| KBSThe provided super linear bearings comply with the new standards for linear motion bearings. The rated load of this super linear bearing is three times that of the original, and the moving life is 27 times that of conventional linear bearings. Meanwhile,KBSThe automatic adjustment function of the super linear bearing can save you installation time and extend its movement life by reducing the friction between the shaft and the ball. Super linear bearings are designed to meet the needs of all users and can be used in automation equipment, industrial machinery, electrical equipment, measuring instruments, and more.KBSSuper linear bearings can not only reduce your cost losses，It can also improve the performance of your machine. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The uniquely designed ball plate is made of quenched steel, with precise grooves slightly larger than the size of the balls, thereby increasing the contact area between the balls and the ball plate. And the axis of this design method Capable of carrying a rated load three times that of conventional linear bearings. Automatic adjustment The ball plate is convex, so a pivot point can be provided in the center, which can automatically adjust the bearing by 0.5 °. The automatic adjustment capability of bearings eliminates all mechanical inaccuracies caused by inaccuracies The possibility of edge pressure caused by processing, installation failure, or axis offset. Longer operating lifespan KBSThe rated load of the super linear bearing is three times that of the original, and the operating life is 27 times that of the conventional linear bearing. Smooth and silent movement Due to the unique design of the retainer and outer sleeve, the movement of the super linear bearing is very smooth. The retainer and outer sleeve are made of engineering polymer, which is lightweight and has low friction And the wear resistance is small. Therefore, it ensures the smooth movement of the super linear bearing. Gap and adjustment The ball plate of the super linear bearing is designed for use in the outer sleeve. This allows the gap between the ball and the shaft to be adjusted by using a clearance adjustment bearing housing, thereby adapting it to the optimal stress Using the environment. interchangeability The design of super linear bearings can be completely interchangeable with conventional linear bearings. 
The automatic adjustment function can compensate for inaccurate machining of the base point, so it can save you installation time and also reduce your costs. Higher rated load and longer moving life Compared to conventional linear bearings of the same size, super linear bearings provide higher rated load and longer operating life. Reduce material costs Super linear bearings have a higher rated load, allowing for the use of smaller components and reducing material costs. energy saving The design of super linear bearings is lightweight, low inertia, and has low friction. So the moving parts can operate at higher speeds with lower driving power.
Basic rated dynamic load（c）And the lifespan of mobility The operating life of super linear bearings is mainly determined by the quality of the shaft. The basic rated dynamic load is 90% reliable achieved by the super linear bearing after running for 50 kilometers under normal conditions The maximum load that can be continuously applied to a super linear bearing under sexual conditions. The nominal operating life of a super linear bearing can be calculated using the following equation.
In fact, other factors can also affect the operating life of bearings, as shown below:
Based on the above equation, when the stroke and frequency are constant, the operating life of the bearing can be calculated using the following equation:
Calculation Example The maximum load applied and operating life are the most important factors in selecting the appropriate size of super linear bearings. The following are some calculation examples for calculating the expected operating life, which you can choose based on A super linear bearing of appropriate size. ——Working conditions—— ·Applied load: 250N (P) ·Journey: 0.250 meters (Ls) ·Milestones per minute: 60 (Nr) ·Shaft hardness: HRC 60 (hr=1.0) ·Operating speed:
Calculation of expected lifespan: Assuming the basic rated dynamic load has a base life of 50 kilometers and all other factors are 1.0, choose the size of the super linear bearing that you can expect to have a lifespan of. For example, in the above work order Under the itemLMES20UUThe calculation can be carried out as follows:
Choose an appropriate super linear bearing Assuming our designed lifespan is 15000 hours:
Housing The application of super linear bearings requires the use of bearing housings, and the tolerance of the inner diameter of the bearing housing will affect the life of the bearings and the accuracy of the application. Please refer to Tables 9 and 10.
axle Due toKBSThe ball bearings in super linear bearings operate directly on the surface of the shaft as rolling elements, so the hardness, surface processing, and tolerance of the shaft will significantly affect the super linear bearings The mobility performance. The shaft must meet the following conditions: 1) Hardness The hardness must beHRC 58to64. The hardness of the shaft is lower thanHRC 58It will lead to a decrease in mobility lifespan and allowable load. 2) Surface processing To ensure smooth operation, surface processing must be1.6SOr better. 3) Tolerance The recommended correct tolerances for the shaft diameter are shown in Tables 9 and 10. coordinate The recommended assembly between the super linear bearing and the shaft is shown in Tables 9 and 10. Please note that when the tolerance of the inner diameter of the bearing box isH7At that time, both ends of the metric type jacket tube were tightly fitted. |
