Linear rolling bearing，Such as linear bearing、Ball linear bearings and roller linear bearings, etc，With its unique performance characteristics, it has been widely used in many industrial fields。The following are the main performance characteristics of linear rolling bearings：

1. Strong carrying capacity

• The bearing capacity of linear rolling bearings is that of plain bearings3More than，ball-bearing10More than。This allows them to withstand large axial and radial loads，It also has good torque transmission ability。

2. High precision

• The sliding surface of linear rolling bearings is usually flat or curved，Its high precision requirements can be achieved through high precision manufacturing and assembly。Curved linear bearings can even change the accuracy of bearings by adjusting the position of bearing support points，Meet high precision requirements。

3. Run smoothly

• The running of linear rolling bearings is very smooth，Low friction coefficient，Low motion resistance。This allows them to maintain stable performance at both high and low speeds，It also reduces noise and vibration。

4. Long life

• The life of linear rolling bearings is much longer than plain bearings and ball bearings，Generally attainable5Over 10,000 kilometers。Even at high speed and under harsh conditions，Its lifespan is also guaranteed。

5. Low friction factor

• The friction factor of linear rolling bearings is usually very low，Such as the friction factor of ball linear bearings in general0.0010.004among，For sliding guide pairs only5%2%。This greatly reduces energy consumption，Improved efficiency。

6. Flexible movement、shockless

• The speed of motion allowed by linear rolling bearings is much higher than that of sliding guides，More than ten times the size of the sliding rail。meanwhile，At low speed microfeed，Good control of position dimensions，No idling skid will occur，And it can achieve ultra-micro meter precision feed。

7. Easy maintenance and lubrication

• The structure of linear rolling bearings is relatively simple，Easy to disassemble and repair。meanwhile，Its lubrication system is simple，Generally, grease can be injected regularly on the moving surface，Reduced maintenance costs。

8. Wide range of application

• Linear rolling bearings can be used in CNC machine tools、Mechanical arm、Rail vehicle、Electronic equipment、Air conditioning equipment、Packaging machinery、Medical equipment and other fields。They play a key role in these areas，Improve the overall performance and efficiency of the equipment。

9. Self-adjusting ability

• Certain linear rolling bearings（Such as some ball linear bearings）Has the ability to self-adjust，Can reduce the processing accuracy requirements of phase accessories，Make installation and adjustment more convenient。

10. Flexibility and variety

• There are various types of linear rolling bearings，Like standard type、Gap type and open mouth type，To meet the requirements of different application scenarios。meanwhile，Its compact structure，It is conducive to the miniaturization of machinery。

To sum up，Linear rolling bearing with its strong bearing capacity、High precision、Run smoothly、Long life、Low friction factor、Flexible movement、Easy maintenance and lubrication and a wide range of applications，It plays an important role in industrial production。
