Open type linear bearings reasons of quality and external conditions during use due to its carrying capacity, rotational accuracy and wear resistance will change. Open type linear bearing performance is lower than the requirements wa s not working properly, open type linear bearings fault or failure, open type linear bearings h in the event of failure and other unforeseen circumstances, the machine, the machine will stall, loss of function and other anomalies, so find out the cause, and take appropriate measures in the short term.bearing suppliers
First, in the aspect of the installation to be noted that the steps and methods of installation when the installation is correct. Such as cleaning the open type linear bearings and open type linear bearings associated components,
Check the size of the associated components and finishing, install a good open type linear bearings after the necessary checks. These steps should be carried out carefully checked in order to ensure that the open type linear bearing life.
Secondly, the open-type linear bearing running the basic external conditions, for example, monitoring the temperature o f vibration and noise measurement. The detection allows potential problem prevention, open type linear bearing is well protected.
Again, the open type linear bearings at work to correct lubrication, open type linear bearing lubrication divided into grease and oil lubrication. To open type linear bearing function well, to select suitable conditions, the purpose of lubrication. If only consider lubrication, oil lubrication dominant. Grease lubrication can simplify the structure of expertise around the open type linear bearings.
Finally, when open type linear bearing reaches its end-use period should replace it with a new open type linear bearings.thin section ball bearing
 Lubrication of rolling open type linear bearing fatigue life and friction, wear, temperature, vibration have a major impact, there is no normal lubrication, open type linear bearing does not work, the analysis of open ty pe linear bearings causes of damage that about 40% of the open type linear bearing damage and poor lubrication. Open type linear bearing good lubrication is an effective measure to reduce friction and wear of the open type linear bearings. In addition, the open type linear bearing lubrication heat, rust, sealing, impact and effect. To ensure that the lubricant can not be expired, the selection should be correct, harvester open type linear bearing lubrication of oil and grease lubrication two. The large models gearbox oil lubrication select gear oil GL-580W90; greased general lithium grease with molybdenum disulfide grease by twisting CVT lower part of the device must be Mobil XHP222 or better grease.

Installed double row deep groove ball bearings have specific requirements of the site, the site must be kept clean and dry to prevent iron, sand, dust, moisture from entering the bearing.
Bearing common installation tool hand hammer, rod, sleeve, s pecial plate, Lo mosquito fixture, press, the amount of a vernier caliper, micrometer, dial indicator, etc., but according to different bearing model selection tool.
Choose to use the right tools, you can bearings installed, the installation should pay attention not bruised, the corrosion layer, debris, sand, dust, and earth exist, if any, will result in the installation difficulties, it is necessary to maintain double row deep groove ball bearing assembly surface and associated with the parts of the surface clean.ball roller bearing
In addition to the double row deep groove ball bearing assembly surface and associated with the parts of the surface cleaning, but also pay attention to the journal surface of the housing bore of the bearing housing, the end face of the shoulder, and connecting parts such as bushings, washers, cover There is no corrosion layer? If any, with a fine file out fine emery cloth lighting, and then install it.
Rolling bearings are precision components, its use should also be carefully carried out. No matter how high-performance bearings, if used improperly, you will not get the expected performance. Note the use of double row deep groove ball bearings are as follows:
Bearing in use to give a strong impact, will have a scar and indentation, the cause of the accident. Severe cases, crack, fracture, it must be noted.
2, to maintain double row deep groove ball bearing and the surrounding clean
Even the eyes can not see dust, will adversely affect the bearings. Therefore, to keep the surrounding clean so that dust will not invade bearings.deep grove ball bearing
3, using the appropriate operational tools
Avoid existing tools instead, you must use the right tools.
4, pay attention to corrosion of bearings
Operating double row deep groove ball bearings , the hands sweat will become rusty. Should pay attention to clean hands operation, it is best to try to wear gloves.
