying out rust prevention treatment on the bearing body, which feels sticky and thick when touching with hands, while almost no traces of rust prevention oil can be seen on the bearings originally imported from abroad. According to insiders, people who are particularly careful can smell a special smell on imported bearings, which is the smell of antirust oil

whether the chamfer is uniform:

the so-called chamfer of bearings, that is, the junction of horizontal and vertical surfaces. What's the matter with counterfeit bearing products that can't be loaded due to the torsion testing machine of production technology? We can easily distinguish that the treatment of these corners is not satisfactory
