In addition to the quality of bearings, but also belong to a very precise parts, both high-performance bearings, if in the process of using improper use, not only can not achieve the expected performance effect, but also easy to make the bearing damage, in the lubrication aspects oaf everyone must have paid attention to. In addition to lubrication, bearing in the use of the process, there are those aspects need to pay attention to it?

First, the use of installation should be careful

Do not allow strong stamping, do not allow direct hammering of the bearing, do not allow the transmission of pressure through the rolling body.

Second, the use of appropriate and accurate installation tools

Try to use special tools, strongly avoid the use of cloth and short fibres and such things.

Third, try to keep the bearing and its surrounding environment clean

Even if the naked eye can not see the smile dust into the bearing, it will increase the bearing wear, vibration and noise.

Four, prevent the bearing from rust and corrosion

When picking up the bearings directly by hand, wash away the sweat on your hands sufficiently and apply high quality mineral oil before operation, especially in the rainy season and summer to prevent rust.

Under certain special operating conditions, bearings can achieve a longer life than traditionally calculated, especially under light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the possible surface damage caused by contaminants is limited. In fact, under ideal conditions, so-called permanent bearing life is possible.

When dismantling the bearings for maintenance, the bearings are first cleaned by recording the appearance of the bearings, confirming the amount of lubricant remaining and taking a sample of the lubricant used for inspection. As a cleaning agent, petrol and paraffin are commonly used.

The cleaning of the dismantled bearing, divided into coarse cleaning and fine cleaning, respectively, placed in the container, first put on the metal mesh pad bottom, so that the bearing does not directly contact the container of dirt. Coarse cleaning, if the bearing with dirt rotating, will damage the rolling surface of the bearing, should be noted. In the coarse cleaning oil, use the brush to remove to grease, adhesion, roughly clean, transferred to the fine cleaning.

Fine washing, is the bearing in the cleaning oil while rotating, while carefully cleaning. In addition, the cleaning oil should also be kept clean regularly.

Bearing overhaul and judgement: In order to judge whether the dismantled bearings are ready for use, they should be checked after they have been cleaned. Check the condition of the raceway surface, rolling surface and mating surface, the wear of the cage, the increase of the bearing clearance and the damage of unrelated dimensional accuracy decrease, abnormal. Non-separate small ball bearings, then use a hand to support the inner ring level, rotate the outer ring to confirm whether the smooth, tapered roller bearings and other separate-shaped bearings, can be rolling body, outer ring of the raceway surface were checked.
